Definition of measures

The starting point for the calculation of measures and dimensions is the process tree. When calculating, for all the measures specified in the process tree configuration file (useki XML element), the definition in the measure configuration (kidef XML element) is retrieved and the associated calculation rule (calcattr XML element) is executed. This procedure only calculates measures that are used in the process tree, and optimizes the performance of the Measure calculator independently of the number of defined measures. Dimensions are calculated in the same way (usedim XML tag).

The graphic below illustrates the dependencies between the measure definition and the process tree definition:

The measure configurations supplied with the PPM system (*_keyindicator.xml files in the directories <PPM installation directory>\ppmmashzone\server\bin\agentLocalRepo\.unpacked\ppm-client-run-prod-<version>-runnable.zip\ppm\ctk\ctk\examples\custom\<client template>\xml contain definitions of the most common, generally applicable measures and dimensions. This default configuration can easily be expanded in the PPM Customizing Toolkit module Measures and dimensions to include project-specific measures.

Warning

Avoid using the suffixes _NUM and _SUM when assigning internal measure names. These suffixes are used internally by the Measure calculator.
