Symptom
Upon activating a Calibration session, the performance ratings from previous year appear to be lower than what can be seen in the Employee Profile.
Source of the ratings in the Calibration session: Employee Profile
Source of the ratings in the Employee Profile: performance forms from the previous year
Environment
SAP SuccessFactors HCM Core
Reproducing the Issue
- Create a Calibration template with the setting to pull Performance Ratings from Employee Profile.
- Launch a Calibration session from the template.
- Observe that every employee's rating is lowered in the session compared to the ratings that are visible in the users' Employee Profiles.
Cause
Different rating scales are set in the performance forms (1-4) and in the calibration session (1-3), and the ratings got normalized by the system.
Resolution
From the original 4 point scale, the system stores the normalized rating, equally distributing the rating scale from 0% to 100%:
|
Original rating |
Normalized (%) rating |
|
1 |
0 |
|
2 |
0.33 |
|
3 |
0.66 |
|
4 |
1 |
Taking any normalized rating and showing it on a 3 point scale would use this conversion, dividing the range into 3 equal partitions:
|
Normalized rating range |
Output rating |
|
0.0 - .3333 |
1 |
|
.3334 - .6666 |
2 |
|
.6667 - 1.0 |
3 |
So, the original scores from the form translate into the 3 point scale like so:
|
Original rating |
Normalized (%) rating |
Output rating |
|
1 |
0 |
1 |
|
2 |
0.3333 |
1 |
|
3 |
0.6666 |
2 |
|
4 |
1 |
3 |
We always recommend not to use multiple scales, instead use 1 standard scale throughout the processes whenever possible.
