V-Model
The V-Model is a linear, sequential approach to software development that is based on the idea of “verification and validation.” It emphasizes the importance of verifying the software at each stage of the development process, and of ensuring that the software meets the specified requirements.
The V-Model includes the following phases:
- Planning: This phase involves defining the goals and objectives of the software, and creating a plan for developing it.
- Analysis: This phase involves gathering and analyzing information about the needs and requirements of the software.
- Design: This phase involves creating the design and architecture of the software.
- Implementation: This phase involves developing the software according to the design.
- Testing: This phase involves testing the software to verify that it meets the specified requirements and functions correctly.
- Deployment: This phase involves installing the software in its intended environment and making it available to users.
- Maintenance: This phase involves providing ongoing support and updates to the software.
The V-Model is a well-defined and structured approach to software development, and is well-suited to projects with well-defined requirements and a stable environment. It is particularly useful for ensuring that the software meets the specified requirements and functions correctly.
