P and R Measures are the statistics used to evaluate the efficiency and effectiveness of business processes.

The 'P' measures are the Process measures - these statistics that record the number of times things occur. Examples would include:

  • the number of times an error loop is used
  • the number of times an approval loop is used
  • the average time to complete a particular task in the process
and show how efficient the process is.

The 'R' measures are the Results measures - these statistics record the 'outcomes' of the process. Examples would include:

  • the number of occasions when the process completed correctly
  • the number of times rejections occurred
  • the number of times approval was not given
and show how effective the process is.
