A systems engineering view of requirements management for software-intensive systems

The importance of requirements management is widely understood and appreciated. Nevertheless, the rules used to guide the process, while recognized, but rarely followed in a consistent way. Requirements management often exists as a vague, undefined collection of process fragments. This presentation explores the system decomposition function of systems engineering. Transition Zones are defined that mark the boundaries where, during the decomposition process, the change of technical disciplines is needed. The success of the requirements management process here is defined as the Systems Engineer´s ability to recognize and manage these transitions.
