Describe leading through stakeholder conflict and ambiguity

Describe a time you had to push back on a senior stakeholder to stop a rushed launch of a metric/report or experiment you believed was invalid. Include: exact dates, team size and roles, the decision at stake, what made the request risky (e.g., p-hacking, missing final review, non-latest data), the specific principles you used to influence without authority, the hard trade-offs you made, and the quantitative outcome. Then reflect on what you would change if you faced the same situation again and how you created long-term process fixes.
