The Foundation for Execution Velocity

This distinction matters for you because you can have a team that trusts each other, is reliable, and follows through on commitments, but lacks psychological safety. People deliver on tasks but won’t admit confusion about strategy, won’t surface process problems, and won’t challenge assumptions. Trust enables coordination; psychological safety enables learning and adaptation.

Psychological Safety as a Social Resource

Edmondson’s 2024 research with Michaela Kerrissey, published in the International Journal of Public Health, demonstrates that psychological safety functions as a social resource that becomes even more valuable during constraint and uncertainty. [4] Studying healthcare workers during the pandemic, they found that a one standard deviation increase in psychological safety was associated with measurably lower burnout and significantly higher retention, even when people lacked adequate tools or staffing.

Critically, the protective effect was strongest for physicians, women, and people of colour: groups historically less likely to speak up or be listened to. Psychological safety didn’t just help everyone; it particularly helped those facing the greatest barriers to voicing their concerns.

For growth-mandate CEOs, this research has direct implications. Constraint is your reality. You’re not working with unlimited resources, perfect teams, or long runways. You have the budget you have, the team you inherited, and a board expecting visible progress within quarters, not years. In this environment, psychological safety becomes infrastructure, not luxury. It allows you to extract maximum learning and coordination from limited resources.

The Link to Execution Velocity

The connection between psychological safety and execution velocity is direct and measurable. Edmondson’s research shows that when people feel safe speaking up:

• Problems surface earlier, when they’re smaller and cheaper to fix, rather than escalating until they’re impossible to ignore

• Cross-functional coordination improves because teams can be honest about dependencies, constraints, and what they need from each other

• Innovation accelerates because people test ideas rapidly in the open rather than perfecting them in isolation

• Decision quality improves because diverse perspectives are actually voiced in meetings, not just present in the room

• Learning speed increases because people ask clarifying questions rather than nodding and figuring things out alone [5]

For a CEO looking to accelerate growth, each of these directly affects your ability to execute. Slow problem detection means you’re behind market shifts. Poor coordination means initiatives take longer and require more management overhead. Slow iteration means you’re still testing strategies that should have been killed months ago. Filtered decision input means you’re missing critical information. Slow learning means your organisation can’t adapt to what customers are telling you.

Six Critical Misconceptions

In their May 2025 Harvard Business Review article, Edmondson and Kerrissey identify six misconceptions that cause leaders to implement psychological safety incorrectly [6]:

1. It’s not about being nice to avoid arguments. Productive disagreement and constructive feedback are essential, not threats to psychological safety. The goal is honest debate, not comfortable consensus.

2. It’s not a personality trait. Psychological safety is a feature of the team environment that leaders create through their behaviours, not a characteristic of certain people.

3. It’s not the opposite of high performance. Research consistently shows teams with high psychological safety have high standards and get better results. The combination of safety and standards creates excellence.

4. It can’t be mandated by policy. Rhode Island’s 2024 Workplace Psychological Safety Act demonstrates this misconception. Telling people they must have psychological safety “or else” doesn’t create it. It’s built through repeated interactions, not declarations.

5. It doesn’t require consensus. Psychological safety means all voices are heard before decisions are made, not that everyone must agree with every decision.

6. It doesn’t have to start at the top. While CEO behaviour matters enormously, any leader at any level can build psychological safety within their team.

For CEOs, the third misconception is particularly important to internalise. Some leaders resist creating psychological safety because they fear it will lower performance standards or make the organisation “soft.” Edmondson’s research shows the opposite: the combination of high psychological safety and high standards creates the conditions for peak performance.

Three Leadership Behaviours That Create Psychological Safety

Edmondson’s work identifies three specific, observable behaviours leaders can practise to build psychological safety [7]:

Frame the work: Make it clear that the work involves uncertainty, complexity, and interdependence. Emphasise why everyone’s input matters and that you’re working on problems where no one has all the answers. This creates the context where speaking up is necessary, not optional.

Invite input genuinely: Ask good open-ended questions, acknowledge your own knowledge gaps, and create structures where speaking up is normalised rather than heroic. This moves from “you can speak up if you really need to” to “we expect everyone to contribute observations and questions.”

