Software Development Life Cycle (SDLC) is a framework that defines tasks performed at each step in the development process.
Originated in the 1960s, SDLC is a structured, standardized set of processes for developing and maintaining business solutions.
From inception to completion, it details out; how to plan, build, and maintain specific software.
It aims to:
- Deliver high-quality system
- Work efficiently with the existing and planned infrastructure
- Maximize productivity
- Provide strong management controls
- Lower the cost the development
SDLC’s phases are:
- Requirement Gathering
- Designing
- Coding
- Testing
- Maintenance
Developers must adhere to these steps as each phase uses the results of the previous ones
SDLC separates “what” and “how” in terms of doing tasks and creating outputs.
Information is organized in a hierarchical manner so that every user can access information quickly.
Why SDLC?
- Project Tracking and control
- Increased visibility
- Enhanced Development speed
- Improved client relation
- Decreased the project risk
To manage the project complexities, number of SDLC models was created like waterfall, incremental, Agile, Prototype, etc.
The method of implementing SDLC varies vastly between methodologies.
SDLC is a crucial consideration before the actual software development process.
