Final answer:
PMs need to follow the program's T&E master plan to plan, resource, and document the T&E of IS and IT systems. Details of this master plan are based on organizational or governmental guidelines.
Step-by-step explanation:
Project Managers (PMs) must ensure that Testing and Evaluation (T&E) of assigned Information Systems (IS) and Information Technology (IT) systems are well planned, resourced, and documented. This should be done according to protocols outlined in the program's T&E master plan. The specifics of the reference in question were not provided, but typically this would adhere to guidelines provided by the organization or government entity responsible for the systems, such as the Department of Defense (DoD) for military applications. The T&E master plan lays out the strategy for testing and evaluation throughout the lifecycle of the system to ensure that all requirements are met and that the system functions correctly.