Respond productively: Thank people for speaking up, especially when the news is bad. Separate the messenger from the message: if someone brings you a problem, respond to the problem, not to the person. Sanction those who shoot the messenger, not those who deliver difficult messages.

These behaviours are observable and measurable. A CEO serious about building psychological safety can track how frequently they do each, get feedback from their team on how these behaviours land, and adjust based on results.

Why This Matters for Growth

Edmondson’s recent work emphasises that psychological safety enables learning behaviour, and learning behaviour drives organisational performance. The connection is direct: individual learning doesn’t automatically translate to organisational learning. Organisations improve when processes change, innovations are implemented, and new approaches are scaled across teams. This requires people to share what they’re learning, surface problems, ask for help, and experiment, all behaviours that require psychological safety. [8]

For you, this creates a clear strategic linkage. Speeding up growth requires organisational learning at speed. You need rapid iteration on go-to-market approaches, faster problem-solving across functions, the ability to pivot when strategies aren’t working, and the collective intelligence of your organisation focused on what’s blocking growth. None of this happens if your team is self-censoring because interpersonal risk feels too high.

As Edmondson stated at UNLEASH World 2025, “high psychological safety means a high learning quotient.” Teams that learn quickly have clear goals, necessary expertise, adequate resources, and sufficient effort, plus the candour to speak up about what they see and know. Without that last piece, the other organisational capabilities don’t translate to performance[^9].

Timothy Clark’s Four Stages: A Diagnostic Framework

While Edmondson’s research establishes what psychological safety is and why it matters, Timothy Clark’s framework provides a diagnostic tool for leaders: Where is your team stuck? What specific behaviours will move you to the next stage?

Clark, CEO of LeaderFactor and author of The 4 Stages of Psychological Safety, developed his framework from a recognition that psychological safety develops progressively, following the natural pattern of human needs in social settings. His four stages: inclusion safety, learner safety, contributor safety, and challenger safety, build cumulatively. You can’t skip stages, and weakness at an early stage will limit what’s possible in later stages. [10]

The Framework: Two Dimensions, Four Stages

Clark’s model is built on two dimensions: respect and permission. Respect is the acknowledgement that people deserve to be included based on their humanity. Permission is the leader’s active invitation for people to participate, learn, contribute, and challenge. Psychological safety increases as both respect and permission increase through the four stages. [11]

Stage 1: Inclusion Safety satisfies the basic human need to connect and belong. At this stage, people feel welcome, valued, and that they have a place on the team. This begins with an unconditional offering of respect: everyone deserves it simply for their humanity, not their credentials, position, or performance.

For growth-mandate CEOs, this foundational stage has immediate implications. If you’ve inherited a team with history and tenure, subtle hierarchies may exist: original employees versus newer hires, technical experts versus business generalists, headquarters versus field offices, executives versus individual contributors. These create fault lines where people psychologically exclude themselves or are excluded by others. Growth requires everyone contributing, not just the inner circle.

Clark’s research shows that children intuitively understand the importance of inclusion, yet adults find ways to justify exclusion, often to compensate for their own insecurities. The pattern starts with leaders who are more concerned with being right than creating an environment where everyone can contribute, then cascades through the organisation. [12]

Stage 2: Learner Safety is where people feel safe to engage in the learning process: asking questions, giving and receiving feedback, experimenting, and making mistakes. Clark emphasises that you can’t demand learning; you inspire it by creating a supportive environment where people are seen as works in progress, and mistakes are part of development, not evidence of incompetence. [13]

This stage is critical for execution velocity. When people fear looking incompetent, they avoid asking clarifying questions about priorities or strategy. They don’t surface confusion. They don’t admit when they don’t know how to do something. The result is slower execution because people figure things out in isolation rather than learning collectively.

Clark observes that learner safety is rarely present without inclusion safety: if you don’t feel you belong, you won’t risk looking ignorant. But the reverse isn’t automatic. Some teams have strong inclusion but punish mistakes, creating a comfortable but stagnant environment where people won’t try new approaches.

