Different phases in SDLC
1. Systems Planning: During this phase,
the project proposal is evaluated to determine its feasibility. The outcome of
this phase is a preliminary
investigation report that includes a cost-benefit analysis, a risk
assessment, and a recommendation to proceed or not.
2. Systems Analysis: During this phase,
the current system is studied, and user requirements are gathered. fact-finding is performed using techniques such as
interviews, surveys, document review, observation, and sampling. The purpose is to build a logical model of the new system The
outcome of this phase is a System requirements document that specifies what the new system should do.
3. Systems Design: During this phase, The
purpose is to create
physical model. the requirements are translated into a
detailed design that includes hardware and software specifications, database
design, and user interface design and necessary outputs, inputs, and processes are identified. programmers will use to transform the logical design
into program modules and code. The outcome of this phase is a system design
specification that serves as a blueprint for the construction phase.
4. Systems Implementation: During this
phase, the new system is constructed, programs are written, tested, and
documented, and the system is installed. The outcome of this phase is a working (functioning) system
that meets the user requirements.
5. Systems Support and Security: During
this phase, the IT staff maintains, enhances, and protects the system. The
objective during this phase is to maximize return on the IT investment.
Security controls safeguard the system from both external and internal threats.
A well-designed system must be secure, reliable,
maintainable, and scalable. The outcome of this phase is a system that
continues to meet the user requirements and is secure and reliable Fully Operational
System.
