Capture User Activities
In this step, you identify the key user activities for the application under test. Because it is impractical and virtually impossible to simulate every possible user task or activity in a performance test, you need to decide which activities are most important to simulate. However, before you can do this, you must determine what the possible user activities are.
One place to start is to evaluate the competition’s Web site (or application, since competing applications may not be Web-based). Whether or not it is explicitly stated, at some point during the project it is likely to become very obvious that the goal is to allow your users to perform all of the activities available from the competitor. Knowing what these activities are in advance will prevent you from being surprised when they show up in the application — whether or not they appear in any of the documentation.