Stage 3: Contributor Safety is when people feel safe using their skills and making meaningful contributions. Individuals have both the confidence and permission to do the work, share ideas, and add value in their areas of expertise. This satisfies the need to make a difference and see that your contributions matter. [14]

For leaders, this is where organisational capacity lives. If people have ideas for improving processes, accelerating deals, or removing bottlenecks but don’t voice them because they fear rejection or dismissal, you’re losing significant capacity. Contributor safety isn’t about people feeling good; it’s about extracting insights and improvements they’re seeing but not sharing.

Organisations often struggle here because they confuse activity with contribution. People are busy, working hard, but not feeling safe to offer real input on how work could be done better. The CEO’s signal, whether they genuinely want input or just want compliance, determines whether contributor safety develops.

Stage 4: Challenger Safety is where people feel safe to question the status quo, challenge assumptions, and suggest the organisation or team should change direction. Clark describes this as “democratising innovation”: making it safe for anyone to challenge, not just senior people[^15].

This is the most psychologically risky stage and the most valuable for growth. If your strategy isn’t working, you need people close to customers, markets, and operations to challenge it. If your processes are creating bottlenecks, you need the people living in those processes to surface it. If your executive team is misaligned, you need someone to name it.

Clark’s research shows that challenger safety is rare. Most organisational cultures tolerate challenge from a few senior voices but punish it from others. The result is that the people with the most current information, frontline employees, newer team members, specialists in specific domains, self-censor when they see problems. Leadership gets filtered feedback and makes decisions on incomplete information. [16]

Using the Framework Diagnostically

The practical power of Clark’s framework is diagnostic. Rather than thinking “we need more psychological safety” in the abstract, you can assess: At which stage is my team stuck? Where is the foundation weak?

For a growth-mandate leader, this creates a clear path forward. If your executive team won’t challenge your strategy (stage 4), the problem might not be at stage four; it might be back at stage one or two. People who don’t feel genuinely included won’t take the risk of challenge. People who fear looking ignorant won’t contribute bold ideas.

This suggests a sequencing strategy:

1. Start with the foundation. Make sure people feel they genuinely belong to the team and aren’t subtly excluded based on background, role, or tenure.

2. Create a culture of learner safety by responding well when people admit confusion, ask questions, or make mistakes. Your response in these moments programmes the culture.

3. Build contributor safety by implementing team ideas and making it clear that contributions matter and lead to change.

4. Only then develop challenger safety, where people feel safe to tell you what’s not working. This requires the previous three stages as a foundation.

Clark emphasises that these stages are cumulative. You can’t skip ahead. An organisation with weak inclusion safety won’t develop genuine challenger safety, even if the CEO invites challenge. People won’t take the risk because the foundation isn’t there. [17]

Brené Brown’s Research: The Leader Must Go First

While Edmondson’s research shows that psychological safety enables performance and Clark’s framework provides a diagnostic for building it, Brené Brown’s work on vulnerability and courage addresses a critical question: What must leaders personally do to create psychological safety? Her answer, grounded in two decades of research, is both simple and difficult: leaders must model the very behaviours they want to see.

Brown, a research professor at the University of Houston and Executive Director of the Centre for Daring Leadership at BetterUp, has studied vulnerability, courage, shame, and empathy across hundreds of organisations. Her central finding: the behaviours that create trust and connection, being honest about uncertainty, admitting mistakes, asking for help, feel risky precisely because they expose us to potential judgement. [18]

The Vulnerability Paradox for Leaders

Leaders face this tension acutely. They’re expected to have answers, project confidence, and appear in control. Boards, investors, and teams look to CEOs to provide direction and certainty. Yet the very behaviours that create psychological safety require stepping out of that armour: admitting “I don’t know,” acknowledging mistakes, asking for input when you’re uncertain.

Brown defines vulnerability as uncertainty, risk, and emotional exposure. It’s not weakness or oversharing; it’s the willingness to show up when you can’t control the outcome. Her research, particularly in Dare to Lead (2018) and her 2025 book Strong Ground, emphasises that courage and vulnerability are inseparable. You cannot get to courage without “rumbling with vulnerability,” Brown’s term for engaging with the discomfort rather than avoiding it. [19]

For you, this creates a specific dilemma. You were hired to appear confident and capable. Your board expects you to have a plan. Your team is looking for decisive leadership. Yet creating the psychological safety that enables execution velocity requires you to be honest when strategy isn’t working, to say “I need your perspective on this,” and to acknowledge when you’ve made a hiring or strategic mistake.

