Software Development Process
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 describe the problem to be investigated and the goal to be achieved. In addition, the introduction provides an analysis of the relevance of the research and discusses the paper’s five-chapter format. Problem Statement and Goal Traditional SDLC methodologies sometimes fall short in the new e-business software environment (Yourdon, 2000). They are often to “heavy” to keep up with the pace of e-business software development projects. In response to this problem, so called “light” SDLC methodologies have recently been developed and put to use. They are considered light because of the reduced documentation and managerial effort required. The goal of this paper is identify the strengths and weaknesses of these new lightweight methodologies and to make recommendations for their effective use. Relevance This research paper is relevant to the topic of SDLC. The paper begins with an overview of traditional SDLC processes. This is followed by an in-depth look at new lightweight methodologies and an analysis of their appropriateness to different types of software development efforts. Format This research paper is a descriptive study formatted in five chapters. The first chapter covers the paper’s problem statement and goal, relevance, and format. This is followed in the second chapter by a review of the literature relevant to the problem. In the third chapter, the research methods and online tools and resources employed during the
