2 quotes

Concerns Raised

Relying on misleading aggregate metrics like DAUs instead of individual user behavior.
Misusing dot plots by tracking low-value 'vanity' events like 'app open' instead of core value actions.
Using too wide a time period (e.g., weeks) for dot plots, which obscures meaningful daily patterns.

Opportunities Identified

Gaining a rich, qualitative understanding of user engagement patterns that aggregate charts hide.
Identifying specific user segments and behaviors that correlate with high retention.
Proactively identifying at-risk B2B customers by visualizing low seat activation and usage.
Discovering which product features are causal to long-term user engagement.
