Improving the Rapid Application Development process model

Software process model is a framework to develop the software for any application. Process model gives the overall strategy for the application development. Depending the nature, available resources and the scope of the project we have to select the process model. Rapid Application Development model is an incremental development model. It suits for the projects whose requirements are well understood, can deliver the software in increments within the short period and scalable. It adapts high speed waterfall model. It employs more than one RAD teams and uses automatic code generation tools for modeling and construction of the application. For large, scalable projects if a system cannot be accurately elasticized constructing the required components for RAD will be challenging and requires more efforts and time for creating stubs and drivers in unit testing. This paper gives steps to improve the effectiveness of the modules and reduce the risks in testing at component level.
