Q)Explain in detail RAD software life cycle model [M-2012] (Rapid Application Development Model) Ans: Builds on the Incremental model with emphases on short development cycle. In other words high speed waterfall model Components are build using this model as a fully functional units in a relatively short time It assumes that the system can be modularized RAD will fail if you don’t have strong and skillful teams High performance might be an issue The Phases of RAD Model Business

1 Prototyping This lecture will examine the role of prototyping in Systems Development. It will describe what prototyping is‚ why it is used and how it may be applied in Systems Development Projects. It will establish approaches to evaluating a Prototype and finally it will discuss criteria for successful use of prototyping in a Systems Development Project. 1.1 What is a Prototype – and why would we need one? Prototype can be described as: “A working model of (parts of) an information system

information-gathering technique and design method proposed for this project is the Rapid Application Development method‚ acronym RAD. The RAD methodology is a process in which research of user requirements is compiled before producing any detailed system design documents. Using this approach decreases the time needed to design and implement new systems. Factors of Successful Analysis The Rapid Application Development method incorporates using three different approaches of systems analysis. These sub-approaches
