The V-Model is a software development methodology that provides a clear, structured approach to development and testing. It is particularly suited for projects where reliability, safety, and regulatory compliance are paramount, such as in industries like aerospace, healthcare, automotive, and finance.

The V-Model gets its name from the shape of the process flow, which resembles the letter "V". The left side of the "V" represents the stages of definition and design, while the right side represents validation and verification activities. The bottom of the "V" is the actual coding phase, where development occurs.

The V-Model continues to be a valuable methodology for projects that require high levels of reliability, safety, and compliance. Its structured approach ensures that testing and validation are deeply embedded in the development process, leading to robust and reliable software systems.
