What is a system development life cycle and what are the phases in the cycle?
An information system includes data, people, procedures, hardware, and software. Teams of individuals are required to develop systems and an organized process (or set of steps) needs to be followed to ensure that development proceeds in an orderly fashion. This set of steps is usually referred to as the system development life cycle (SDLC). There are six steps in the SDLC. First, a problem or opportunity is identified. Next, the problem is analyzed and a program specification document is created to outline the project objectives. Next, a detailed plan for programmers to follow is designed using flowcharts and data-flow diagrams, from which the development and documentation of the program occurs. The program is then tested to ensure it works properly and installed so that it can be used. Maintenance and evaluation continues to ensure a working product is maintained. • What is the life cycle of a program?
