The purpose of this exercise is to estimate what the practical performance of the process can be or will be based on the process design, process implementation and KPI definition. This activity is basically an extension to the similar activity performed for the Implementation Independent Process Design but now also taking the implementation aspects into account.

If possible the KPIs of the current processes are also calculated or measured to establish a baseline for the KPIs. This will establish a baseline that can demonstrate if the envisaged changes have brought the expected benefits.
