Computer Based Systems
The system development cycle is a method used to create a system where none has existed before and/or modify an existing system. It is sometimes simply called System Development. It involves a number of stages representing a standard strategy for taking a problem from start to finish. 1. Conservative-working systematically through the steps. 2. Radical-Cycling through the cycle several times until the final result is achieved. The above diagram shows that the system development cycle is represented by 5 broad stages: Requirements analysis or.………Feasibility study. -Duration is relatively short compared to the rest of the development cycle. -It is important to get it right the first time else mistakes could be costly. In the worst case a large oversight would require starting over from step one. The aim of this stage is to see how the present system functions and to identify the nature of the problem (problem definition). once the problem has been identified a report is compiled
