Mission 3: Conflicting A/B Test Results
Explore a five-step framework that empowers you to interpret conflicting A/B test results confidently. Learn to define success metrics, segment data for insight, weigh short-term versus long-term impacts, and make clear data-driven decisions. This lesson prepares you to communicate your reasoning clearly during interviews and real-world product management scenarios.
We'll cover the following...
- Why conflicting A/B results matter
- Step-by-step framework
- Step 1: Clearly define your success criteria
- Step 2: Segment and dive deep
- Step 3: Assess long-term vs. short-term impacts
- Step 4: Investigate underlying reasons
- Step 5: Decide rollback, iterate, or accept
- Example: Applying the framework
- Evaluation criteria for a strong answer
This lesson equips you with a systematic framework to confidently interpret and act on conflicting A/B test results. By clearly understanding key metrics, trade-offs, and potential pitfalls, you’ll be prepared to make thoughtful, data-driven decisions and effectively communicate your reasoning during interviews.
Why conflicting A/B results matter
In real-world product management, A/B tests rarely yield perfectly straightforward results. Conflicting outcomes, where one metric improves while another worsens, often arise and pose challenging decisions.
Should we prioritize short-term gains or long-term health?
Which metric truly reflects user value?
What consequences come from overlooking negative signals?