The Armour Leaders Use

Brown’s research identifies the “armour” leaders use to avoid vulnerability: perfectionism (never admitting mistakes), numbing (avoiding difficult emotions or conversations), being the knower instead of the learner, using cynicism to avoid disappointment, and leading from hurt and fear rather than values. This armour feels protective in the moment but prevents the connection and trust necessary for high-performing teams. [20]

When leaders armour up, teams follow. If the CEO never admits uncertainty, the executive team won’t either. If the executive team doesn’t model vulnerability, middle managers won’t. The pattern cascades: each level protects itself by projecting certainty, and the organisation loses the ability to be honest about reality.

The alternative Brown proposes is daring leadership: being willing to have difficult conversations, making values-based decisions even when uncomfortable, giving and receiving honest feedback, and practising self-awareness and self-compassion. This isn’t about being soft; it’s about being brave enough to be honest. [21]

Four Skill Sets of Daring Leadership

Brown’s research with organisations globally has identified four skill sets of daring leadership, all of which both require psychological safety to practise and help create psychological safety in teams [22]:

Rumbling with vulnerability: Recognising when you’re in situations with uncertainty and risk, and choosing to engage rather than armour up. This means naming when you don’t have all the answers, asking for help, and being honest about mistakes.

Living into values: Clarifying what matters most to you as a leader and organisation, then practising those values through observable behaviours, especially when it’s hard. If one of your values is “learning,” do you respond to mistakes as learning opportunities or as failures to be punished?

Braving trust: Using the elements of trust: boundaries, reliability, accountability, vault (keeping confidences), integrity, non-judgement, and generosity, to build and repair trust with teams. Each element is a behaviour you can practise and be measured on.

Learning to rise: How you respond when you fail, fall, or get things wrong. Do you blame others and double down? Or do you own the mistake, learn from it, and adjust? Your pattern here programmes how your team handles failure.

Each skill set models behaviours that create psychological safety. When leaders rumble with vulnerability, they demonstrate it’s safe to be uncertain. When they live by values despite discomfort, they show that difficult conversations are expected. When they build trust through reliability and accountability, they lay the foundation for risk-taking to feel safe. When they rise from failures with learning rather than blame, they signal mistakes are part of growth.

Leadership in Times of Uncertainty

Brown’s 2025 book Strong Ground addresses leadership specifically in times of deep uncertainty, the exact context growth-mandate CEOs face. When you’ve been brought in because growth has stalled and previous strategies stopped working, you’re operating in uncertainty by definition. You’re trying new approaches. You’re diagnosing problems. You don’t have all the answers yet.

Brown argues that when bluster and hubris are increasingly framed as acceptable forms of leadership, we need to reclaim courageous leadership grounded in connection, discipline, and accountability. This means having the courage to say, “I don’t know what will work, but here’s what we’re going to try and learn.” It means being honest with your board about progress and setbacks. It means telling your team “we got this wrong and we’re pivoting.” [23]

Why This Is Hard, and Why It Matters

A critical insight from Brown’s work: leaders significantly underestimate the courage required to create psychological safety. Inviting people to challenge your thinking feels threatening. Admitting you made a hiring mistake feels like exposing failure. Asking your board for patience while you figure out what’s broken feels risky.

Yet these are precisely the behaviours that create the environment where others can be honest with you. If you need your team to surface pipeline risks, admit when they’re confused about strategy, and tell you when initiatives aren’t working, you have to show them it’s safe by doing those things yourself first.

Brown’s research on shame and empathy illuminates why psychological safety is hard to sustain. When leaders experience shame about not knowing, about mistakes, about the organisation’s struggles, the instinct is to protect the ego by shutting down feedback, blaming others, or projecting invulnerability. This destroys psychological safety instantly. [24]

The alternative is shame resilience: recognising shame when it shows up, reaching out rather than pulling back, and speaking about it rather than letting it silently drive defensive behaviour. This allows you to stay in the conversation even when you feel exposed.

