RAD Development

Paper Summary:

A discussion of the pros and cons of RAD development. RAD (Rapid Application Development) refers to an escalated project development life cycle in systems development. This is accomplished utilizing elements of traditional, structured development in concert with prototyping and joint application development (JAD) techniques.

From the Paper:

"RAD utilizes prototyping and user feedback as it's main mechanisms. It is applicable to situations where a user community will have significant input to the system, the requirements of the new system are undefined, or there is a high degree of possibility that the requirements and feature set will change as the project proceeds. (21st Century Technology, 2003). RAD is a flexible process, incorporating a combination of tools in different orders of priority and concentrations as a means to an end.
Structured systems development methodology was the first formal method established. Typically associated with large scale, centralized corporate projects involving mainframes, the structured systems methodology was categorized by a "top-down, functional decomposition" lifecycle otherwise known as "waterfall". This methodology was often employed using COBOL."
