Requirements Management is essential for the successful completion of projects as requirements are the single thread that goes through a project from conception through build, test and flight. Requirements are envisioned for each system to meet its needs, then refined, expanded and flown down to lower levels through an iterative process. Requirements Management ensures the accurate determination of all these requirements (from higher to lower level), their documentation and traceability, as well as close monitoring of changes over a project’s life cycle. Furthermore, it certifies through the process of requirements verification that the final product is in line with the original customer needs and expectations.
The Requirements Management is performed using Rational DOORS v9.6 (Dynamic Object Oriented Requirements System), which is a requirement management tool, with an open architecture that supports third-party plugins.
