Expert Solution & Answer
Explanation of Solution
Systems Development Life Cycle (SDLC):
- SDLC is also referred to as application development life cycle that is used in systems engineering, information systems and software engineering.
- It is used to describe a process for planning, creating, testing, and deploying an information system.
- It generally applies to a range of hardware and software configurations, as a system can be composed of either hardware or software or a combination of both.
- There are mainly four phases in the SDLC cycle as follows:
- System planning and selection
- System analysis
System design - System implementation and operation
Systems planning and selection:
- Systems planning and selection is the first phase in the SDLC, where a detailed study is performed to identify why the new system is required and how the project team will work in order to develop a new system.
- This phase performs two activities as follows:
- Project initiation
- During this step, the project team describes the business values that the system will add to the organization in terms of revenue or cost reduction.
- This involves in generating a system request which will advise how the system should be built in order to add values to the organization.
- In order to find out the economic and organizational impact of the system, a feasibility study is conducted before the second phase of SDLC.
- During feasibility analysis, feasibility of the system is checked in terms of technical feasibility, economic feasibility and organizational feasibility. Then, these reports are presented to the approval committee.
- Project management
- In this step, the project manager develops a project plan which is a detailed description of how the project team will complete the project on time and will deliver a system that meets the requirement of the organization.
- Project initiation
