System analysis is the process of gathering and interpreting data, identifying issues, and breaking down a system into its constituent parts. The process of planning a new business system or changing an old system by describing its components or modules to meet specified needs is known as system design. There are six phases of the system life cycle that we need to know for performing system analysis and design which are Preliminary Investigation, Systems analysis, systems design, Systems Development, Systems Implementation, and System Maintainance. If the system is not feasible, six phases of the system life cycle may be used.
