Respond to long-term concerns after A/B success

Your model performs well in an A/B test (statistically significant lift on the primary metric). However, your manager believes the model may harm long-term user experience (even if short-term metrics look good).

How do you respond and what actions do you take?

Include:

• How you communicate with the manager and stakeholders
• What data/metrics you would propose to evaluate long-term impact
• What you would do if you cannot conclusively prove safety quickly
