Guide and Best Practices

Developed in the 1980s by Paul Rook, the V -Model was developed to improve the efficiency and effectiveness of software development. The V model is a step-by-step development process where the next phase of the development cycle only begins once the previous phase is completed. The V-Model lays a great emphasis on testing at every phase and is designed to ensure that the product is tested parallelly as it is developed.

The Phases of V-Model

Verification Phase
- Business Requirement Analysis: This involves detailed communication with the client to comprehend their exact requirements.
- System Design: This involves the entire hardware and communication setup for the product being developed.
- Architectural Design: This involves the technical and financial feasibility of the product before it is actually developed.
- Module Design: This involves developing a detailed plan for all the modules in a system.
Coding
- This involves the actual coding of the modules based on the plan developed in the previous stage. Based on the system and architectural requirements a coding language is chosen. The code is then reviewed and optimized to ensure the delivery of the best performing product.
Validation
- Unit Testing: These are tests run at the early stages to eliminate bugs that could affect product development.
- Integration Testing: This is done to check whether there is efficient communication between the internal modules of the system.
- Systems Testing: This involves the testing of the system as a whole and is done to ensure internal modules communicate effectively with the external systems
- Acceptance Testing: This is done to test a product in the end users’ environment and to check whether it is compatible with other systems in the environment.
