Overview
Although system evaluation is an ongoing process throughout the performance testing effort, it offers greater value when conducted early in the test project. The intent of system evaluation is to collect information about the project as a whole, the functions of the system, the expected user activities, the system architecture, and any other details that are helpful in guiding performance testing to achieve the specific needs of the project. This information provides a foundation for collecting the performance goals and requirements, characterizing the workload, creating performance-testing strategies and plans, and assessing project and system risks.
A thorough understanding of the system under test is critical to a successful performance-testing effort. The measurements gathered during later stages are only as accurate as the models that are developed and validated in this stage. The evaluation provides a foundation for determining acceptable performance; specifying performance requirements of the software, system, or component(s); and identifying any risks to the effort before testing even begins.
