Performance Review Completion Factor is a measure of the extent to which employees receive regular performance and career development reviews.
Performance Review Completion Factor = (Rc / Ra) x 100
Rc = total number of performance reviews completed in a given time period.
Ra = total number of employees that should have received a performance review in that same time period.
This indicator is included in the book: Key Performance Indicators - the 75+ measures every manager needs to know, which contains an in-depth description of this KPI, as well as practical advice on data collection, calculations, target setting, and actual usage.
