The Enterprise Unified Process extends the IBM Rational Unified Process (RUP) to address the full IT process.
The Unified Process process started in 1988 with Objectory and ended in the early 2010s when IBM sunsetted support for RUP.
Rational Unified Process (RUP) started in the mid-1990s as a process framework for object-oriented (OO) software engineering. It quickly became the dominant process in the late 1990s, but was eclipsed by agile ways of working (WoW) in the early 2000s. It was effectively retired by IBM Rational in the early 2010s.