The Practical Challenge

Brown’s work with CEOs globally through the Centre for Daring Leadership reveals a consistent pattern: the organisations that outperform during uncertainty are led by people willing to say “we’re navigating this together” rather than “I have all the answers.” Her TED talk “The Power of Vulnerability,” with over 60 million views, resonates because people recognise this truth, the leaders they remember, trust, and follow are the ones who were brave enough to be real. [25]

The practical challenge Brown identifies is that vulnerability feels dangerous precisely because it is risky. There’s no guarantee of how people will respond. But the research is clear: when leaders take the first risk by being vulnerable, it creates permission for others to do the same. Over time, this builds the psychological safety where honest, difficult, constructive conversations become normal rather than exceptional.

How These Frameworks Connect

Three researchers, three frameworks, one convergent insight: psychological safety is infrastructure for execution, not a cultural luxury. Understanding how their work connects helps CEOs build a practical approach.

Edmondson establishes the why: Psychological safety is a measurable condition that enables learning behaviour and performance, particularly under constraint. Her research demonstrates that teams with high psychological safety execute faster, learn more quickly, and achieve better outcomes, especially when resources are limited and stakes are high.

Clark provides the diagnostic: His four-stage framework helps you assess where your team is stuck and what specific behaviours will move them forward. Rather than vague directives to “build psychological safety,” you can identify: We’re weak at stage two (learner safety). We need to respond better when people admit they don’t know something.

Brown reveals the leadership requirement: Leaders must model vulnerability to create the safety they want to see. You can’t ask your team to admit mistakes, surface problems, and challenge assumptions if you’re not doing those things yourself. Leadership vulnerability isn’t optional; it’s the mechanism that creates organisational psychological safety.

Where They Converge on CEO Action

All three researchers emphasise that creating psychological safety is not about making one inspiring speech or implementing a new policy. It’s built through repeated interactions where leaders demonstrate, through their actual behaviour in real moments, that interpersonal risk-taking is safe.

The convergence suggests a clear action path for CEOs:

Start with your executive team. Use Clark’s framework to diagnose where you are. Do people feel genuinely included? Are they comfortable admitting confusion or mistakes? Do they contribute ideas freely? Do they challenge your thinking and each other’s? Be honest about which stage you’re stuck at.

Examine your personal responses using Brown’s lens. When someone admits a mistake, do you thank them or focus on the failure? When someone says “I don’t know,” do you create a learning space or signal they should have known? Your reflexive responses in these moments are programming your culture faster than any values statement.

Practise Edmondson’s three behaviours consistently: frame the work by acknowledging uncertainty, invite input by asking genuine questions where you don’t have answers, and respond productively to difficult news by thanking the messenger before addressing the message.

Focus on critical execution paths. Identify where execution is stalling, typically in cross-functional coordination, strategic decision-making, or problem escalation. Use psychological safety as the diagnostic: What’s not being said? What risks are people seeing but not surfacing? The gap between what people know and what they’re saying is the psychological safety gap you need to close.

Recognise that safety and standards go hand in hand. As Edmondson emphasises throughout her work, the goal isn’t a comfortable consensus where everyone agrees. The goal is honest, constructive disagreement that surfaces problems early and accelerates solutions. High psychological safety combined with high standards creates peak performance.

The Integration Challenge

Integrating these frameworks requires recognising that they address different aspects of the same system. Edmondson’s work helps you understand what psychological safety is and why it matters for execution. Clark’s framework helps you diagnose where you are and what to work on next. Brown’s research helps you understand what you personally must do to model the behaviours you want to see.

The practical challenge is that each framework requires something difficult. Edmondson asks you to measure and acknowledge gaps in psychological safety on your teams. Clark asks you to start at stage one even when you want to jump to stage four. Brown asks you to model vulnerability even when it feels risky and exposing.

But the convergent promise is that this work directly impacts your ability to restart growth. Organisations with high psychological safety surface problems faster, coordinate across boundaries more effectively, iterate on strategy more rapidly, and adapt to market feedback more quickly. Each of these capabilities translates to competitive advantage and execution velocity.

