How the Ranking Score Is Calculated
The ranking score is a calculated value from 0 to 100 for each worker who has at least one ranking. It considers the rankings of all managers who ranked the worker, who is in the viewing manager's organization.
Conditions That Affect the Ranking Score
The following conditions affect the ranking score:
- The ranking given by each manager. The rankings of higher-level managers have more weight because the ranking compares the worker against a larger population of workers.
- The viewer's position in the hierarchy
- The number of other workers ranked
How the Ranking Score Is Calculated
This formula derives the ranking score:
100 x [SUM(Group Population - Ranking + 1)] / SUM(Group Population)The following table describes the variables in the equation:
| Equation Variable | Description |
|---|---|
| Group Population |
Includes all ranked workers reporting directly or indirectly to the manager viewing the score. The group population must include at least 10 workers for <name of application or process> to calculate a score. |
| Ranking | The position value given to a worker; it must be a positive, whole number from 1 to N. |
| 1 | Added to the numerator to ensure that workers ranked 1 by all managers receive a score of 100. |
| (Group Population - Ranking + 1) | Summed for the manager looking at the score and all lower managers who ranked the worker. |
The scores are whole numbers only.
Example 1
John views the rankings for a worker who reports directly to Peter. John ranked the worker 299 out of 2200 and Peter ranked the worker 1 out of his 7 workers ranked.
| Manager | Worker's Ranking | Workers Ranked | Group Population - Ranking + 1 |
|---|---|---|---|
| John | 299 | 2200 | 1902 |
| Susan | 75 | 600 | 526 |
| Henry | 15 | 90 | 76 |
| Nancy | 4 | 26 | 23 |
| Peter | 1 | 7 | 7 |
| Sum | NA | 2923 | 2534 |
The ranking score of the worker John views is 86.
Calculation: (100 * 2534) / 2923.
Example 2
Nancy views the same worker as John, in example 1.
| Manager | Worker's Ranking | Workers Ranked | Group Population - Ranking + 1 |
|---|---|---|---|
| Nancy | 4 | 26 | 23 |
| Peter | 1 | 7 | 7 |
| Sum | not applicable | 33 | 30 |
The ranking score of the worker Nancy views changes to 91.
Calculation: (100*30) / 33.
Example 3
Nancy views the same worker, with the same ranking as in the previous examples. However, she views a smaller number of workers ranked in her organization.
| Manager | Worker's Ranking | Workers Ranked | Group Population - Ranking + 1 |
|---|---|---|---|
| Nancy | 4 | 10 | 7 |
| Peter | 1 | 7 | 7 |
| Sum | NA | 17 | 14 |
The ranking score of that worker Nancy views is now 82.
Calculation: (100*14) / 17.
