Describe a time when you had to resolve a disagreement between the marketing and product teams over the definition of a key conversion event used in your growth funnel. How did you handle it and what was the outcome?

STAR + step‑by‑step strategy (120‑150 words, no story):

1. Identify stakeholders and clarify objectives.
2. Map current event definitions and data lineage.
3. Propose a unified metric with measurable thresholds.
4. Validate with a quick cohort test.
5. Document changes and communicate to all teams.
6. Monitor impact and iterate.

I once mediated a conflict between marketing and product over the definition of a conversion event in our funnel. Marketing wanted to use the first purchase timestamp, whereas product insisted on subscription activation. I first gathered both teams to map the event flow and identify data gaps. I proposed a composite metric that counted either event within a 48‑hour window, ensuring that users who purchased before activating were still captured. We ran a cohort test on a 10% sample, which showed a 12% lift in conversion rate and no data integrity issues. I documented the new definition in our data glossary, updated dashboards, and scheduled a quarterly review. The resolution not only improved funnel accuracy but also strengthened cross‑functional collaboration and set a precedent for future metric disputes.
