50 Leading Thought Leaders on Crisis Management

Introduction

The leaders who truly distinguish themselves do not simply respond well to crises. They change how their organisations think about crisis long before one arrives. When a product recall lands on a CEO's desk at 11pm, when a data breach notification hits at 3am, when a natural disaster renders an entire operational site unreachable and the media is already calling: the difference between an organisation that emerges stronger and one that fractures permanently is rarely technical. It is almost always human. It is about the quality of the thinking that preceded the moment, the clarity of the communication that follows, and the resilience of the leadership team that carries everyone through.

Crisis management is one of the fastest-evolving disciplines in global leadership, and it is one of the most consequential. Research from Deloitte found that 75 percent of organisations that experienced a major crisis without a pre-existing crisis management plan reported significant long-term damage to their brand and stakeholder relationships. By contrast, organisations with well-rehearsed crisis plans consistently recover faster, retain more stakeholder trust, and often emerge with stronger reputations than before. The difference is not luck. It is preparation, leadership, and the quality of the thinking that underlies both.

Yet the field is poorly understood by most leaders. Many executives conflate crisis management with crisis communication, assuming that a good PR team is sufficient protection. Others focus on operational continuity and miss the psychological and cultural dimensions of crisis leadership entirely. And in a world where the World Economic Forum's Global Risks Report 2026 ranks societal polarisation, misinformation, extreme weather, and state-based armed conflict among the most severe near-term threats facing organisations, treating crisis management as a niche specialty rather than a core leadership competency is no longer defensible.

This list brings together fifty of the most important voices in crisis management globally. Jonno White is a Certified Working Genius Facilitator and bestselling author of Step Up or Step Out, with over 10,000 copies sold globally. He works with leadership teams navigating high-stakes decisions, difficult conversations, and the team dynamics that determine whether an organisation holds together when pressure is at its highest.

Why Crisis Management Matters

The stakes of getting crisis management wrong have never been higher. A study by Oxford Metrica found that companies that mismanaged major crises destroyed an average of 30 percent of their shareholder value over the following twelve months. Companies that handled their crisis well gained, on average, 10 percent above what the market would otherwise have predicted. The financial case for crisis preparedness is as clear as the ethical one.

Beyond the financial argument, the human cost of poorly managed crises is immense. Employees lose trust in leadership, often permanently. Communities affected by corporate or institutional failures carry the consequences for years. And in an era of social media, the window in which a crisis can be contained or escalated is measured in hours, not days. The most consequential crisis management decision most organisations will ever make is the one they made before the crisis arrived: whether to invest seriously in preparedness or to leave it until they needed it.

Following the right voices in this space is not about accumulating theory. It is about understanding the full spectrum of what crisis leadership demands. The thinkers on this list come from corporate communications, academic research, emergency management, military leadership, geopolitical analysis, business continuity, and technology security. Together, they represent the intellectual architecture of how organisations survive, adapt, and sometimes become genuinely stronger in the aftermath of adversity.

Jonno White, bestselling author and host of The Leadership Conversations Podcast with 230 episodes reaching listeners in over 150 countries, works with leadership teams who want to build the cultural foundation that makes crisis management possible. Organisations that are psychologically safe, that have strong team dynamics, and that have practised honest conversations about risk are the ones that hold together when everything else is falling apart.

How This List Was Compiled

The fifty people on this list were selected because they have each made a genuine, specific, and verifiable contribution to how the world thinks about and practises crisis management. The selection process prioritised disciplinary diversity across corporate communications, organisational resilience, academic research, emergency management, military and geopolitical risk, and technology security. Geographic representation spans the United States, United Kingdom, Canada, Australia, the Netherlands, Sweden, Singapore, and more. The aim was to surface voices doing original work in the field, rather than recycling the same names that dominate every other list. Where a well-known voice in adjacent leadership fields appears, it is because their specific work directly addresses how organisations prepare for and respond to crises, not because they are generically influential. Gender balance was a deliberate priority throughout the selection process.

Category One: Corporate Crisis Communication Architects

The first discipline that most leaders encounter in crisis management is crisis communication. How an organisation communicates when everything is going wrong determines not just the outcome of the immediate crisis, but the long-term trajectory of its relationship with every stakeholder it depends on. The people in this category have built careers around the question of what to say, when to say it, and how to say it with credibility under pressure. They represent some of the most practised, most specific, and most battle-tested thinking in the field.

1. Edward Segal

As a Forbes senior contributor who has written over a thousand articles on crisis management and leadership strategy, Edward Segal has become one of the most prolific and accessible voices in the field. His decades of experience as a crisis management consultant, association executive, and media commentator give his writing a specificity that distinguishes it from theory. He brings real cases, real organisations, and actionable frameworks to every analysis he publishes.

His 2025 book The Crisis Casebook: Lessons in Crisis Management from the World's Leading Brands, published by John Murray Business, distils lessons from hundreds of real-world corporate crises into a practical roadmap that leaders can apply before and during their own. Segal's weekly Crisis Management Minute podcast extends his reach to practitioners who prefer audio, and his consistent output means his thinking stays current with the most recent cases and challenges facing organisations in 2026.

2. Melissa Agnes

The founder and CEO of the Crisis Ready Institute, Melissa Agnes has spent over fifteen years helping some of the world's most complex organisations build what she calls invincible brands. She has worked directly with NATO, the Pentagon, world leaders, and Fortune 500 organisations, helping them understand that crisis readiness is not a plan sitting in a drawer but a cultural state that either exists or does not.

Her Crisis Ready methodology is taught at Harvard and universities worldwide. Agnes's 2018 book Crisis Ready: Building an Invincible Brand in an Uncertain World remains one of the most practically oriented frameworks available to practitioners. What makes her perspective distinctive is her insistence that crisis management is fundamentally a leadership development challenge, not a communications challenge, and her coaching work with senior leaders reflects this conviction.

3. Deborah Hileman

President and CEO of the Institute for Crisis Management, a US-based consulting firm founded in 1990, Deborah Hileman brings more than thirty-five years of experience to the most demanding communication challenges organisations face. She holds multiple credentials including Fellow of the Centre for Strategic Communication Excellence, Corporate Crisis Management Certified, and a FEMA-trained NIMS Incident Commander.

