The activation-rate cohort worksheet

Keep the eligible cohort, first-value event, fixed window, activation count, and later outcome visible as separate objects.

An eight-row worksheet with five columns for cohort and eligibility, observed action and value event, window and timing, activation count, and later validation status.COHORT ANDELIGIBILITYUnit grain, entry event,and eligibility rule.OBSERVED ACTION ANDVALUE EVENTRecord setup, the declaredfirst-value event, or none;only the declared valueevent counts.WINDOW AND TIMINGEvent timestamp andfixed observationwindow.ACTIVATION COUNTOne-time yes or nocontribution to thenumerator.LATER VALIDATIONSeparate day-60 status orlater outcome.Eight rows are deliberate: each synthetic account is counted once. The activation rate uses the declared cohort and window; laterstatus is not part of the numerator.

  • B Activation rate is the share of eligible units that reach a declared first-value event inside a fixed window Author framework · G03-OWN-C1
  • B A reproducible activation record names unit grain, entry event, eligibility, activation event, timing, window, and counting rule Author framework · G03-OWN-C3
  • B The synthetic worksheet has eight eligible units, four first-value events inside 14 days, and 4 / 8 = 50% Author synthetic arithmetic · G03-OWN-C4
  • B Setup completion and descriptive retention among activated units are separate from activation rate Author framework · G03-OWN-C5
  • B Changing event, cohort, unit grain, or window changes the comparison object before it proves product improvement Author boundary · G03-OWN-C6
