Question
Tell one story where you shipped a bounded first version, learned that an assumption was wrong, and corrected it quickly. State the boundary, signal, correction, and impact without hiding the original mistake. ## Preparation - Write the user or stakeholder, the constraint, and the decision in one sentence each. - Choose one measurement or observable fact that can support the answer. - Name one alternative and the reason it was not selected. ## Review checklist 1. Did I state the concrete constraint before describing the solution? 2. Did I separate my own decision and work from the team's work? 3. Did I name evidence or a measurement rather than relying on confidence? 4. Can I answer every follow-up without changing the original facts? ## Staged follow-ups 1. Explain why the first version was safe enough. 2. Name the earliest signal that contradicted the assumption. 3. Describe the correction you personally made. 4. Say what process changed afterward.
