The Unified Process (UP) was first developed by a company called Rational, which is now owned by ...

Agile Unified Process has been a methodology which integrates Agile philosophy into the Unified Process. It is based on the following principles:
1 . Your staff knows what they're doing. People aren't going to read detailed process documentation, but they will want some high-level guidance and/or training from time to time. The AUP product provides links to many of the details, if you're interested, but doesn't force them upon you.
2 . Simplicity. Everything is described concisely using a handful of pages, not thousands of them.
3 . Agility. The Agile UP conforms to the values and principles of the Agile Alliance.
4 . Focus on high-value activities. The focus is on the activities which actually count, not every possible thing that could happen to you on a project.
5 . Tool independence. You can use any toolset that you want with the Agile UP. My suggestion is that you use the tools which are best suited for the job, which are often simple tools or even open source tools.
6 . You'll want to tailor this product to meet your own needs. The AUP product is easily tailorable via any common HTML editing tool. You don't need to purchase a special tool, or take a course, to tailor the AUP.
However, there is now a new movement called Disciplined Agile Delivery (DAD) which is replacing AUP. A main objective of DAD is to be able to scale AUP for very large projects. DAD provides a more organized or structured approach to Agile methods.

TY so very much