In 2025, she was honoured with the IABC Rae Hamlin Award for her advocacy of global communication standards, and she currently serves as vice-chair of the Global Communication Certification Council. Hileman has led high-performing teams through healthcare crises, manufacturing failures, insurance disputes, financial investigations, and higher-education challenges, making her one of the most credentialled and broadly experienced practitioners in the field.

4. Erika James

The Dean of the Wharton School at the University of Pennsylvania, Erika James is also one of the most rigorous academic researchers in crisis leadership. Her 2022 book The Prepared Leader: Emerge from Any Crisis More Resilient Than Before, co-authored with Lynn Perry Wooten, draws on decades of research into how leaders behave under pressure and what distinguishes those who prepare well from those who improvise badly.

James has studied how organisations can use crises as accelerants for transformation, arguing that the most important variable is not the nature of the crisis but the quality of the leadership response. Her research has influenced how organisations design crisis preparedness programmes, and her position at Wharton gives her work direct reach into the next generation of senior executives who will lead organisations through the crises of the coming decade.

5. Lynn Perry Wooten

The President of Simmons University and co-author of The Prepared Leader with Erika James, Lynn Perry Wooten has spent three decades studying the intersection of leadership competencies and crisis response. Her research focuses specifically on the developmental aspects of crisis leadership: how organisations can build, test, and refine their crisis capabilities before they need them.

Wooten's most influential contribution to the field is her work on crisis leadership as a learnable skill set rather than an innate trait, a reframing that has direct implications for how organisations design training, simulation, and succession planning. Her research into how women heads of state led through the first wave of COVID-19, published in Organisational Dynamics in 2022, introduced important comparative data on how leadership style affects crisis outcomes.

6. Paul Argenti

Professor of Corporate Communication at the Tuck School of Business at Dartmouth, Paul Argenti has been teaching and writing about corporate communication and crisis leadership for nearly four decades. His textbook Corporate Communication is one of the most widely assigned in business programmes globally, and his work on reputation management and crisis response has shaped how generations of executives approach stakeholder communication under pressure.

Argenti's research has examined how companies from Johnson and Johnson to more recent corporate cases have navigated product crises, leadership failures, and reputational attacks. He is notable in the field for his emphasis on the relationship between organisational values and crisis communication credibility: leaders who have established clear values before a crisis find those values are an asset during it, while those who have not find them a liability.

7. Ronn Torossian

Founder and CEO of 5WPR, one of the top independent PR firms in the United States, Ronn Torossian has managed some of the most challenging corporate communications crises in the modern media environment. His 2011 book For Immediate Release: Shape Minds, Build Brands, and Deliver Results with Game-Changing Public Relations remains one of the most direct practitioner accounts of what crisis communications actually requires on the ground.

Torossian's perspective is shaped by the reality of 24-hour news cycles and social media amplification, and his writing consistently addresses the speed gap between when crises develop and when most organisations are ready to respond. His LinkedIn commentary on current crisis events gives practitioners real-time analysis of how organisations are performing when they are most under scrutiny.

Category Two: Academic Architects of Crisis Management Theory

Some of the most important advances in how organisations understand and prepare for crises have come not from practitioners but from researchers who have spent careers building conceptual frameworks that give practitioners something rigorous to work from. The people in this category have built the intellectual architecture of the field, from foundational theories of how crises escalate to empirical research on what distinguishes effective crisis leaders from those who make things worse.

8. Tim Coombs

Professor at Texas A&M University and the creator of Situational Crisis Communication Theory, Tim Coombs is arguably the most cited academic researcher in crisis communication. His SCCT framework, which guides organisations in selecting appropriate crisis response strategies based on the type and history of the crisis, is taught in communication programmes worldwide and used by practitioners in every sector.

His book Ongoing Crisis Communication: Planning, Managing, and Responding, now in its fifth edition, is a standard reference text. Coombs' research has addressed how crisis history affects public attribution of responsibility, how social media has changed crisis escalation dynamics, and how organisational culture shapes crisis response. Few researchers have done as much to bring empirical rigour to a field that was long dominated by anecdote and instinct.

9. Arjen Boin

Professor at Leiden University and one of the world's foremost experts on the politics of crisis management, Arjen Boin co-authored the foundational text The Politics of Crisis Management: Public Leadership Under Pressure, together with Paul 't Hart, Eric Stern, and Bengt Sundelius. The book has been translated into multiple languages and remains the definitive academic account of how public-sector organisations navigate crises.

His research addresses the distinctive challenges of government crisis leadership, from the tension between political accountability and operational effectiveness to the role of narrative in shaping public perception of government performance. Boin's work on transboundary crises, where a crisis beginning in one jurisdiction or sector rapidly spreads across borders and systems, is increasingly relevant in a world where cascading crises have become the norm rather than the exception.

10. Paul 't Hart

Professor of Public Administration at the Utrecht School of Governance and co-author with Arjen Boin, Eric Stern, and Bengt Sundelius of The Politics of Crisis Management, Paul 't Hart has been one of the most prolific researchers in crisis leadership for over thirty years. His work spans political crisis management, government accountability, and the psychological dimensions of how leaders make decisions under conditions of extreme uncertainty and time pressure.

His 2019 book Good Governance: The Endless Quest examines how public organisations build and lose the trust that makes effective crisis response possible. 't Hart's comparative research across multiple national case studies, including responses to the pandemic, flooding events, and financial crises, provides practitioners with a genuinely global perspective on what works and what consistently fails.

11. Jeffrey Schlegelmilch

Director of the National Center for Disaster Preparedness at the Columbia Climate School at Columbia University, Jeffrey Schlegelmilch is one of the most credible voices on the intersection of public health, community resilience, and corporate crisis preparedness. His research examines how communities and organisations can build the structural and social capital that makes them more resilient before disasters arrive.

He is the author of Rethinking Readiness: A Brief Guide to Twenty-First-Century Megadisasters, which challenges conventional preparedness models by arguing that the crises most likely to threaten organisations in the coming decade are fundamentally different in scale and character from those that existing frameworks were designed for. His writing for The Hill and frequent media appearances have made him one of the most accessible voices on disaster preparedness in the United States.

