How does PPM calculate a measure's goal accomplishment?
PPM can calculate the goal accomplishment for each measure according to your settings. Goal accomplishment standardizes measures to a comparable percentage value based on the planned values specified.
PPM calculates the goal accomplishment based on the measure evaluation, planned values 1 and 2, and the Min/Max planned value. A value of 100% represents complete goal accomplishment and 0% represents non-achievement of the Min/Max planned value.
The Min/Max planned value indicates the limit for 0% goal accomplishment and planned value 1 indicates 100% goal accomplishment. The span between planned value 1 and the Min/Max planned value represents the entire goal accomplishment span.
Calculation of goal accomplishment with positive measure assessment(greater values are assessed as positive):
Calculation of goal accomplishment with negative measure assessment(greater values are assessed as negative):
Goal accomplishment for process cycle time
For measures with negative assessment (that is, longer cycle times are assessed as negative), the calculation is as follows:
Degree of goal accomplishment = (max. planned value – actual value) / (max. planned value – planned value 1)
The span between planned value 1 and max. planned value (maximum value) represents the 100% span.
Actual value = 26.6h
Planned value 1 = 25.0h (100% goal accomplishment)
Planned value 2 = 26.0h
Max. planned value = 30.0h (0% goal accomplishment)
Degree of goal accomplishment = 68%
Goal accomplishment is independent of the evaluation of a measure, that is, whether a higher value means a better performance or not. A higher degree of goal accomplishment is always better.
