CheckPoint: The Phases of the System Development Process

Use the information from the reading to complete this activity.

Identify the phases of the System Development Process (also referred to as the Systems Development Life Cycle (SDLC).

Specify the activities of each phase.

The Systems Development Life Cycle (SDLC) is a conceptual model used in project management that describes the stages involved in an information system development project from an initial feasibility study through maintenance of the completed application. Various SDLC methodologies have been developed to guide the processes involved including the waterfall model (the original SDLC method), and the spiral model. Mostly, several models are combined into some sort of hybrid methodology. Documentation is crucial regardless of the type of model chosen or devised for any application, and is usually done in parallel with the development process. Some methods work better for specific types of projects, but in the final analysis, the most important factor for the success of a project may be how closely particular plan was followed.

The oldest, and the best known, is the Waterfall model methodology, which is the first SDLC method and it describes the various phases involved in System Development Process. These phases are as following:

1. Project planning, feasibility study: Planning includes establishing a high level strategy of the intended project and determining what the project goals are.

2. Systems analysis, requirements definition: Refines project goals into defined functions and operation of the intended of the system. Analyzes end-user information needs.

3. Systems design: Describes desired features and operations of the system in detail, including screen layouts, business rules, process diagrams, pseudocode and other documentation. It also includes the companies’ rules, layouts and other documentations.

4. Implementation: The real code is written here means the designs...
