The Foundation of Everything
I spent twenty-four years in the British Army, and if there’s one thing I learned it is that trust isn’t optional for leaders. It is the foundation and without it you’re just managing compliance.
Patrick Lencioni understood this when he placed trust at the base of his pyramid in ‘The Five Dysfunctions of a Team’. Every other element, fear of conflict, lack of commitment, avoidance of accountability, inattention to results, they all come from an absence of trust. You cannot fix the higher-level problems until you address the foundation and I have seen this play out countless times. Teams that don’t trust each other don’t get much done. People don’t speak up, they avoid difficult conversations or any form of challenge, and ultimately fail to hold each other accountable. Performance suffers even when the team is highly skilled because it is built on a foundation of sand.
Most people know that trust matters. Leaders talk about it all the time, include it in their values statements, and nod seriously when someone mentions it. Yet when I ask them how they actually build it, the answers I get are a little bit vague.
“Be authentic.”
“Build psychological safety.”
“Be a compassionate leader.”
“Care about people.”
“Treat people the way you want to be treated yourself.”
All true, but not particularly useful when you’re standing in front of a team wondering why they won’t be honest with you.
That’s where the Trust Equation comes in. It’s one of the most practical frameworks I’ve encountered for understanding what trust actually is and how to build it in a deliberate way. Originally developed by David Maister, Charles Green and Robert Galford, it breaks trust down into measurable components, not vague concepts but things you can observe, assess and improve.
The equation looks like this:
Let’s break down what that means in practice.
Credibility: Do You Know What You’re Talking About?
Credibility is about competence. It’s the “do they know their stuff?” question. As I promoted into more senior roles, I didn’t suddenly become more knowledgeable overnight. What changed was the expectation and my team looked to me for answers, and if I didn’t have them, or worse, if I bluffed my way through, trust evaporated quickly.
Credibility is not about knowing everything. It’s about knowing your domain well enough that people believe you when you speak. In the Army, this came from experience, repeated practice under pressure and an understanding that some things were outside of my expertise.
I’ve seen credibility challenged in organisations when leaders try to be experts in everything, thinking that it is a weakness not having all of the answers. Know where your expertise sits, and respect the expertise of others.
Reliability: Do You Do What You Say?
This one seems obvious, yet it’s where most leaders get it wrong. Reliability is about consistency between words and actions. If you say you’ll do something, do you actually do it?
I had a former boss who consistently arrived late to everything, rarely read the emails I sent and only engaged with projects when deadlines were already looming. They meant well and genuinely cared about the work. The difficulty was that you couldn’t rely on them to do what they said they would. Their own administrative chaos meant that by the time they finally got involved, decisions had to be rushed and things had to be reworked to meet their standards. After a while, I stopped expecting them to follow through because their unreliability created more problems than it solved.
Reliability builds through small, repeated actions. Turning up on time. Following through on commitments. Doing the unsexy admin work that no one notices until it’s not done. People learn they can depend on you, and that dependability becomes the bedrock of trust.
If you’re not reliable, nothing else in the trust equation matters. You can be the most credible, personable leader in the world, but if people can’t rely on you, there is no trust.
Intimacy: Can People Be Honest with You?
Intimacy isn’t about being friends with your team. It’s about psychological safety, the degree to which people feel they can be open, vulnerable and honest without being judged for it.
This is what Lencioni calls vulnerability-based trust, the willingness to admit weaknesses, mistakes and fears without worrying about being used against you. Without intimacy, teams never progress and remain stuck in what looks like professionalism but is actually self-protection.
In the Army, this dictated whether soldiers would tell me the truth about problems. If they only ever reported good news, or if they sugar-coated the truth, I knew trust was low. Real intimacy meant soldiers felt safe bringing me bad news, admitting mistakes or challenging my thinking when they thought I was wrong.