12. Lawrence Susskind

The Ford Professor of Urban and Environmental Planning at MIT, Lawrence Susskind is the co-founder of the Program on Negotiation at Harvard Law School and the Consensus Building Institute. His career spans negotiation theory, public dispute resolution, and the management of multi-stakeholder crises where competing interests, incomplete information, and time pressure converge.

His work on cyber negotiation frameworks for critical urban infrastructure, published in partnership with MIT's cybersecurity research programmes, extends classic negotiation theory into one of the most pressing crisis domains of 2026. Susskind's core argument, that the most destructive crises are those where parties cannot find a pathway to agreement under pressure, has implications for every organisation that will face a crisis involving regulators, affected communities, or adversarial counterparts.

13. Chris Clearfield

Co-author of Meltdown: Why Our Systems Fail and What We Can Do About It, published with András Tilcsik, Chris Clearfield brings a systems thinking perspective to crisis management that is distinct from the communications and leadership-focused literature. Meltdown examines why organisations that appear well-run continue to experience catastrophic failures, drawing on research from cognitive psychology, sociology, and systems engineering.

His work is particularly valuable for leaders in high-complexity industries, where the failure modes are often invisible until they are catastrophic. The book's central argument, that tight coupling and organisational complexity create failure conditions that cannot be resolved by better leadership alone, is a necessary corrective to the individual-focused narrative that dominates much crisis management literature.

14. András Tilcsik

Associate Professor at the Rotman School of Management at the University of Toronto and co-author of Meltdown with Chris Clearfield, András Tilcsik holds the Canada Research Chair in Strategy, Organizations, and Society. The United Nations named his course on organisational failure the best course on disaster risk management in a business school, reflecting the direct applicability of his research to real-world crisis preparedness.

His academic research has examined the structural conditions under which errors compound into crises, the role of organisational culture in suppressing early warning signals, and the conditions under which leaders are most likely to miss critical information. Tilcsik's analysis of NASA's decision-making processes and the Deepwater Horizon failure provides particularly clear illustrations of how excellent organisations can still be structurally primed for disaster.

15. Mary Waller

Professor at the Schulich School of Business at York University and the author of Crisis-Ready Teams, published in 2025, Mary Waller has spent her career studying how teams perform under the extreme time pressure and uncertainty that characterise crisis situations. Her research draws on fieldwork in emergency response, healthcare, aviation, and corporate settings.

Crisis-Ready Teams is notable for its data-driven approach: rather than offering principles derived from anecdote, Waller presents specific findings from high-risk team research and translates them into organisational design recommendations. Her work addresses the gap between individual crisis leadership competence and collective crisis team performance, an area that receives far less attention than it deserves.

Category Three: Digital, Cyber, and Information Crisis Experts

The fastest-growing category in crisis management is the intersection of digital threats, social media dynamics, and information integrity. The crises that now move fastest are not operational failures but information events: a viral video, a data breach announcement, a disinformation campaign, or a cyber incident that cascades from a technical problem into a reputational catastrophe within hours. The people in this category are defining how organisations understand and respond to this new crisis landscape.

16. Renee DiResta

A researcher at the Stanford Internet Observatory and one of the world's foremost authorities on how disinformation and coordinated information operations function, Renee DiResta brings a perspective to crisis management that is both technically rigorous and strategically essential. Her research on how false information spreads through digital networks, how state and non-state actors use social media to manufacture crises and amplify real ones, and how platforms govern information during crisis events is directly applicable to any organisation whose reputation can be attacked through online channels.

Her congressional testimony and widely read reports have influenced policy in multiple countries. For crisis managers, DiResta's work is essential reading for understanding what they are actually up against in 2026, when disinformation campaigns and AI-generated content can create crisis conditions faster than any traditional monitoring system can detect them.

17. Martin Gurri

A former analyst with the CIA and author of The Revolt of the Public and the Crisis of Authority in the New Millennium, Martin Gurri has articulated one of the most important frameworks for understanding why institutional crises are more frequent and more severe in the social media era. His central argument is that digital information networks have fundamentally shifted the balance of power between institutions and their publics, making it structurally harder for organisations to maintain credibility and control of narratives during crises.

His work has direct implications for crisis management strategy: organisations that understood Gurri's thesis before COVID-19 were better prepared for the trust collapse that accompanied the pandemic. His consistent LinkedIn commentary on how institutions are navigating current trust crises makes his thinking accessible to practitioners who do not have time to read his full analytical output.

18. Glen Gilmore

A LinkedIn Top Voice and one of the most consistently useful practitioners in digital crisis communications, Glen Gilmore runs the Gilmore Business Network and has been advising organisations on social media crisis management since the platforms emerged as a crisis vector in the early 2010s. His work addresses the speed gap between digital crisis escalation and organisational response.

Gilmore has advised government agencies, global corporations, and nonprofits, and his public commentary on real-time crises gives practitioners a running case study in how organisations are performing at the exact moment crises are unfolding. His focus on how dark social channels amplify early-stage crises before they appear in mainstream media is among the most practically valuable early warning guidance available.

19. Sarah Armstrong-Smith

A leading authority on cyber security and crisis management, Sarah Armstrong-Smith held the role of Chief Security Advisor for Microsoft EMEA from 2020 to 2025, giving her direct insight into how the world's largest technology organisations think about cyber crisis preparedness. She now works as an independent advisor and speaker on the full lifecycle of a cyber crisis.

Armstrong-Smith's perspective on the human dimensions of cyber crisis is distinctive in a field often dominated by purely technical analysis. Her work addresses how non-technical executives can understand what a cyber crisis will actually feel like to lead, which is among the most practically valuable preparation available to senior leadership teams who will face a cyber incident but have no technical background to draw on.

20. Jonathan Kopp

A senior advisor at FGS Global and one of the 2026 Lawdragon 500 Global Leaders in Crisis Management, Jonathan Kopp brings a background that bridges legal, governmental, and strategic communications. He began his career as a Law Clerk to the Counsel to the President in the Clinton White House, before practising at Willkie Farr and eventually moving into strategic communications advisory.

