Problem in performance calculations in PMGM

Hi there.

1. We have been implementing PMGM module of SuccessFactors. We are using 2 scales for Goals (percentage from 33 min to 110 max) and Competencies (scale 1 to 5). In calculating overall rating, we give 70 percent weightage to Goals and 30 percent weightage to Competencies. In order to make both scales same, we convert percentage achievement in goals to scale 1 to 5, based on a conversion criteria defined in an excel sheet.

The problem we are encountering is that when average achievement of goals by an employee is between 95 and 110, everything seems fine. But other than this range, things get messy. The conversion is not done correctly. Can someone please guide what to do?

2. There is an alternate approach we are working on. We are trying to eliminate percentage scale of goals scoring. We directly tried giving scores to goals achievement based on 1 to 5 scale. And developed custom fields to only record percentage completion of goals to alleviate client's reservations. That worked, but the problem here arose that we cannot show/display a custom field in summary section of performance form. If someone can guide on any possibility of showing custom field in summary section of performance form?

Can someone help in any one of the above mentioned approaches?

Hi there,

1. " we convert percentage achievement in goals to scale 1 to 5, based on a conversion criteria defined in an excel sheet. The problem we are encountering is that when average achievement of goals by an employee is between 95 and 110, everything seems fine. But other than this range, things get messy. The conversion is not done correctly. "
>>Do you mean when normalizing from one scale to another scale based on your custom conversion formula, it  does not work as expected? Are you using custom calculation rules defined in goal plan xml or are you manually inputting the goal rating after completing percentage achievement in excel?

As a reference on normalizing scores from one scale to another, here is an example of how sfsf normalizes scores :Overall performance rating scale is 1 -3; Competency section rating scale is 1 - 5 and the competency section rating is 4. Then the competency rating will be calculated in overall rating following the below formula: (((rating - original min)/(original max - original min)) * (new max - new min)) + new min ((4-1)/(5-1))*(3-1)) + 1 = 2.5

2. For the alternate approach you described, unfortunately summary section does not support configuring custom fields. You might consider configuring a custom section either above or below the summary section. Within this custom section, you could create a custom field to capture the desired data.

Thanks.
