The V-Model is an engineering process model used for software development. It is a specialized skill that follows a specific set of phases that are sequenced in a V-shape. This model emphasizes the importance of software testing and validation at each phase of development, starting from the requirements gathering stage, through design, implementation, testing, and overall maintenance. This approach ensures that the software developed is of high quality, has fewer errors, and meets the expectations of the stakeholders. The V-Model is commonly used in industries where software quality is critical, such as aerospace, defense, and medical devices.
