System features are implemented in a series of short, timeboxed iterations. Each iteration results in an executable release of the software. It is customary to write full text use cases during the construction phase and each one becomes the start of a new iteration.
State Transition and Interaction Overview diagrams. Transition Phase. The final project phase is Transition. In this phase the system is deployed to the target users. Feedback received from an initial release or initial releases may result in further refinements to be incorporated over the course of several Transition phase iterations. The Transition phase also includes system conversions and user training. The Product Release Milestone marks the end of the Transition phase.

The Rational Unified Process itself contains the roles, activities, artifacts, guidelines, and examples necessary for its modification and configuration by the adopting organization.
Starting in , the RUP contains several variants, or pre-packaged development cases for different types of software development organizations. This inefficient approach idles key team members for extended periods and defers testing until the end of the project lifecycle, when problems tend to be tough and expensive to resolve, and pose a serious threat to release deadlines.
The truth is that requirements usually change. With the iterative approach, you can mitigate risks earlier. As you unroll the early iterations, you test all process components, exercising many aspects of the project, such as tools, off-the-shelf software, people skills, and so on. It allows you to release a product early with reduced functionality to counter a move by a competitor, or to adopt another vendor for a given technology. Design reviews in early iterations allow architects to spot potential opportunities for reuse, and then develop and mature common code for these opportunities in subsequent iterations.
As the product moves beyond inception into elaboration, flaws are detected even in early iterations rather than during a massive testing phase at the end. Performance bottlenecks are discovered at a time when they can still be addressed, instead of creating panic on the eve of delivery. Testers start testing early, technical writers begin writing early, and so on. In a non-iterative development, the same people would be waiting around to begin their work, making plan after plan but not making any concrete progress.
What can a tester test when the product consists of only three feet of design documentation on a shelf? In addition, training needs, or the need for additional people, are spotted early, during assessment reviews. The assessment at the end of an iteration not only looks at the status of the project from a product or schedule perspective, but also analyzes what should be changed in the organization and in the process to make it perform better in the next iteration. Project managers often resist the iterative approach, seeing it as a kind of endless and uncontrolled hacking.
In the Rational Unified Process, the iterative approach is very controlled; the number, duration, and objectives of iterations are carefully planned, and the tasks and responsibilities of participants are well defined. In addition, objective measures of progress are captured. Some reworking takes place from one iteration to the next, but this, too, is carefully controlled.
Manage Requirements Requirements management is a systematic approach to eliciting, organizing, communicating, and managing the changing requirements of a software-intensive system or application. The fundamental measure of quality is whether a system does what it is supposed to do. With the Rational Unified Process, this can be more easily assessed because all stakeholders have a common understanding of what must be built and tested.
Fixing errors in requirements is very expensive. With effective requirements management, you can decrease these errors early in the development, thereby cutting project costs and preventing delays. Requirements management facilitates the involvement of users early in the process, helping to ensure that the application meets their needs.
Well-managed requirements build a common understanding of the project needs and commitments among the stakeholders: users, customers, management, designers, and testers. It is often difficult to look at a traditional object-oriented system model and tell how the system does what it is supposed to do.
This difficulty stems from the lack of a consistent, visible thread through the system when it performs certain tasks. In the Rational Unified Process, use cases provide that thread by defining the behavior performed by a system. Angga El-Barca. Surbhi Sarawagi. Krish Lohana. Manish Patil. Koushal Gadekar.
