Rewriting Requirements for Design

Maintaining consistency between requirements and the design developed to satisfy them is both important and difficult. Maintaining consistency is important to satisfying stakeholders desires, which the requirements express. Much of the difficulty of maintaining consistency stems from having redundant descriptions of requirements decisions one in the requirements document and a second in the design document typically recorded in widely divergent languages. To ameliorate this problem, we write requirements and design in such a way that requirements decisions and their expression in the requirements document are incorporated directly into the design document, which organizes the decisions and includes additional design decisions.
