CHAPTER 3: METHODOLOGY 3.1 Introduction Methodology is a model created to help project developers to plan and schedule their project so that it is more organized and systematic task. It is a method used to breakdown a large project into smaller and more manageable tasks. With methodology as a guideline‚ each stages of project development will be treated with its needs. It is important for project developers to keep track on the progress of their project. Project developers use Methodology
