System Analysis & Design, Phase IV SDLC 4 Objective of Phase IV: The System Development Process Phase IV of the SDLC is the Implementation Phase . The implementation phase is the development of all parts of the system, including software, documentation, and the new operating procedures, that were designed in the design phase. To be successful in the implementation phase we will manage the programming, assign the tasks based on the experience of the staff, and coordinate these activities according to the schedule. We will use test planning, which determine different methods of testing based on what part of the system we need to evaluate. These methods are unit testing, integration tests, systems tests, and acceptance testing. It is very important to fix any bugs in the system prior to utilization; the cost of trying to fix errors after the fact is much greater. The documentation needed consists of both system documentation, and user documentation. Three types of user documentation are needed. Reference documents, are used to perform a specific task and are usually in the form of online help. Procedure manuals are used to perform business tasks, and tutorials on how to use the system. Finally, we will documentation navigation controls. These are indexes, links to other pages, table of contents, and other intelligent agents to help users to perform functions, commands, and explain terms used in the new system. The implementation phase is the transition to the new system. We will develop a migration plan, which tells us specifically what activities are performed and by whom. A conversion strategy will be selected describing what parts of the system will be switched over, when its to take place, and how much of the system to convert at a time. We will focus on training the individuals to use the system, and set up a system support to help people use the system. Then 2

This may involve making changes needed by a business requirement or a fix, or patch to correct a problem previously undetected. Lastly, a project assessment will be performed. This is a two-step process in which the team will review the project plan to analyze the progress and look for improvements. In addition, a system review to analyze the feasibility studies, and decides if the new system has realized the expected value. CD Selections: What They Did Right
