Comparable Ratings
Change is calculated only when target identity and rating type match across the selected time points.
Important Limits
The product must not calculate change across different clients, nonmatching targets, or different rating types, and must not infer causality or apply unsupported thresholds.
Does COPM Change Score collect new ratings?
No. It uses previously captured COPM ratings and calculates change from comparable time points.
What makes a comparison valid?
A comparison is valid when the same target identity and same rating type have baseline and follow-up ratings.
Can it compare performance and satisfaction together?
No. Change is rating-type-specific, so performance and satisfaction are compared separately.
What is saved?
The COPM Change Score tool itself and reusable comparison setup are saved; fictional sample ratings and change results are not saved as real client data.
