Determine Usage Model
During this activity, the performance tester graphically depicts the usage model to be used to performance test the system. This model will contain both user and system activities, how and often these activities occur by both time and relative percentage. A good target is to model the 20% of the user activity that accounts for 80% of the total volume of activities, all expected system activity, all performance critical activities and all areas identified as high risk for causing poor performance.
