Question

Evaluate the Success of a New Group Video Feature

Context

You are assessing the launch of a Group Video feature on a social media platform. The feature allows multiple users to participate in the same video call. You need to determine whether the feature is successful.

Assume:

The platform already supports 1:1 video calls and messaging.
Group calls can be created and joined via invites.
There is risk of interference (network effects) because users call each other.

Task

Discuss the following:

Key metrics (primary, secondary, guardrails) to evaluate success.
An A/B experiment design that accounts for network effects and measurement.
Clear, quantitative success criteria (go/no-go) and how you’d interpret results.
Major trade-offs and risks (product, measurement, and operational) and how you’d mitigate them.
