Three things I got wrong building technology organizations in banking.
25 years across defense intelligence, capital markets, and financial services. Three structural misreads that cost real people real consequences.
MISTAKE 1: I confused delivery speed with organizational health.
I built teams that shipped. On time, on budget. I rewarded velocity, celebrated go-lives, and quietly moved aside the people who raised concerns.
I thought it was high-performance culture.
What it actually was: I had filtered out the people most likely to tell me something important. At least two significant platform failures I experienced had predecessors — people who saw them coming and said so. I had built a culture where that signal could not reach me.
That is not a performance culture. It is a culture of informed silence.
MISTAKE 2: I protected my team from politics instead of preparing them for it.
I absorbed the friction above my teams so they could focus on building. I was proud of it.
What it actually was: I was building technically excellent people who were institutionally naive. When they moved into senior roles I had sponsored, they encountered the political reality I had shielded them from — and had no framework for navigating it.
Leadership development that only addresses craft is incomplete. I learned this too late for the people it cost.
MISTAKE 3: I waited too long to have the honest conversation.
When I knew a program was in structural trouble — the kind that could not be fixed by adding resources or adjusting scope — I kept working it internally. I believed escalating without a solution was weakness.
What it actually was: I was protecting my own self-assessment at the expense of people who deserved to know sooner. The teams working those programs stayed late and carried the weight of saving something I privately understood might not be salvageable.
The delay did not protect the outcome. It protected my discomfort.
Executives who cannot say “I don’t know how to fix this and I need help” are not strong. They are expensive.
These three mistakes recur across every leadership context I have seen. Different organizations, different stakes — the same structural failures.
What is the organizational mistake you learned the most from?