Kopp specialises in situations where legal risk, reputational risk, and political risk converge. His work on how organisations should communicate during cross-jurisdictional investigations, activist pressure campaigns, and media-driven crises is among the most sophisticated available in the field, reflecting his experience with organisations facing simultaneous pressure from multiple directions.

21. Dini von Mueffling

Founder and CEO of Dini von Mueffling Communications, Dini von Mueffling has been inducted into the Platinum PR Hall of Fame and recognised as one of the Top Women in PR by PR News. Her firm's work on crisis communications for high-profile individuals and social impact organisations has produced some of the most awarded communications work of the past decade, including campaigns that won 32 Cannes Lions, 14 Webbys, and an Emmy.

Von Mueffling is particularly well known for her work helping individuals who have become the subject of crisis narratives regain agency over their own stories. Her 2026 appearance as a featured expert at the PRWeek Crisis Communications Conference in Washington DC reflects her standing as one of the most respected practitioners in the field of personal and institutional reputation recovery.

22. Liz Hoffman

A financial journalist and author of Crash Landing: The Inside Story of How the World's Biggest Companies Survived an Economy on the Brink, published in 2023, Liz Hoffman brings investigative reporting skills to crisis management in a way that few practitioners do. Her book examines in granular detail how the CEOs and senior executives of some of the world's largest companies navigated the economic crisis triggered by rising interest rates.

Hoffman's work is valuable precisely because it is not theory: it is reconstructed from interviews with the people who were in the room, giving it a specificity that most crisis management frameworks lack. Her LinkedIn commentary on current corporate crises is among the most rigorously sourced available from a journalist with access to corporate leadership during moments of genuine institutional stress.

Category Four: Emergency Management and Operational Resilience Leaders

Some crises do not begin as communication events. They begin as operational failures: a hurricane, a mass casualty incident, a pandemic, a cyber attack that takes down critical infrastructure. The people in this category have built expertise in the structural and operational dimensions of crisis management, addressing how organisations can design, test, and maintain the systems that allow them to continue functioning when the environment becomes genuinely hostile.

23. Regina Phelps

An internationally recognised thought leader and expert in crisis management, pandemic planning, and exercise design, Regina Phelps has spent decades helping organisations build the muscle memory that transforms crisis plans from documents into practised responses. The founder of EMS Solutions, she is known for her work designing simulation exercises that expose the gaps between how organisations believe they will respond to crises and how they will actually behave.

Her emphasis on exercise design rather than planning reflects one of the field's most important insights: organisations do not need more plans; they need more practice. Her work on the seven leadership skills for crisis management provides one of the most practically structured frameworks available for practitioners who need to translate thought leadership into training programmes.

24. Alissa Dacquisto

Serving as Senior Vice President and Head of Operational Resilience at M&T Bank, Alissa Dacquisto is one of the most experienced practitioners of enterprise resilience in the financial services sector. Her career includes senior resilience leadership roles at both Santander US and Moderna, giving her direct experience designing and operationalising resilience programmes in two of the most crisis-intensive industries of the past decade.

Dacquisto's approach to crisis management integrates risk frameworks, business continuity planning, and leadership development in a way that bridges the gap between strategy documents and actual organisational capability. Her participation as a speaker at the 2026 International Crisis Management Conference reflects her standing as one of the most credible operational voices in the field.

25. Nicole Matejic

The founder of Info Ops HQ and a former Australian Defence Force information operations specialist, Nicole Matejic is one of the most distinctive voices at the intersection of crisis communications and military-grade information operations thinking. Her work translates the rigour and adversarial thinking of defence information operations into frameworks that corporate and government organisations can apply to their own crisis preparedness and response.

Matejic's perspective on how disinformation campaigns and organised information attacks function, and what organisations can do to build resilience against them, is informed by operational experience that very few communications practitioners can claim. Based in Australia, her work addresses crisis management through a lens that is simultaneously local and global, reflecting the reality that information crises do not respect geographic boundaries.

26. Tony Jaques

A Melbourne-based crisis management consultant and author of multiple books on issue and crisis management, Tony Jaques has been one of the most consistent and practitioner-focused voices in the Australasian crisis management community for over two decades. His work on the distinction between issues management and crisis management, which are often conflated but require fundamentally different approaches, is among the most nuanced available.

Jaques has worked with major corporations and government agencies across Australia and the Asia-Pacific region, and his academic contributions to the Journal of Contingencies and Crisis Management have helped build the research base for practitioners in the region. His practical focus on the pre-crisis phase reflects his conviction that most crises are preventable given the right early interventions, and his practical tools for issues escalation monitoring have been widely adopted by organisations throughout Australia.

27. Sattar Bawany

Professor and CEO of the Centre for Executive Education in Singapore, Sattar Bawany published The Making of a CRISIS Leader in 2025, offering what he calls the CRISIS Leadership Model: a framework built around the specific competencies that leaders must develop to navigate the volatile, uncertain, complex, and ambiguous conditions that characterise modern organisational crises.

His work draws on both academic research and his extensive consulting experience with C-suite executives across Asia, the Middle East, and Europe. Bawany's perspective is distinctive for its emphasis on the development of crisis leadership as an intentional and sustained process rather than a reactive response to events, and his work bridges the gap between the Western crisis management canon and the specific cultural and regulatory contexts of Asia-Pacific organisations.

28. Jeffrey Sonnenfeld

The founder of the Chief Executive Leadership Institute at Yale School of Management, Jeffrey Sonnenfeld has spent decades studying how CEOs respond to corporate crises and what distinguishes those who survive and emerge stronger from those who are permanently damaged. His research on CEO crisis response has directly influenced how boards and leadership teams think about executive preparedness, communication strategy, and the relationship between corporate governance and crisis outcome.

Sonnenfeld's high-profile commentary on current corporate crises, which is carried in major media outlets and on LinkedIn, makes his thinking immediately applicable to practitioners navigating real events. His work on why some CEOs accept too much blame and others too little, and the strategic implications of each, is among the most practically useful executive coaching available in crisis management.

Category Five: Geopolitical and Systems-Level Risk Thinkers

The most consequential crises facing organisations in 2026 are not isolated events. They are the products of systems-level disruptions: geopolitical instability, climate events, technological shocks, and the polycrisis reality in which multiple independent crises materialise simultaneously and amplify each other. The people in this category are helping organisations understand and prepare for a class of crisis that sits above the level at which most corporate crisis management frameworks operate.

