Material deleted from Module 2:
Rational promotes an iterative approach to requirements management. This means that the process workflows are repeated during each lifecycle phase (inception, elaboration, construction, and transition) and that progress is incremental. This process makes it possible to slowly build functionality and to identify possible obstacles to success and to address them at an early stage.
Six-Step Approach to Requirements Management
A solid understanding of requirements management is critical to your success; no software tool can compensate for an inadequate or sloppy process. The following six steps appear to be an integral part of successful requirements management:
Analyze the problem (Module 4)
Understand stakeholder needs (Module 4)
Define the system (Module 4)
Manage the scope of the project (Module 5)
Refine the system defintion (Module 6)
Steps 1 and 2 are explained briefly in Module 4; more information about them is available from Requirements Management with Use Cases, a class offered by Rational University. Steps 3-6 are supported by several features offered by RequisitePro.
