=**Systems Development Life Cycle**=

From the Curriculum Statement: The study of Stage 2 Information Technology Studies involves the development of computer-based systems to solve problems. A systems development life cycle is a problem-solving approach that students can use when creating computer-based solutions. The stages are rarely linear, and many students will find it useful to view system development as more than a simple step-by-step process. The systems development life cycle consists of the following stages: problem definition, analysis, design, development and validation, and evaluation. · The //problem definition// explains the problem and outlines the intended outcomes of the system. · //Analysis// is the identification of the data that needs to be stored and the data processing required. · //Design// is a process of developing a plan for the information system, using appropriate tools and concepts. · //Development// //and// //validation// involve building, testing, and checking the trial system. · //Evaluation// is the appraisal of the performance of the system against the problem specification. Students can choose their own individual problem and the outcomes that their proposed solution is intended to achieve. Depending on the type of system developed, there will be a differing emphasis on each stage of the systems development life cycle.
