Reflect on a failed decision and redo it

Describe a high-stakes decision you made that turned out wrong. (a) Provide context: objective, options considered, constraints, stakeholders, and the data available at the time. (b) Reconstruct your decision framework (trade-offs, risks, expected value) and why it failed; identify unknown unknowns and cognitive biases. (c) Explain the signals that revealed the mistake, how you course-corrected, how you communicated across teams, and the measurable outcomes. (d) If you could redo it, what specific process changes, safeguards, or alignment mechanisms would you implement to prevent recurrence? What mechanisms have you instituted since?
