The document discusses integrating performance testing into agile development lifecycles. It notes that performance testing and agile development both involve repeating cycles of planning, testing, and improving. However, bringing the two together can be complicated due to unknowns and variable notions of acceptance. The document provides keys to success, including involving management and developers, making performance part of user story acceptance, and involving performance testers throughout the development cycle.
