CHAPTER 20 SYSTEMS DESIGN, IMPLEMENTATION AND OPERATION In chapter 18 we focused on the first phase of the Systems Development Life Cycle – Systems Analysis. Chapter 20 deals with the remaining four phases: - conceptual systems design - physical systems design - systems implementation and conversion - operation and maintenance CONCEPTUAL SYSTEMS DESIGN In the conceptual systems design phase, the developer creates a general framework for implementing user requirements

The system planning and selection stage addresses the needs or opportunities that can be achieved by an IT proposal. During this step, we must consider all current priorities that would be affected and how they should be handled. Before any system planning is done, a feasibility study should be conducted to determine if creating a new or improved system is a viable solution. This will help to determine the costs, benefits, resource requirements, and specific user needs required for completion. The

System Development Life Cycles (SDLC) * * * * * Tutorial 3 in a series of 6 - Overview of Software Engineering Principles 3 The system development life cycle (SDLC) follows a project through from the initial idea to the point where it is a functional system. It is a core part of the methodology that is used when defining a project. Life cycles fall into a number of different categories, iterative being the most common but they also include waterfall, spiral and chaos

proposed information system as followed: Rapid response, Quaility control, Preventive maintenance, and Reporting. This system allow housekeepers to report problems as soon as possible without waiting so that it can reduce the chance of “slippage through the cracks” if the housekeeper forgot to communicate the problem. This system also can avoid the same problem occurred again and the manager can reward the employees according to their performance based on the data which showed by the system. While Blake
