5.4.2.1 Decomposition
Decomposition is a technique used for dividing and subdividing the project scope and project deliverables into smaller, more manageable parts. The work package is the work defined at the lowest level of the WBS for which cost and duration can be estimated and managed. The level of decomposition is often guided by the degree of control needed to effectively manage the project. The level of detail for work packages will vary with the size and complexity of the project. Decomposition of the total project work into work packages generally involves the following activities:
Identifying and analyzing the deliverables and related work;

Structuring and organizing the WBS;

Decomposing the upper WBS levels into lower-level detailed components;

Developing and assigning identification codes to the WBS components; and

Verifying that the degree of decomposition of the deliverables is appropriate.

5.2.3.2 Requirements Traceability Matrix
The requirements traceability matrix is a grid that links product requirements from their origin to the deliverables that satisfy them. The implementation of a requirements traceability matrix helps ensure that each requirement adds business value by linking it to the business and project objectives. It provides a means to track requirements throughout the project life cycle, helping to ensure that requirements approved in the requirements documentation are delivered at the end of the project. Finally, it provides a structure for managing changes to the product scope.
Tracing includes, but is not limited to, tracing requirements for the following:
Business needs, opportunities, goals, and objectives;

Project objectives;

Project scope/WBS deliverables;

Product design;

Product development;

Test strategy and test scenarios; and

High-level requirements to more detailed requirements.

Attributes associated with each requirement can be recorded in the requirements traceability matrix. These attributes help to define key information about the requirement. Typical attributes used in the requirements traceability matrix may include: a unique identifier, a textual description of the requirement, the rationale for inclusion, owner, source, priority, version, current status (such as active, cancelled, deferred, added, approved, assigned, completed), and status date. Additional attributes to ensure that the requirement has met stakeholders' satisfaction may include stability, complexity, and acceptance criteria.
Process: 5.2 Collect Requirements
Definition: The process of determining, documenting, and managing stakeholder needs and requirements to meet project objectives.
Key Benefit: The key benefit of this process is that it provides the basis for defining and managing the project scope including product scope.
