What is Agile Unified Process (AUP) ?

Rational Unified Process, when simplified, gives rise to AUP or Agile Unified Process. Its developer – Scott Ambler, describes it as a simple and very easy to understand methodology for development of application software for business. The agile unified process makes use of agile concepts and techniques but remains true to its origin i.e., the Rational Unified Process. Various agile techniques are employed by Agile Unified Process for developing software:
> Test driven development (TDD)
> Agile modelling (AM)
> Agile change management
> Database refactoring

All these techniques help AUP in delivering its 100 percent productivity. In 2011 the AUP was considered to be 1 percent of the whole agile methodology. In 2012 DAD or Disciplined Agile Delivery Framework superseded the AUP. Since then most people have stopped working on Agile Unified Process. AUP is different from RUP in the sense that it works only on 7 principles:
> Modelling: Involves understanding about how the business is organized around the software and the problem domain of the project, and then identifying a feasible solution for addressing the problem.
> Implementation: The model is transformed in to executable code and basic testing i.e., unit testing is performed on this code.
> Testing: An objective evaluation is carried out for ensuring that the artefact is of high quality. Testing is done for rooting out the defects and validating whether the system works as desired or not. It also includes verification of the requirements met.
> Deployment: The delivery plan for the system is laid out and executed so that the product reaches the customers.
> Configuration management: Managing the access to various artifacts of the system includes tracking the various versions at regular intervals of time, managing and controlling the changes in them.
> Project management: It includes directing the activities of the project to the right track. These activities include risk management, assigning tasks to people, tracking their progress, coordinating with people for ensuring that the system is delivered on time. This is also for making sure that the project is completed within budget.
> Environment: Involves providing continuous guidance i.e., standards and guidelines and tools for ensuring process is going on right track.

The agile unified process follows certain philosophies as mentioned below:
> The team knows what it is doing: People don’t find it convenience to read highly detailed documentation. Timely training and good guidance is accepted by all. An AUP provides links to a number of details if you want, but it does not force you.
> Simplicity: The documentation is kept as simple as possible without going into too much of detail.
> Agility: For maintaining agility, the AUP should conform to the principles and values mentioned in the agile manifesto and agile alliance.
> Emphasizing on high – value activities: Only the activities that affect the project are actually considered. Rest of the activities are not counted.
> Choice of tools: In Agile Unified Process any toolset can be used. However agile experts often recommend using simple tools appropriate for the project.
> The agile unified process can be tailored specific to the needs of your project.

There are two types of iterations in agile unified process as mentioned below:
> Development release iteration: For deployment of the project to demo – area or quality assurance.
> Production release iteration: For deployment of the project to production unit.

These two iterations are a result of refinement of RUP. The RUP’s modelling, requirement and analysis disciplines re encompassed by the disciplines of agile unified process. Even though modelling constitutes an important part of agile process, it is not the dominating factor.
