Process Model
Specification Development
The specification development process describes the activities involved in developing a system specification, starting with the definition of the system boundaries to narrow down the scope of the specification. This is followed by the development of use cases as the basis for defining the life cycle model. The identification of all stakeholders that may interact with, be influenced by or influence the system. In the last step, the requirements are then collected and summarized in the system specification as a requirements baseline.
