Describe instrumentation you can procure or prepare now or in an early sprint to ensure timely measurement and performance evaluation of the features that are developed in each sprint.
Performance Verification
You are the lead performance engineer in a team that is currently planning the sprints of a large software development effort. You must negotiate time for the preparation of measurement instrumentation and load generators to verify that the performance of the system is sound. At this point the performance and functional requirements are likely to be unstable or unspecified:
1. Describe instrumentation you can procure or prepare now or in an early sprint to ensure timely measurement and performance evaluation of the features that are developed in each sprint.
2. Explain how you might work with functional testers to develop load-driving scripts and scripts to verify that the system has functioned correctly after each performance test.
3. Explain why such verification is necessary, even if the system passes all functional tests before performance testing commences.
