Product or output of each stage of the life cycle that is the basis for such sign-offs. The project definition stage results in a proposal for the development of a new system. The systems study stage provides a detailed systems proposal report outlining alternative solutions and establishing the feasibility of proposed solutions. The design stage results in a report on the design specifications for the system solution that is selected. The programming stage results in actual software code for the system. The installation stage outputs the results of tests to assess the performance of the system. The post-implementation stage concludes with a post-implementation audit to measure the extent to which the new system has met its original objectives. We now describe the stages of the life cycle in detail.
