Performance analysis and feedback might require simple code changes, readjustment of the communications structure between components, or even refactoring of the design. This implies that the performance experts might need to communicate with team members about all aspects of the project.

It is not necessary for the performance experts to be project experts as well.

The performance experts should be responsible for maintaining the project’s performance goals, and for identifying areas that need improvement. Performance experts should also be responsible for defining alterations to the project that will help to attain the performance goals.
