Evaluation Of A Sdlc, System Development Life Cycle

1. According to Rosenblatt (2014), a SDLC, system development life cycle, describes how to plan and manage systems development and the activities and functions of systems developers will perform. The waterfall model is divided in five steps and the result of each one is a deliverable to the next step. The first step is called Systems Planning and starts when the IT department does a systems request. This phase is responsible for doing a preliminary investigation to know the situation and evaluate the necessity of this new system. The principal part of this investigation is called feasibility study and it is responsible for showing anticipated reviews of the costs, benefits and course of action. The second step is called Systems Analysis and it purpose is to build a document with the system requirements, showing details as management and user requirements, benefits, development strategies and costs. The third step is the System Design, happens when is necessary to create a physical model and identify the processes (inputs and outputs), satisfying the requirements. Its deliverable is the systems design specification. The fourth step is the System Implementation and during this phase, the new system is constructed. The purpose of this step is to deliver an information system, functio ning and documented. The last step is the Systems Support and Security and during this phase, the IT department is responsible for maintaining, enhancing and protecting the new system.