29. Ian Bremmer

President and founder of Eurasia Group and GZERO Media, Ian Bremmer is the world's leading expert on geopolitical risk and its implications for business and organisational resilience. His annual Top Risks report is one of the most widely read risk documents in the global business community, and his analysis of how geopolitical shifts create operational crises for organisations operating across borders is both rigorous and accessible.

Bremmer's 2022 book The Power of Crisis: How Three Threats and Our Response Will Change the World provides executives with a framework for understanding how global power dynamics translate into specific organisational risks. For any organisation with international operations, supply chains, or regulatory exposure, Bremmer's perspective is essential for understanding the category of crisis that no internal crisis plan can fully anticipate.

30. Michele Wucker

Author of The Gray Rhino: How to Recognise and Act on the Obvious Dangers We Ignore, Michele Wucker coined one of the most useful concepts in modern risk thinking. Where Nassim Taleb gave us the Black Swan, the unforeseeable crisis, Wucker gives us the Gray Rhino: the highly probable, high-impact crisis that organisations can see coming but consistently fail to address.

Her framework is directly applicable to crisis preparedness: most of the crises that destroy organisations are not unforeseeable. They are foreseen, flagged, and then deprioritised for political or financial reasons. Wucker's subsequent research on why organisations fail to act on known risks, and what design interventions can make them more likely to respond to Gray Rhinos before they charge, is among the most practically valuable thinking available to risk managers and crisis planners.

31. Ranjay Gulati

The Paul R. Lawrence Professor of Business Administration at Harvard Business School and the author of Deep Purpose: The Heart and Soul of High-Performance Companies, Ranjay Gulati's research examines how organisations that are anchored in deep purpose navigate disruption, adversity, and crisis more effectively than those whose purpose is shallow or performative.

His work draws on case studies of companies that have been tested by major crises and emerged stronger, demonstrating that the relationship between purpose, culture, and crisis resilience is empirically robust, not merely aspirational. Gulati's 2025 book How to Be Bold: The Surprising Science of Everyday Courage extends this work into the domain of individual leadership courage, the quality most consistently required of crisis leaders.

32. Paul Polman

Former CEO of Unilever and co-author with Andrew Winston of Net Positive: How Courageous Companies Thrive by Giving More Than They Take, Paul Polman represents a distinct stream of crisis management thinking: the argument that the organisations best prepared to navigate existential crises are those that have embedded long-term stakeholder value creation into their operating model rather than treating sustainability as a separate function.

Polman's experience leading Unilever through multiple major crises, including activist investor challenges and supply chain pressures, gives his arguments the credibility of direct operational experience. His work with his Imagine foundation brings this perspective into the governance and leadership development space, where he continues to argue that purpose-driven leadership is the most durable crisis management strategy available.

33. Katharine Hayhoe

Global Chief Scientist at The Nature Conservancy and Paul Whitfield Horn Distinguished Professor at Texas Tech University, Katharine Hayhoe represents an important strand of crisis management thinking that is underrepresented in most corporate frameworks. Her research and communication work focuses on how organisations, communities, and governments can understand and prepare for the escalating physical risks that climate change creates.

Hayhoe's distinctiveness lies in her ability to communicate complex, technically dense risk information in ways that motivate action rather than paralysis, a skill directly applicable to any crisis communicator dealing with difficult and frightening information. Her 2021 book Saving Us: A Climate Scientist's Case for Hope and Healing in a Divided World demonstrated that effective crisis communication about long-term risks requires hope and agency, not just urgency.

34. Fredrik Bynander

Now serving as Deputy Director General at the Government Offices of Sweden and chairman of the board of the Centre of Natural Hazards and Disaster Science, Fredrik Bynander spent many years as director of the Centre for Societal Security at the Swedish Defence University before moving into government. He is the co-editor of Collaborative Crisis Management: Inter-Organisational Approaches to Extreme Events.

Bynander's work on inter-organisational crisis coordination addresses one of the most practically difficult challenges in modern crisis management: when a crisis spans jurisdictions, agencies, or sectors, whose authority prevails, how do organisations share information in real time, and what governance structures make joint crisis response possible. His comparative research across Nordic, European, and global crisis cases gives his analysis a geographic breadth that most Anglo-American crisis management literature lacks.

35. Daniel Nohrstedt

Professor of Political Science at Uppsala University and co-editor of Collaborative Crisis Management with Fredrik Bynander, Daniel Nohrstedt is a leading researcher on the dynamics of governmental crisis response and the conditions under which public organisations successfully collaborate during extreme events.

His research examines how information flows, authority structures, and intergovernmental relationships affect crisis response quality, drawing on comparative case studies from Sweden, Germany, Denmark, and across Europe. Nohrstedt's analysis of the failure modes of multi-actor crisis response, particularly the tendency for coordination costs to undermine speed and for authority ambiguity to suppress effective action, is among the most empirically grounded work available on why crisis response so often performs worse than preparedness suggests it should.

Category Six: Crisis Preparedness Researchers and Governance Specialists

A distinct cluster of crisis management thinkers focuses specifically on what organisations do before a crisis arrives: how they build governance structures that make effective response possible, how they train leaders and teams for conditions they have not yet experienced, and how they learn from the crises of other organisations without needing to experience them directly. The people in this category represent the preparedness end of the field, where the highest-leverage interventions are available.

36. Amy Edmondson

The Novartis Professor of Leadership and Management at Harvard Business School and Thinkers50's second-ranked management thinker in the world, Amy Edmondson is best known for her research on psychological safety, but her work has profound implications for crisis management that are less widely discussed. Her 2023 book Right Kind of Wrong: The Science of Failing Well examines the conditions under which organisations can build a culture of learning from near-misses, failures, and mistakes.

Edmondson's framework distinguishes between preventable failures that should be avoided, complex failures that emerge from system interactions, and intelligent failures that generate genuine learning. For crisis managers, her research offers the conceptual tools to build organisations that get better at crisis response with each event they experience, transforming what would otherwise be purely destructive events into the raw material of genuine resilience.

