James Martin's Rapid Application Development

James Martin's Rapid-application development (RAD) is an iterative adaptive approach to rapid development. According to RAD,development adaptive process > planning. Prototypes are often used in addition to or sometimes even in place of design specifications.

RAD is especially well suited for companies good at Agile and that like components or pre-existing classes (API's).

Phases -

Requirements planning phase – Users, managers, and IT staff members discuss and agree on business needs, project scope, constraints, and system requirements.

User design phase – users interact with systems analysts and develop models and prototypes that represent all system processes, inputs, and outputs, typically with a combination of Joint Application Development (JAD) techniques and CASE tools to translate user needs into working models.

Construction phase program and application development, only users can still suggest changes.Unit-integration and system testing.

Cutover phase – data conversion, testing, changeover to the new system and user training are the staples of the last stage of james MArtin's RAD.


Modelling and construction may occur in parallel. The former typically lasts from 60-90 days, while the latter may make use of component reuse, automatic code generation and testing.
