Rational Unified Process (RUP)

The Rational Unified Process (RUP) is an iterative, software development methodology, firstly introduced by the Rational Software Corporation which was acquired by IBM in 2003. RUP is a disciplined approach to assign tasks within a development organization and software project teams. It was developed, to ensure the production of high quality software who could meet and exceed the needs and expectations of end-users, strictly following a predictable budget and schedule. RUP is the most popular and extensively documented refinement of the Unified Process, an iterative and incremental software development process framework. Other worth mentioning forms are the OpenUP and Agile Unified Process.
