Characteristics of the Process
The Rational Unified Process is an iterative process. For simple systems, it would seem perfectly feasible to sequentially define the whole problem, design the entire solution, build the software, and then test the end product. However, given the complexity and sophistication demanded of current systems, this linear approach to system development is unrealistic. An iterative approach advocates an increasing understanding of the problem through successive refinements and an incremental growth of an effective solution over multiple cycles. Built into the iterative approach is the flexibility to accommodate new requirements or tactical changes in business objectives. It also allows the project to identify and resolve risks sooner rather than later.models rather than paper documents. Modelsespecially those specified using the UMLprovide semantically rich representations of the software system under development. They can be viewed in multiple ways, and the information represented can be instantaneously captured and controlled electronically. The rationale behind the Rational Unified Process's focus on models rather than paper documents is to minimize the overhead associated with generating and maintaining documents and to maximize the relevant information content.architecture-centric. The process focuses on the early development and baselining of a software architecture. Having a robust architecture in place facilitates parallel development, minimizes rework, and increases the probability of component reuse and eventual system maintainability. This architectural blueprint serves as a solid basis against which to plan and manage software component-based development.use case-driven. The Rational Unified Process places strong emphasis on building systems based on a thorough understanding of how the delivered system will be used. The notions of use cases and scenarios are used to align the process flow from requirements capture through testing and to provide traceable threads through development to the delivered system.The Rational Unified Process supports object-oriented techniques . Rational Unified Process models supports the concepts of objects and classes and the relationships among them, and they use the UML as its common notation.The Rational Unified Process is a configurable process. Although no single process is suitable for all software development organizations, the Rational Unified Process is tailorable and can be scaled to fit the needs of projects ranging from small software development teams to large development organizations. The Rational Unified Process is founded on a simple and clear process architecture that provides commonality across a family of processes, and yet can be varied to accommodate various situations. Contained in the Rational Unified Process is guidance about how to configure the process to suit the needs of an organization.The Rational Unified Process encourages objective ongoing quality control and risk management . Quality assessment is built into the process, in all activities and involving all participants, using objective measurements and criteria. It is not treated as an afterthought or as a separate activity. Risk management is built into the process, so that risks to the success of the project are identified and attacked early in the development process, when there is time to react.