37. Helio Fred Garcia

President of the Logos Institute for Crisis and Reputation Management and author of The Agony of Decision: Mental Readiness and Leadership in a Crisis, Helio Fred Garcia brings a distinctive philosophical and psychological lens to crisis leadership. His work focuses on the mental preparation that enables leaders to make good decisions under conditions of extreme uncertainty, time pressure, and emotional intensity.

Garcia argues that the most important crisis leadership skill is not knowledge of procedures or frameworks but the trained capacity to resist the cognitive shortcuts and emotional reactions that lead to poor crisis decisions. His work with military, government, and corporate clients on building this mental readiness translates academic insights from decision science into practical training interventions.

38. Jonathan Shaw

A former British Army Major General and one of the UK's foremost experts on crisis leadership and cyber security, Jonathan Shaw brings military crisis leadership experience that spans the Falklands, Kosovo, and Iraq, alongside his role as the British Army's first Head of Cybersecurity. His work at the intersection of physical crisis and cyber threat is particularly relevant as organisations increasingly face crises that begin in the digital domain.

Shaw's ability to apply military crisis leadership frameworks, with their emphasis on clear command authority, rapid decision cycles, and operational discipline, to corporate crisis management has made him a sought-after speaker and advisor to major organisations preparing for their most severe scenarios. His perspective that crisis leadership is ultimately a practised skill, not an innate one, aligns with the best evidence from both military and corporate settings.

39. Melissa DeLay

Founder and principal of TruPerception, a crisis communications consultancy based in the United States, Melissa DeLay has built her practice around helping clients understand that crisis management is fundamentally about perception management. Her work addresses the gap between how organisations believe they are being perceived during a crisis and how they are actually being perceived.

DeLay's consulting work spans product recalls, executive leadership crises, workplace incidents, and reputation attacks, and her LinkedIn commentary on current crisis events provides practitioners with specific analysis of how real organisations are managing their perception challenges in real time. Her emphasis on the gap between internal and external perception of crisis management performance is among the most practically useful corrective available to leaders who assume they are communicating more clearly than they are.

40. Kathie Kramer Ryan

A crisis communication trainer and consultant operating through KKR Consulting, Kathie Kramer Ryan has spent her career helping organisations develop the spokesperson skills, messaging discipline, and communication infrastructure that allow them to perform well when media pressure is at its highest. Her work focuses on the practitioner skills dimension of crisis communication.

The gap between an organisation's crisis plan and its capacity to execute that plan under real conditions is one of the most consequential and most neglected dimensions of crisis preparedness. Ryan's work directly addresses it through training and simulation, helping organisations discover before a crisis arrives that their designated spokespersons have not been sufficiently prepared for the conditions they will actually face.

41. Donna Boehme

A compliance and ethics specialist and the founder of Compliance Strategists, Donna Boehme works at the intersection of corporate governance, regulatory risk, and crisis management. Her work focuses on the conditions under which organisational compliance failures escalate into full crisis events, and what governance structures can interrupt that escalation.

Boehme's perspective on the relationship between a culture of ethical behaviour and crisis resilience is distinctive: organisations that have built genuine compliance cultures, not performative ones, are consistently better positioned to manage the crises that compliance failures generate. Her LinkedIn commentary on current regulatory and ethics crises is among the most practically focused available from someone with deep governance expertise.

Category Seven: Crisis Communications Practitioners and Reputation Specialists

The final category brings together practitioners who have built careers at the sharp end of crisis communications, advising organisations during the most difficult moments they face and building the skills, structures, and cultures that make their clients more resilient. These are the people who take the call at 11pm when a product recall has been announced, who draft the holding statement that will be read by millions, and who coach the CEO through the media appearance that will determine whether a crisis becomes a turning point or a terminus.

42. Hinda Mitchell

President and founder of Inspire PR Group, Hinda Mitchell is a veteran crisis communications practitioner whose work spans corporate, nonprofit, and government clients. Her commentary in PR Daily's 2026 feature on early warning signs of communications crises reflects her front-line experience of the moments when a problem becomes a crisis and what organisations can and cannot do once that transition has occurred.

Mitchell's emphasis on the importance of ongoing stakeholder engagement before crises, rather than treating communications as something that begins when trouble arrives, reflects a maturity of practice that distinguishes experienced crisis communicators from those who have only handled communications in calm conditions. Her conviction that the best crisis communication is simply good communication practised every day resonates with the best evidence from the field.

43. Anne Marie Malecha

President of Dezenhall Resources and a leading voice on what she calls high-stakes lawfare, the convergence of legal battles with media narratives and public opinion campaigns, Anne Marie Malecha advises senior executives and institutions on how to navigate situations where the crisis is simultaneously legal, reputational, and political.

Her 2025 analysis of how litigation has evolved into a public opinion battle, where every court filing becomes a headline and every deposition a news hook, is one of the most precise analyses available of how the crisis communication landscape has changed in the digital era. Malecha's work at Dezenhall, one of the most respected crisis and conflict communications firms in the United States, gives her a case load that few practitioners can match in terms of stakes and complexity.

44. Jonathan Bernstein

After more than forty years in crisis management and public relations, Jonathan Bernstein of Bernstein Crisis Management is one of the most experienced practitioners in the United States. His book Manager's Guide to Crisis Management provides the foundational skills and knowledge that managers at every level need to handle the crises that inevitably occur in any business or organisation.

Bernstein's perspective is shaped by the full range of crises that organisations face, from product recalls and executive misconduct to cyber attacks and natural disasters, and his work consistently emphasises the importance of having a plan before you need one. His consistent engagement with the field through published articles and commentary that practitioners have relied on for decades makes him one of the most foundational voices in the American crisis management community.

45. Stephanie Craig

President of Craig Communications, one of Canada's leading crisis and issues management consultancies, Stephanie Craig has been advising organisations through major crises for over twenty years. Her work spans both the preparation and response phases of crisis management, and her practice reflects the distinctive features of the Canadian regulatory and media environment.

Craig's work on how organisations should engage with Indigenous communities during crises affecting land, resources, or cultural heritage is an area of growing importance that few crisis communication practitioners address with the depth that it requires. Her contribution to this dimension of the field is distinctive within the North American crisis management community.

