According to the Ivar Jacobson International, the Essential Unified Process will be launched in this year in June. I am very interested in the variations of Rational Unified Process (RUP) that take an agile approach to software development unified process, so this is great news. There is another similar project I'm following closely: The Agile Unified Process (AUP) of Scott W. Ambler. And there is, of course, the Basic Unified Process (BUP), from IBM-Rational itself, which donated to the Eclipse Process Framework a simplified version of the RUP as open source.
