## Practical steps

1. Choose one transition
Measure a specific step, such as completed logins divided by observed welcome views. Do not silently substitute all venue visitors for a count you do not have.

2. Align the window
Use matching time zones and date ranges. Decide how a journey that begins before the window and completes inside it will be handled.

3. Show the counts
Publish the numerator and denominator with the rate in internal reports. Note missing events, test records and changes in how the system measures them.

## Review before acting

Recalculate the example from the raw counts. A colleague should be able to reproduce the percentage without guessing at the definition.

Watch for: Do not compare a completion rate from one denominator with an opt-in rate from another as if they measure the same behavior.
