Develop an understanding with requirements providers on the meaning of requirements.

To avoid requirements creep, criteria are established to designate appropriate channels or official sources from which to receive requirements. Those receiving requirements conduct analyses of them with the provider to ensure that a compatible, shared understanding is reached on the meaning of requirements. The result of these analyses and dialog is an agreed-to set of requirements.

Typical Work Products

Subpractices

1.    Establish criteria for distinguishing appropriate requirements providers.

2.    Establish objective criteria for the evaluation and acceptance of requirements.

Lack of evaluation and acceptance criteria often results in inadequate verification, costly rework, or customer rejection.

3.    Analyze requirements to ensure that established criteria are met.

4.    Reach an understanding of requirements with requirements providers so that project participants can commit to them.
