 The researchers will use waterfall model in the development of the Management System for Aijem’s Water Refilling Station. The selected methodology incorporates systematic development techniques to the project. Waterfall model is discipline approach; it requires each stage of the software development to be documented. Besides that, the correctness of the product is checked on each stage of the product building. This ensures only the correct product that fulfils the users requirements are built during the whole development process.
