How do I estimate the users directly exposed by each staged rollout and cap?
Segments must be disjoint if you use the total. Round down fractional users and apply the absolute cap.
Open Change Exposure MapTry the worked example
These are the example inputs from Change Exposure Map. Replace them in the tool to run your own case.
| Segment | Eligible users | Rollout % | Exposure cap |
|---|---|---|---|
| East | 1200 | 15 | 150 |
| West | 900 | 10 | 60 |
Example result
210 planned exposures

Where the idea came from
Estimate the users directly exposed by each staged rollout and cap. The demonstrated change reaches a pull request and a human approval point before merge. Benchcraft designed this tool’s inputs, decision rule and example for this office task.
