This is basically four questions stapled together and they want you to move through all of them without losing the thread.
Start by acknowledging the tradeoff and framing it as a question of net long-term user value, not just short-term metric lifts. Then propose a structured plan: estimate long-term impact via proxies and modeling, design mitigations to reduce harm, and recommend a phased rollout with guardrails. Finally, outline a post-launch monitoring plan that tracks both notified and non-notified cohorts, with clear success and rollback criteria.
Pro tip: Anchor the discussion in Meta's core value of long-term user value and ecosystem health; explicitly connect the tradeoff to potential churn and engagement decay, showing you think beyond the experiment window.
Communicate that the experiment shows a classic short-term gain vs. long-term risk tradeoff. Emphasize that the drop in non-notified account usage could signal notification fatigue or cannibalization, which may erode overall engagement and retention.
Use proxies like session frequency, time spent, and actions per user to model long-term value. Leverage holdout groups, cohort analysis, and predictive churn models to quantify the risk of losing multi-account users.
Suggest targeted mitigations such as frequency capping, personalized notification timing, or segment-specific treatment. Consider A/B testing these mitigations to find a balance that preserves lifts without harming non-notified accounts.
Recommend a phased rollout starting with a small percentage of users, with predefined guardrail metrics (e.g., non-notified account usage, churn rate). Include clear criteria for pausing or expanding based on monitoring results.
Outline a monitoring plan that tracks both notified and non-notified cohorts over time, with dashboards for key metrics, alerts for anomalies, and periodic reviews. Include a plan for long-term holdout to measure cumulative impact.