What You Can Do This Week

The research is clear, but research doesn’t speed up growth; action does. Here’s what you can do in the next week to begin building psychological safety as execution infrastructure:

1. Assess your executive team using Clark’s four stages. In your next staff meeting, have an explicit conversation: Where are we in our psychological safety journey? Do people feel genuinely included and valued? Are we comfortable admitting what we don’t know? Do we freely contribute ideas even when they challenge current thinking? Can we challenge each other’s assumptions and the CEO’s thinking productively?

Don’t expect immediate honesty in this conversation; a lack of psychological safety means people won’t be honest about it. But watch behaviour over the following weeks. Are people speaking up? Are they surfacing problems? Are they challenging ideas or just nodding?

2. Audit your responses to vulnerability. For the next week, track every time someone on your team admits they don’t know something, surfaces a problem, or makes a mistake. How did you respond in the moment? Did you thank them for speaking up? Did you ask curious questions? Or did you focus on the gap, express frustration, or move immediately to fixing rather than understanding?

Get feedback from someone you trust: your COO, your executive coach, a board member who observes your meetings. Ask them: “When people bring me problems or admit mistakes, how do I come across? Do I make it feel safe or risky?”

3. Test Edmondson’s three behaviours in a high-stakes meeting. Choose one important meeting this week, perhaps a board meeting, a strategic planning session, or a cross-functional problem-solving meeting. Explicitly practise:

• Frame the work: Open by naming what’s uncertain, complex, or interdependent about what you’re discussing. Say explicitly, “I don’t have the answer here, and I need everyone’s thinking.”

• Invite input: Ask genuine questions you don’t know the answer to. Instead of “Does everyone agree with this approach?” ask “What concerns do you have about this approach? What might we be missing?”

• Respond productively: When someone voices a concern or challenge, say “Thank you for raising that” before you address the content. Visibly appreciate the courage to speak up, not just the quality of the idea.

Notice what happens. Does the conversation change? Do you get different input? Do quieter people speak up more?

4. Identify one critical execution bottleneck and diagnose it through a psychological safety lens. Choose one area where execution is consistently slower than it should be, perhaps monthly business reviews surface problems too late, or cross-functional projects keep stalling, or strategic initiatives don’t get honest feedback until they’ve already failed.

Ask yourself: What’s probably not being said? What do people likely know that they’re not voicing? What would help us execute faster if people felt safer speaking up?

Then create a low-stakes way to test whether psychological safety is the issue. Perhaps a one-on-one conversation where you explicitly invite honesty: “I know this project isn’t moving as fast as we need. What are we not talking about that’s slowing us down?”

5. Model one specific vulnerability with your executive team. Choose something real but bounded: a decision you’re unsure about, a skill gap you have, a mistake you made. Name it explicitly: “I’ve been thinking about our Q2 strategy, and honestly, I’m not confident we have the right approach. I need your help thinking through this differently.”

Watch what happens. Does it create space for others to be honest about their own uncertainties? Does the conversation become more real and useful?

This feels risky because it is risky. But as Brown’s research shows, when leaders take the first step into vulnerability, it creates permission for the organisation to follow.

The Key Question

The research from Edmondson, Clark, and Brown converges on a fundamental choice every CEO must make: Do you want an organisation that tells you what you want to hear, or one that tells you what you need to know?

If growth has stalled, the status quo isn’t working. Restarting growth requires seeing reality clearly, adapting quickly, and leveraging the collective intelligence of your organisation. None of this happens if people are self-censoring because interpersonal risk feels too high.

Psychological safety isn’t about creating comfort or avoiding difficult conversations. It’s about creating the conditions where the most important, most difficult, most necessary conversations can actually happen. Where problems surface when they’re small. Where people coordinate honestly across boundaries. Where bad strategies get challenged before they waste months and millions.

Edmondson’s research proves it enables performance. Clark’s framework shows you how to build it progressively. Brown’s work reveals that you must model the vulnerability you want to see.

The question is whether you’ll do the work to build it, starting this week, in your next meeting, with your next response when someone tells you something difficult.

Because in six months, your organisation will be either more honest or more guarded than it is today. That choice is being made right now, in how you respond when someone admits they don’t know, surfaces a problem, or challenges your thinking.

Choose wisely. Your execution velocity and your ability to restart growth depend on it.
