what is SDLC? what are the different stages in SDLC?
Answer Posted / cj
SDLC means Systems Development Life Cycle or Software
Development Life Cycle. A Systems Development Life Cycle
(SDLC) adheres to important phases that are essential for
developers, such as planning, analysis, design, and
implementation, and are explained in the section below. A
sequence of stages in which the output of each stage
becomes the input for the next. These stages can be
characterized and divided up in different ways, including
the following:
1. Project planning, feasibility study:
Establishes a high-level view of the intended project and
determines its goals.
2. Systems analysis, requirements definition:
Defines project goals into defined functions and operation
of the intended application. Analyzes end-user information
needs.
3. Systems design:
Describes desired features and operations in detail,
including screen layouts, business rules, process diagrams,
pseudocode and other documentation.
4. Implementation:
The real code is written here.
5. Integration and testing:
Brings all the pieces together into a special testing
environment, then checks for errors, bugs and
interoperability.
6. Acceptance, installation, deployment:
The final stage of initial development, where the software
is put into production and runs actual business.
7. Maintenance:
What happens during the rest of the software's life:
changes, correction, additions, moves to a different
computing platform and more. This, the least glamorous and
perhaps most important step of all, goes on seemingly
forever.
