Most organizations trying to make a significant leadership shift can describe exactly what they’re after. Less reactive, more strategic. Less siloed, more collaborative. Capable of driving today’s results while leading tomorrow’s transformation. The desired “From-To” is rarely the mystery.
What’s harder to see is why it doesn’t happen. Why capable, motivated leaders who genuinely want to change end up back where they started, and why the organization that invested in their development ends up wondering what it got for the effort.
Leadership transformation stalls for three reasons. Most development approaches address none of them.
The first obstacle: hidden commitments that quietly defeat the commitment to change
Robert Kegan and Lisa Lahey, whose research at Harvard forms the foundation of our work at TDE—and who co-founded TDE alongside Claire Lee and me—spent years studying why people don’t change even when they sincerely want to. What they found: in most cases, the obstacle isn’t resistance or lack of commitment. It’s competing commitments: things the leader is protecting, often without knowing it, that quietly work against the very change they say they want to make.
A leader who wants to be more empowering may have an equally genuine commitment to maintaining high standards and has unconsciously concluded that delegating means watching things go wrong. A leader who wants to be more transparent may be just as committed to not appearing uncertain in front of their team. These aren’t character flaws. They’re deeply human protective mechanisms that operate largely below the level of conscious awareness.
This is why telling leaders what to do differently rarely works. The gap between knowing and doing isn’t a knowledge problem. It’s a commitment problem. And standard development—workshops, coaching, feedback—is almost never designed to surface it.
The second obstacle: knowing what's in the way, but never finding out if it's actually true
Even when development is sophisticated enough to surface competing commitments, there’s a second obstacle: the assumptions underneath them never get tested.
Every competing commitment rests on a big assumption: a belief about what will happen if the leader actually changes. “If I delegate, things will go wrong.” “If I’m transparent about uncertainty, I’ll lose credibility.” “If I challenge the strategy, I’ll be seen as not a team player.” These assumptions feel like facts. They’ve rarely been examined, and almost never deliberately tested.
This is the gap where most development stalls. A leader can gain genuine insight into their competing commitments, name the assumptions underneath them, and still not change because the assumptions have never been run against reality. Until they are, the competing commitments hold. The “From” persists.
What’s needed isn’t more insight. It’s a structured way to design real experiments—specific behavioral changes, tried in actual work—that put the assumptions to the test. When a leader discovers that delegating didn’t produce the disaster they expected, or that transparency didn’t cost them credibility, the assumptions loosen. The competing commitments lose their grip. Change becomes possible in a way that insight alone never produces.
The third obstacle: the social environment leaders return to
Even when a leader surfaces their competing commitments and begins testing the assumptions beneath them, there’s a third obstacle waiting: the social environment they work inside. The norms, expectations, and relational dynamics of that system exert a constant gravitational pull. If those around them haven’t shifted, the pressure — subtle and usually unspoken — is to stay the same. Old patterns get reinforced. New behaviors fade.
This is the mechanism behind the experience almost every organization has had: leaders come back from a program energized and committed, and six months later, not much has changed. The real explanation isn’t the program or the leaders. It’s the social environment.
Development that happens to individuals in isolation produces individual insight. It rarely produces organizational change because it was never designed to change the system that behavior lives inside.
The solution: developing leaders together, in real work, in a way that addresses all three obstacles simultaneously
Here is the insight that drives everything we build at TDE: the way your leaders develop together is the way they will lead together. That’s not a metaphor. It’s a design principle.
Most leadership development treats the peer group as a delivery format. We treat it as the mechanism of change. The social environment of development isn’t a feature of our system. It is the system.
When leaders develop in peer cohorts—grounded in the real challenges they’re already facing—the cohort becomes a new kind of social environment: one defined by honest challenge, mutual support, and shared accountability. In that environment, all three obstacles get addressed at once.
The competing commitments that keep people stuck begin to surface because the social environment creates the conditions where it’s safe, and necessary, and supported to look there. The assumptions underneath those commitments get tested because the developmental work is embedded in real work from the start, and peers hold each other accountable for the experiments they’ve committed to run. And the social environment itself begins to shift because the cohort is already modeling the norms, the transparency, and the accountability that the organization is trying to build.
At scale: individual change becomes cultural change
When whole populations of leaders develop this way together, something larger happens. The developmental environment doesn’t stay contained in the program. It spreads. Leaders who have made the shift don’t just model the new way of working. They normalize it. The developmental environment becomes the organizational environment. The culture the organization has been trying to build starts to take hold, not because it was mandated, but because the people who lead the organization are already living it.
The From-To shift accelerates. It scales. And it sticks in a way that individual development simply cannot produce.
Across the organizations we’ve worked with, what surprises leaders most isn’t that it works. It’s how fast it works. Population-level shifts in how leaders think, communicate, and hold each other accountable happen in months, not years.
