Definition
The Systems Development Life Cycle (SDLC) is a structured process for planning, designing, developing, testing, and deploying software systems. It ensures that software solutions meet business and technical requirements effectively.
Common SDLC Models:
- Waterfall – Sequential approach with defined phases.
- Agile – Iterative, flexible, and feedback-driven.
- V-Model – Emphasizes verification and validation.
- Spiral – Risk-focused, iterative model.
Why SDLC Matters:
- Ensures quality and security standards are met.
- Helps control project costs and schedules.
- Provides a clear roadmap for software development teams.
A well-executed SDLC leads to reliable, scalable, and high-performing software solutions.
