The correct answer is: A. System Development Life Cycle
A system development life cycle (SDLC) is a framework for planning, designing, building, testing, and deploying an information system. It is a phased approach that helps to ensure that all aspects of the system are considered and that the system is developed in a logical and orderly manner.
Requirements are the essential features and functionality that a system must have in order to meet the needs of its users. They are typically documented in a requirements specification document, which is used as a reference throughout the SDLC.
Requirements also serve as an evaluation checklist at the end of the development project. This means that the system can be evaluated against the requirements to ensure that it meets all of the needs of its users.
The other options are not correct because they are not related to requirements or the SDLC.
- A CASE tool is a computer-aided software engineering tool that can be used to automate some of the tasks involved in the SDLC.
- Phased conversion is a strategy for deploying a new system in which the system is gradually rolled out to users over a period of time.
- Success factors are the key elements that contribute to the success of a project.
- Move of the above is not a correct option.
