1. Waterfall SDLC.
2. Agile SDLC.
3. V-Model SDLC.
4. Hybrid SDLC.
Waterfall Software Development Life Cycle (SDLC) is old model focuses on structured and well documented software development process. It is non-iterative approach allowing multiple projects to run in parallel. Waterfall SDLC falls into following catagories.
Requirement
Design
Development
Testing
Acceptance
Maintenance
2. Agile SDLC.
Agile Software Development Life Cycle (SDLC) follows an adaptive, fast process approaches. It consists of multiple iteration usually
(1-4 weeks).
Iteration 1
Design
Development
Test
Iteration 2
Design
Develop
Test
Iteration 3
Design
Develop
Test
Iteration 4
Design
Develop
Test
3. V-Model SDLC.
V-Model Software Development Life Cycle (SDLC) is also structured, well documented and discipline which is a rigorous and measurable processes. It is predictive and largely used by complex projects:
Requirement Analysis Acceptance
Testing
System Design System
Testing
Architecture
Design Integration
Testing
Model Design Unit Testing
Development
Hybrid Software Development Life Cycle (SDLC) is an approach that companies are adapting hybrid of Waterfall and V-Model or Agile software development process that suits their environment. Within the same company, one team or product line is following a particular process whereas others following different processes. This could happen when companies are likely to transitioning from one model to another model.