One of the best compliments I ever received was from an officer cadet who got themselves into a bit of a mess and I had given a bit of a ‘disappointed Dad chat’. He said, “I knew you’d understand, Sir, you always do.” That wasn’t because I was soft, far from it. It was because I’d shown repeatedly that honesty wouldn’t be weaponised against them and mistakes were learning opportunities and things we solved together.
Building intimacy requires consistency. It means not shooting the messenger and listening without interrupting. It means responding to vulnerability with respect, and not being judgemental. Leaders who get this right create environments where people speak up early, problems surface before they become crises and teams function at a much higher level.
Self-Orientation: Whose Interests Are You Serving?
This is the denominator in the equation, which means it works differently. High self-orientation divides trust. Low self-orientation multiplies it.
Self-orientation is: when you make decisions, whose benefit are you thinking about? Yours, or theirs?
I’ve worked with leaders who talked repeatedly about “caring for people,” but when push came to shove, they took a political stance, their decisions always protected their own reputation, career or comfort. I noticed and I did not trust them!
The best leaders I’ve known, the ones people would follow anywhere, had one thing in common. You never doubted they put the team first. They got their hands dirty with the team, they absorbed blame publicly and gave credit privately, they made decisions that were right for the organisation and the people, even when those decisions cost them personally.
It is important to note that low self-orientation doesn’t mean you ignore your own needs. It means that when you’re in your leadership role, your focus is genuinely on those you’re leading, not on yourself. People can sense the difference and it’s not something you can fake.
Bringing It Together
The beauty of the Trust Equation is that it shows you where to focus. If credibility is low, invest in your professional development. If reliability is the issue, get better at doing what you say you will do. If intimacy is low, work on creating psychological safety. If self-orientation is high, check your motives.
Early in my career, I thought leadership was about having the answers. I focused heavily on credibility, learning everything I could, proving I was competent. I was also laser focused on promotion so perhaps my self-orientation was a little high. Soldiers respected my knowledge and ability, but I don’t think they fully trusted me.
So the problem wasn’t credibility. It was intimacy and self-orientation. I was so focused on being seen as competent that I created distance, didn’t invite challenge, didn’t admit uncertainty. On reflection, perhaps people sensed I was more interested in protecting my reputation than genuinely serving them.
Practical Application:
If you want to assess your own trustworthiness, here are some questions worth sitting with:
Credibility:
• Do people believe I know what I’m talking about in my area of responsibility?
• Am I willing to admit when something is outside my expertise?
• Do I invest in staying current and competent?
Reliability:
• Do I consistently do what I say I’ll do?
• How often do I make commitments I can’t keep?
• What would my team say about whether they can depend on me?
Intimacy:
• Do people feel safe being honest with me?
• When did someone last challenge my thinking or admit a mistake without fear?
• How do I respond when people bring me bad news?
Self-Orientation:
• When I make decisions, whose benefit am I really thinking about?
• Would my team say I put them first, or myself?
• How often do I make choices that protect my comfort over their needs?
The answers to these questions tell you where trust is strong and where it’s fragile. Trust is built through hundreds of small decisions, made consistently over time.
A Final Thought:
Trust is the currency of leadership. You can have all the authority in the world, but if people don’t trust you, they’ll comply when you’re watching and disengage the moment you’re not.
The Trust Equation gives you a useful tool that shows you what to pay attention to and where to invest your effort. Use it honestly, and you’ll build a reputation for being someone people can genuinely trust.
That’s what leadership is really about.
Reflective Questions:
- Which element of the trust equation (credibility, reliability, intimacy, self-orientation) is currently your strongest? Which needs the most attention?
- Think of a leader you deeply trust. How do they score across all four components?
- When was the last time you made a decision that cost you personally but benefited your team? What did that teach you about self-orientation?
- If your team were asked anonymously whether they could be completely honest with you, what would they say? What does that tell you about intimacy?
- How often do you make commitments you struggle to keep? What would change if you committed less but delivered more consistently?
