The purpose of requirement management is to establish a
common understanding of the technical and non-technical requirements that will
be addressed by the project or organization between the customer and project or
organization, within the project or organization, and throughout the lifecycle.
The goals of requirements management are to ensure that requirements are
controlled to establish a baseline for development, acquisition, or management;
and to ensure plans, work products, and activities are consistent with the
requirements.
The RM plan establishes an orderly method by which the goals
of requirements management will be achieved.
The plan also communicates essential information to project participants
and helps newcomers get up to speed.
Consequently, the plan is a living document, which needs to be updated
and supplemented throughout its life.
