The Rapid Application Development (RAD) approach to software development puts clear emphasis on development and prototyping‚ and less on planning tasks. In RAD‚ prototyping acts as an alternative to design specifications. RAD works well when user interface is given a bigger focus rather than non-graphical user interface programs. RAD refers to a development life cycle designed to make development much faster and produce higher quality systems than traditional life cycle. The key objectives of RAD

Since it is a critical process to provide high efficiency‚ it was inavitable to integrate this quick cycles approach with testing. A process called “Test-Driven Development” was born in 2003 to provide exactly that. In TDD‚ before each cycle‚ requirements are examined and are evolved into the test cases. After that step‚ the software is developled only to pass these specific test and added to the product. By this method it is easier to prevent any piece

Michael Wilson‚ David Duce Informatics Dept.‚ Rutherford Appleton Laboratory Dan Simpson Dept. of Computer Science‚ Brighton Polytechnic. ABSTRACT Developments in software engineering have led to models of the system life cycle incorporating the use of prototyping and formal methods of program verification. These are becoming supported by integrated project support environments and permit the planning and monitoring

Chapter 1 Introduction System Development Life Cycle (SDLC) methodologies are mechanisms to assure that software systems meet established requirements (DOJ‚ 2000). These methodologies impose various degrees of discipline to the software development process with the goal of making the process more efficient and predictable. For the purpose of discussion in this paper‚ SDLC methodologies are divided into two groups (traditional and lightweight). The following introductory sections

A wide variety of such frameworks have evolved over the years‚ each with its own recognized strengths and weaknesses. One system development methodology is not necessarily suitable for use by all projects. Each of the available methodologies
