A Project Management Process Area at Maturity Level 2

The purpose of Requirements Management (REQM) is to manage requirements of the project’s products and product components and to ensure alignment between those requirements and the project’s plans and work products.

Requirements management processes manage all requirements received or generated by the project, including both technical and nontechnical requirements as well as requirements levied on the project by the organization.

In particular, if the Acquisition Requirements Development process area is implemented, the resulting processes will generate customer and contractual requirements to be managed by requirements management processes. When the Requirements Management and the Acquisition Requirements Development process areas are both implemented, their associated processes can be closely tied and performed concurrently.

Throughout the process areas, where the terms “product” and “product component” are used, their intended meanings also encompass services, service systems, and their components.

The project takes appropriate steps to ensure that the set of approved requirements is managed to support the planning and execution needs of the project. When a project receives requirements from an approved requirements provider, these requirements are reviewed with the requirements provider to resolve issues and prevent misunderstanding before requirements are incorporated into project plans. Once the requirements provider and the requirements receiver reach an agreement, commitment to the requirements is obtained from project participants. The project manages changes to requirements as they evolve and identifies inconsistencies that occur among plans, work products, and requirements.

Part of managing requirements is documenting requirements changes and their rationale and maintaining bidirectional traceability between source requirements, all product and product component requirements, and other specified work products. (See the definition of “bidirectional traceability” in the glossary.)

All projects have requirements. In the case of maintenance activities, changes are based on changes to the existing requirements, design, or implementation. The requirements changes, if any, might be documented in change requests from the customer or end users, or they might take the form of new requirements received from the requirements development process. Regardless of their source or form, the maintenance activities that are driven by changes to requirements are managed accordingly.

Refer to the Acquisition Requirements Development process area for more information about developing and analyzing customer and contractual requirements.

Refer to the Configuration Management process area for more information about establishing baselines and tracking and controlling changes.

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

Refer to the Project Planning process area for more information about establishing and maintaining plans that define project activities.

Refer to the Risk Management process area for more information about identifying and analyzing risks.
