Agile unified process (AUP) is a simplified version of the rational unified process (RUP) developed by Scott Ambler. It describes a simple, easy to understand approach to developing business application software using agile techniques and concepts yet still remaining true to the RUP. The AUP applies agile techniques including test-driven development (TDD), agile modeling (AM), agile change management, and database refactoring to improve productivity. In 2011 the AUP accounted for one percent of all the agile methodologies used. In 2012 the AUP was superseded by disciplined agile delivery (DAD). Since then work has ceased on evolving AUP.

Discipline

Unlike the RUP, the AUP has only seven disciplines :

Philosophies

The Agile UP is based on the following philosophies:

Releases

The agile unified process distinguishes between two types of iterations. A development release iteration results in a deployment to the quality-assurance and/or demo area. A production release iteration results in a deployment to the production area. This is a significant refinement to the rational unified process.