46. Phil Hall

Founder and CEO of PHA Group, one of the UK's leading PR and communications firms, Phil Hall has managed some of the most high-profile media crises in the United Kingdom over a career spanning three decades. His work combines strategic communications advisory with the practical media relations skills that determine whether an organisation's message reaches its audiences during a crisis or is overtaken by the media's own narrative.

Hall's perspective on the relationship between crisis management and long-term reputation reflects his understanding that how an organisation is perceived before a crisis is the single most important determinant of how much latitude its stakeholders will extend to it during one. The reputational capital built in normal operations is the primary resource available during a crisis, and organisations that have not built it cannot conjure it under pressure.

47. Eric Dezenhall

Founder and CEO of Dezenhall Resources, one of the most respected crisis management firms in Washington DC, Eric Dezenhall is a genuine contrarian in a field that tends toward consensus advice. His book Damage Control: Why Everything You Know About Crisis Management Is Wrong, co-authored with John Weber, challenges some of the most widely repeated crisis management principles.

Dezenhall argues that in many crisis situations, standard PR advice, including the advice to be transparent, to get ahead of the story, and to apologise, is actively counterproductive. His willingness to take unpopular positions has made him controversial, but his case for a more adversarial and realistic approach to crisis management has influenced how sophisticated clients think about their options when they are most under pressure.

48. Caspar Berry

A former professional poker player turned keynote speaker and risk consultant, Caspar Berry has developed one of the most original frameworks for understanding how leaders make decisions under conditions of high uncertainty and incomplete information. His work draws a direct parallel between the psychology of high-stakes poker decision-making and the cognitive demands of crisis leadership.

Having delivered more than 1,200 talks for global brands including Google, Barclays, and PayPal, Berry's framework has been tested extensively with executive audiences and refined into a practically applicable set of tools for crisis decision-making. His central argument, that the willingness to act under uncertainty is the decisive skill that separates effective crisis leaders from those who wait for information that will never arrive, resonates deeply with practitioners who have been in genuinely difficult situations.

49. Kwame Christian

Founder and CEO of the American Negotiation Institute and host of Negotiate Anything, with over 16 million downloads in more than 180 countries, Kwame Christian brings negotiation science to crisis management in a way that is distinctive and underutilised. His framework, the Compassionate Curiosity Framework, offers crisis leaders a structured approach to the high-stakes stakeholder conversations that every major crisis requires.

Christian's TEDx Talk "Finding Confidence in Conflict," which has been viewed over 500,000 times, distils his core insight that the skills required to navigate crisis conversations are trainable and learnable. His work on how to have difficult conversations without damaging relationships is directly applicable to every phase of crisis management, from the early conversations about risk that most organisations avoid to the post-crisis repair conversations that determine whether trust can be rebuilt.

50. Jonno White

The people on this list are the thinkers. Jonno White is the person you bring in when your leadership team is ready to act on what they say. A Certified Working Genius Facilitator and bestselling author of Step Up or Step Out, which has sold more than 10,000 copies globally, Jonno works with leadership teams to build the culture, communication skills, and team dynamics that make crisis management possible.

He delivers keynotes on conflict, leadership under pressure, and building high-performing teams, and facilitates executive offsites that help leadership teams make aligned decisions on the most difficult questions they face. The conversations that prevent crises and the conversations that contain them are, fundamentally, the same kind of conversations.

Notable Voices We Almost Included

Several important voices in adjacent fields were considered and did not make this final list, not because their work is irrelevant but for specific editorial reasons. Nassim Nicholas Taleb, whose Black Swan framework is foundational to how the field thinks about low-probability, high-impact crises, was considered but is primarily a philosopher and mathematical statistician rather than an applied crisis management practitioner.

George Stephanopoulos, whose 2025 book on presidential crisis decision-making contains valuable insider insights, was considered but is primarily a journalist and broadcaster rather than a crisis management practitioner. Brené Brown, Adam Grant, and Simon Sinek would appear on most leadership lists of this kind. Their work has shaped the broader leadership conversation for over a decade and their contributions are foundational. We deliberately moved past these household names to surface fresher voices who are doing specific work in this field.

Naomi Klein's work on disaster capitalism and crisis exploitation is analytically important but operates at a political and systemic level that is distinct from the practitioner and leadership development focus of this list.

Common Mistakes to Avoid

The first and most consequential mistake organisations make is treating crisis management as a communications function rather than a leadership function. When a crisis arrives, the decisions that determine the outcome are not messaging decisions. They are operational, ethical, and strategic decisions about what the organisation will actually do. The communication of those decisions matters enormously, but the decisions themselves matter more.

The second common mistake is confusing crisis planning with crisis preparedness. A plan is a document. Preparedness is a capability. Most organisations that have been through a serious crisis will tell you that their plan was largely useless, not because it was badly designed but because no one had practised it under conditions of genuine pressure. The organisations that respond most effectively to crises are those that have run tabletop exercises, simulation events, and stress tests that exposed the gaps between the plan and the reality.

The third mistake is underestimating the speed of digital crisis escalation. The crisis communication frameworks that were standard a decade ago assumed that organisations had hours, or at least an hour, to craft a considered response. In 2026, the window is often minutes. Social media analytics, newsroom monitoring, and AI-driven content amplification systems mean that a crisis can go from a single video or tweet to a global media story faster than most organisations' crisis response teams can convene a call.

The fourth mistake is neglecting the internal communication dimension of crisis management. Most crisis management frameworks focus almost exclusively on external stakeholders: customers, media, regulators, and investors. But the internal audience, employees who are simultaneously dealing with the emotional impact of a crisis and being asked to perform at a higher level than usual, is frequently the most important audience to reach and the most neglected.

The fifth mistake is failing to learn from the crisis after it is over. Post-crisis review processes are among the highest-return investments any organisation can make, yet they are often perfunctory, politically charged, or skipped entirely in the rush to return to normal operations. The organisations that emerge genuinely stronger from crises are those that have used the experience to update their understanding of their vulnerabilities, their leadership capabilities, and their communication structures.

Implementation Guide: Taking Action

Building meaningful crisis management capability is not a project with a completion date. It is an ongoing discipline that needs to be embedded into how an organisation operates on a normal day, not bolted on when trouble arrives.

