The four phases are systems planning and selection, systems analysis, systems design, and systems implementation and operation. Systems planning and selection is the first phase of the SDLC, in which an organization’s total information system needs are analyzed and arranged, and in which a potential information systems project is identified and an argument for continuing or not continuing with the project is presented. During systems analysis, the current system is studied and alternative replacement systems are proposed. During systems design, analysts convert the description of the proposed system into logical and then physical system specifications. During systems implementation and operation, the information system is coded, tested, and installed in the organization. During this phase the system is systematically repaired and improved.

Now, do we have need to complete all four of these phases when we reuse software? Why or why not?
