There are numerous ways of working out the potential, and actual, financial benefits of implementing test process improvements. Here we show one way, based on the method Experimentus uses and for a TMMi driven initiative.

Test process improvement benefits can be broken down into direct and indirect types. Sometimes the indirect benefits are larger, or more important, than the direct ones, so they should not be ignored. It is well worth taking into account the indirect benefits when the overall value of an improvement program is being calculated.
