Performance Analysis Phase

With all functionality clear and understood by the development team, the next stage is to consider the performance required. Performance indicators include:

Speed of response.


Strange effects avoidance.

Preparation for the design stage.

Speed of response to the requirements is the usual way an end user will judge the operational system. When an end user makes an inquiry, he or she expects the whole answer to that inquiry. Some projects allow the response to be a simple message such as "inquiry being dealt with please wait." The actual processing has taken an unacceptable amount of time, which frustrates the end user and gives the project a poor name. If a requirement states that "the response to an inquiry must appear within x seconds," the performance analysis stage should be sure that it is physically reasonable and technically possible. Stakeholders sometimes make excessive demands. These must be sorted out and agreement reached in this phase.

Routing users through the final system will also be judged as good or poor performance. An end product of the previous stage was a logical grouping of the requirements. Now is the time to start thinking about final performance routing options. Other aspects on which the final system will be judged are how it performs when presented with unexpected input, how it allows the end users to cope with unexpected output, and the error messages and options presented to the end users when strange events occur. This is referred to as strange effects avoidance. Now is the time to decide how some of the requirements are to be handled.
