Requirements are managed and inconsistencies with project plans and work products are identified.

The project maintains a current and approved set of requirements over the life of the project by doing the following:

·         Managing all changes to requirements

·         Maintaining relationships among requirements, project plans, and work products

·         Ensuring alignment among requirements, project plans, and work products

·         Taking corrective action

Refer to the Project Monitoring and Control process area for more information about managing corrective action to closure.

Requirements management typically includes directly managing changes to customer and contractual requirements developed by the acquirer and overseeing the supplier’s requirements management process. Requirements changes can result in changes to the supplier agreement.
