SDLC

What is SDLC?
The Software Development Life Cycle (SDLC) is a process used by software engineers to plan, build, test, and maintain software applications. It ensures that the final product meets customer requirements and is delivered on time with good quality.

Advantages of SDLC:

• Better planning and control

• High-quality output

• Reduced risks

• Clear documentation

Phases of SDLC:

1. Planning – Define project goals, time, and budget.

2. Requirement Analysis – Collect and understand user needs.

3. Design – Create system architecture and UI design.

4. Development – Write and build the code.

5. Testing – Find and fix errors (bugs).

6. Deployment – Release the software to users.

7. Maintenance – Update and fix issues after release.

Popular SDLC Models:

1.Waterfall Model– A linear and simple approach

2.Agile Model – Flexible and iterative development

3.Spiral Model – Focuses on risk analysis

4.V-Model – Testing is done parallel with development
