Activation rate by cohort: what the aggregate number hides

Table 6Activation rate by cohort: what the aggregate number hides

Cohort view	Keep fixed	Question to ask
Entry period	Cohort-entry definition and calendar boundary	Did the eligible population change?
Event version	First-value event and required properties	Did instrumentation change what counts?
Maturity	Full observation window and as-of date	Are later cohorts still incomplete?
Operating context	Plan, channel, segment, region, and onboarding stage	Did composition or process change?
Later validation	Retention or renewal rule and horizon	Is the later outcome being kept separate?
