Ivar Jacobson

Ivar Jacobson is a Swedish computer scientist known for his contributions to software engineering and development processes. He is best recognized for creating the Rational Unified Process (RUP) and for his work on object-oriented programming. Jacobson introduced the concept of use cases, which help developers understand user requirements by outlining how users interact with a system. His methods have influenced many software development practices, making them more structured and efficient. He has also been instrumental in the development of UML (Unified Modeling Language), a standard way to visualize software system designs.
