Winston W. Royce

Winston W. Royce was a computer scientist known for his work on software development processes. In 1970, he introduced the concept of a structured, phased approach to software engineering, which later became the foundation of the Waterfall Model. This model emphasizes completing each development stage—requirements, design, implementation, testing, and maintenance—in sequence, aiming for clear progress and organization. However, Royce also noted the importance of iteration and feedback, which are key to successful projects. His work helped shape modern software engineering practices by balancing structured planning with the need for adaptability.
