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