The first step is an honest assessment of where your organisation sits on the spectrum between fully unprepared and genuinely crisis-ready. This means examining not just whether a crisis plan exists, but whether anyone knows where it is, whether it has been reviewed in the past twelve months, and whether the people named in it are still in the roles assumed by the plan. Most organisations that have conducted this assessment honestly have found that their actual preparedness is significantly below what they believed it to be.

The second step is to identify the three most likely crisis scenarios your organisation faces. Not the most dramatic, and not the most catastrophic, but the most probable. For most organisations, these will include a cyber incident, a leadership or misconduct allegation, and a supply chain or operational failure. Designing specific response protocols for your most likely scenarios is far more valuable than designing generic frameworks that cover every possible eventuality with equal superficiality.

The third step is to run a tabletop exercise with your leadership team. A tabletop exercise does not require a major production. It requires a facilitator, a scenario, and two to three hours of honest engagement from the people who would actually be in the room when a crisis happens. The most valuable output of a tabletop exercise is not the updated plan that follows it but the shared understanding among your leadership team of how each person behaves under pressure, where your communication protocols break down, and what decisions your existing authority structures are actually equipped to make.

Jonno White facilitates executive offsite sessions that help leadership teams develop exactly this kind of shared understanding. As a Certified Working Genius Facilitator and host of The Leadership Conversations Podcast with 230 episodes in over 150 countries, Jonno brings the frameworks and facilitation skills to surface the conversations leadership teams need to have before a crisis forces them. Email jonno@consultclarity.org.

The fourth step is to build your crisis monitoring capability. Most crises give some form of early warning signal before they escalate. Social media listening, employee feedback systems, supplier relationship monitoring, and regulatory change tracking are all crisis intelligence systems that most organisations have in some form but rarely integrate into a coherent early warning function.

The fifth step is to build a crisis communications resource in advance. This means identifying your crisis spokespersons and ensuring they have been media trained. It means drafting holding statements for your most likely scenarios. It means establishing the notification protocols that will get the right people on a call within fifteen minutes of a crisis signal being identified.

Frequently Asked Questions

What is crisis management?

Crisis management is the discipline of preparing for, responding to, and recovering from events that threaten an organisation's operations, reputation, financial stability, or stakeholder relationships. It encompasses communications strategy, leadership decision-making, operational continuity, team coordination, and post-crisis learning. It is distinct from crisis communication, which is one component of the larger discipline.

Who are the most influential crisis management thought leaders in the world?

The fifty people on this list represent the most important voices across the full spectrum of crisis management, from corporate communications and academic research to emergency management and geopolitical risk. Practitioners like Melissa Agnes, Edward Segal, and Deborah Hileman have built practitioner frameworks with global reach. Researchers like Tim Coombs, Arjen Boin, and Amy Edmondson have built the theoretical foundations. Systems thinkers like Ian Bremmer, Michele Wucker, and Chris Clearfield are addressing the category of crisis that most corporate frameworks are not yet equipped to handle.

How was this list compiled?

The list was compiled through a structured research process that prioritised genuine contribution to the field over name recognition. Selection criteria included specific published work, credentialled expertise, geographic and disciplinary diversity, and a deliberate preference for voices doing current, original work. The list spans corporate communications, academic research, emergency management, military leadership, digital and cyber crisis, geopolitical risk, and business resilience.

What is the difference between crisis management and crisis communication?

Crisis communication is the practice of communicating with internal and external stakeholders during and after a crisis. Crisis management is the broader discipline that encompasses communication, but also includes the operational, strategic, and leadership dimensions of how an organisation responds to and recovers from a major adverse event. Most organisations that have experienced serious crises report that their communication challenges were symptoms of their management failures, not independent problems.

How do I build crisis management capability in a small organisation?

Small organisations are not exempt from crises, and the gap between their actual preparedness and their assumed preparedness is often larger than in larger organisations. The starting point is identifying your three most likely scenarios, designating clear decision-making authority for each, establishing basic notification protocols, and running a single tabletop exercise with your core leadership team. None of these steps requires specialist staff or large budget.

Can I hire someone to help my leadership team build crisis readiness?

Jonno White works with leadership teams to build the culture, communication skills, and team dynamics that make crisis management possible. He delivers keynotes on leadership under pressure, facilitates executive offsites that help leadership teams practise decision-making in high-stakes scenarios, and runs workshops that strengthen the team foundations that crisis resilience depends on. Jonno White is a Certified Working Genius Facilitator, bestselling author of Step Up or Step Out, host of The Leadership Conversations Podcast with 230 episodes in 150 countries, and a trusted facilitator for leadership teams across Australia and globally. International travel is often far more affordable than clients expect. To discuss how Jonno might support your team, email jonno@consultclarity.org.

What is the most common crisis management mistake organisations make?

The most consistent finding across crisis management research and practice is that organisations confuse having a plan with having a capability. Crises are not paperwork events. They are human performance events, and human performance under pressure degrades without practice. The single most common precursor to poor crisis response is the absence of recent, realistic practice. Organisations that have run tabletop exercises in the twelve months before a crisis consistently outperform those that have not, regardless of the quality of their written plan.

Final Thoughts

The fifty people on this list share a conviction that is more important than any specific framework or methodology they have developed. They believe that organisations can be better. Not just better at surviving crises, but better at anticipating them, preparing for them, learning from them, and emerging from them with the capacity to do more good in the world than they could before the crisis tested them.

That conviction is not naive. The people who study and practice crisis management professionally see organisations at their worst: the cover-ups, the panic, the poor decisions made under extreme pressure, the leaders who collapse when their teams need them most. They have seen what happens when organisations are unprepared. And precisely because they have seen it, they remain committed to the belief that it does not have to happen this way.

Jonno White works with leadership teams who share this conviction. As a bestselling author of Step Up or Step Out and Certified Working Genius Facilitator, he helps leadership teams build the foundation that makes crisis resilience possible: the trust, the communication skills, the shared understanding of how each person behaves under pressure, and the culture of honest conversation that means problems get surfaced before they become crises. The Working Genius framework, completed by more than 1.3 million people globally, is among the most powerful tools available for understanding how your team's natural energies align and where gaps will appear under pressure.
