Organizes all the steps into a detailed plan describing the series of events into detailed plan describing the series of events required to begin using the system or application in the production or live environment and details the necessary computer and software. 2. Normally, the person who is responsible for implementing program requirements also takes responsibility for preparing the plan. It is therefore unnecessary to continue discussing what is to be made during the implementation phase. Training Is most effective when hands on instruction is provided. Businesses and organizations use various types of information systems to support the many processes needed to carry out their business functions. Systems design is the process of defining the architecture, modules, interfaces, and data for a system to satisfy specified requirements. It is the most crucial phase in the development of a system. Several manuals are prepared: a user’s manual, a reference manual, and an operator’s maintenance manual. In the design phase the SDLC process continues to move from the what questions of the analysis phase to the how . All users of the new system or application must receive training. Learning to identify what should be an entity, what should be a number of entities, and what should be an attributeof an entity takes practice, but there are some good rules of thumb. structure of the components you will build. Based on the user requirements and the detailed analysis of a new system, the new system must be designed. The nature of the steps within the design phase of the SDLC is different, depending on whether the organization intends to purchase software or design the software in-house. It covers different topics such as grid sizes, gutters and how to mix them. When commercially available software is being implemented, three levels of testing are recommended.
