Abstract
Software development life cycle (SDLC) is critical and remains the most significant part of software development in requirement engineering. There exists several SDLC each designed for specific needs to accommodate available resources and skills; they are compatible with certain programming languages and toolkits, and are of immense benefits to the software engineers. Despite its popularity and strengths over major weaknesses of other models, Iterative model is less acceptable by programmers and not widely in use in industry. This study examines the concepts of Iterative models and presents its real time examples to make the SDLC more understood to software developers. The practical application of the model is exemplified, motivation for its use are highlighted, and the requirement as well as requirement activities in each phase are tabulated. This will raise users’ awareness on the Agile Software Development Model and attract software developers to appreciate the Iterative Model and make a better use.
