Rapid application development (RAD), is a software development process developed initially by James Martin in the 1980s. The methodology involves iterative development, the construction of prototypes, and the use of Computer-aided software engineering (CASE) tools. Traditionally the rapid application development approach involves compromises in usability, features, and/or execution speed. It is described as a process through which the development cycle of an application is expedited. Rapid Application Development thus enables quality products to be developed faster, saving valuable resources. This does not cite any references or sources. ...

History

Application development refers to the developing of programming applications and differs from programming itself in that it has a higher level of responsibility, including for requirement capturing and testing.^[1] Rapid Application Development was a response to non-agile processes developed in the 1970s, such as the Waterfall model. The problem with previous methodologies was that applications took so long to build that requirements had changed before the system was complete, often resulting in unusable systems. Starting with the ideas of Brian Gallagher, Barry Boehm and Scott Shultz, James Martin developed the Rapid Application Development approach during the 1980s at IBM and finally formalised it by publishing a book in 1991. Computer programming (often simply programming) is the craft of implementing one or more interrelated abstract algorithms using a particular programming language to produce a concrete computer program. ... The waterfall model is a sequential software development model (a process for the creation of software) in which development is seen as flowing steadily downwards (like a waterfall) through the phases of requirements analysis, design, implementation, testing (validation), integration, and maintenance. ...

Pros and Cons of RAD

Pros

1. Increased speed of development through methods including rapid prototyping, virtualization of system related routines, the use of CASE tools, and other techniques.
2. Decreased end-user functionality (arising from narrower design focus), hence reduced complexity
3. Larger emphasis on simplicity and usability of GUI design

Cons A rapid prototyping machine using Selective laser sintering. ... Categories: Stub | Software engineering | Data management ...

1. Reduced Scalability, and reduced features when a RAD developed application starts as a prototype and evolves into a finished application
2. Reduced features occur due to time boxing when features are pushed to later versions in order to finish a release in a short amount of time ^{[citation needed]}

Time boxing is a DSDM technique to plan out a project, for example the creation of a new IT system, by splitting the project up in a number of separate time periods (normally two to six weeks long). ...
