E16 · Include never-starters
Decision: Whose absence is hidden by active-user charts?
Readout: Retain zero-task mature users and avoid assigning a cause from absence.
Actual query output (synthetic), first rows:
| persona | eligible_users | zero_task_users |
|---|---|---|
| developer | 79 | 12 |
| marketing | 74 | 19 |
| training | 71 | 16 |
Model spoken answer: I would include never-starters in the denominator and ask what job they expected to do.
Caveat/counterargument: Could an invitation be intended only for review? No task does not identify the cause; no session instrumentation in this lab.
Next evidence: Role/intent and consented nonstarter research; session events if necessary.
Deliberately left out: Assumed churn reasons and demographic profiling.
