Each of the eight stages of the UCD Application Development Methodology has a specific objective or purpose. Each stage assumes a particular input(s) and in turn produces a specified output(s).
The ADM is structured so that each of the eight stages can be both funded and executed as an independent project. Each such project has a defined set of inputs, tasks and a set of intended outputs. The ADM structure is designed so that the stages will be executed in sequence. Under certain circumstances, one or more stages may be skipped. There are also conditions under which execution of a stage is interrupted in order to recycle through a preceding stage(s) to rework or update some aspect of that predecessor stage's deliverables.
Several of the stages provide that its output consist of deliverables whose scope is a meaningful subset of the scope of the stage's input. The scope of a stage's input and output is usually expressed in terms of business activities, business events, entity types, business locations and/or organization units.
Following is a descriptive overview of each of the eight stages including their major inputs and outputs:
Rapid Application Development (RAD)
- 10. Requirements Planning (for RAD)
