To estimate the overall cost and schedule for the project. To produce detailed estimates for the Elaboration phase. To estimate the potential risks, to prepare the support environment for the project. The rup is risk driven; the highest risks are identified earliest, and efforts are made to mitigate or address those risks as early in the project lifecycle as possible instead of pushing them forward. The Inception phase plays the most critical role in the project and will result in the first release of the product. In such cases, significant business and requirements risks need to be carefully managed. Accordingly, for new releases or enhancements of existing products, the Inception phase becomes much shorter.

Figure 1-6, iterations achieve objectives of phase milestone. Phases need to end with accomplishment milestones, as shown. Each milestone provides a critical decision point, or a go or no-go. Chapter 14, "Phases, Activities, and Milestones discusses in detail all four phases and their respective objectives and evaluation criteria. Here, we will briefly review these phases. Please note that phases are executed in a sequence, as shown. Inception Phase, the main goal of the Inception phase is to achieve concurrence among all stakeholders on the lifecycle objectives of the project. The following are the primary Inception phase objectives: to establish the project's scope and boundary conditions. To identify the critical use cases of the system. To exhibit and demonstrate one candidate architecture.
For instance, earlier in the rup lifecycle, although there is a focus on the development of an executable build as early in the lifecycle as possible, there is a greater need to build an understanding of the business problem or opportunity. Therefore, this need, as shown in the hump chart, requires more activities from the business Modeling and Requirements disciplines to be performed earlier in the rup project lifecycle. Iterations are designed and executed with certain goals in mind. Depending upon which phase the iteration belongs to, the iteration goals are aligned to accomplish the respective gender milestone. For example, iterations for the Elaboration phase are designed such that its objectives are achieved and the lifecycle Architecture milestone is accomplished. Therefore, achievement of each iteration goal moves the project closer to achieving the respective objectives of that phase. This concept is presented. Each iteration has its own respective goals and is designed such that collectively, the iterations are executed within a given phase. These iterations achieve respective objectives of a milestone.
Each phase concludes with a major milestone, as shown. The following sections provide a brief discussion of each phase. The focus in this section is to clarify, at the process framework level, the difference between the traditional waterfall lifecycle thesis and the iterative and incremental development lifecycle as implemented by the rup. Figure 1-5, the phases and milestones of a rup project. Overview, as discussed earlier, phases are made up of iterations, and both phases and iterations are important concepts to grasp for building a concrete understanding of the rup. Disciplines play an important role in designing the iterations carried out within each phase. Although we do discuss disciplines later, let's briefly see how the rup defines the term discipline. According to the rup, "a discipline is a collection of related activities that are related to a major area of concern." Based on which phase you are in, each iteration contains activities from across different disciplines.
By the end of this section, you will look at the rup hump chart differently; you will be able to discuss why some disciplines should be there in your organization's specific rollout of rup and how phases, iterations, milestones, and disciplines are related. This chapter also discusses the importance of disciplines, phases, and iterations in iterative and incremental development. Let's now discuss these components in a little more detail. Figure 1-4, the rational Unified Process overview, phases and Milestones. The rup provides an iterative and incremental approach to developing software. This iterative and incremental development happens within iterations that occur within a structured lifecycle consisting of phases and milestones. The rup has four sequential phases: Inception, Elaboration, construction, and Transition. Each of them plays a central role in managing iterative 1 and incremental development projects using rup.

This chapter is from the book. This valuable section offers a concise explanation of the rup architecture. It starts with the popular hump chart, shown. Figure 1-4, which illustrates the overall rup architecture. This figure contains information on phases, iterations, milestones, disciplines, their inter-relationships, and the lifecycle concept. This section focuses primarily on establishing a foundation from which you will be able to achieve the most value from this book. This foundation will enable you to clearly appreciate the relationships between different components of rup architecture, as illustrated.
Several artifacts are used in a number of disciplines; for example, the risk list, the software Architecture document, and the Iteration Plan. These kinds of artifacts belong to the artifact set where they are primarily produced. Rational Unified Process rUP ) is an object-oriented and Web-enabled program development methodology. According to rational (developers. Rational Rose and the, unified Modeling Language rup is like an online mentor that provides guidelines, templates, and examples for all aspects and stages of program development.
Rup and similar products - such as Object-Oriented Software Process (oosp and the open process - are comprehensive software engineering tools that combine the procedural aspects of development (such as defined stages, techniques, and practices) with other components of development (such as documents, models, manuals. Rup establishes four phases of development, each of which is organized into a number of separate iterations that must satisfy defined criteria before the next phase is undertaken: in the inception phase, developers define the scope of the project and its business case; in the. Rup provides a prototype at the completion of each iteration. The product also includes process support for java 2 Enterprise Edition (. J2EE ) and bea webLogic ) development, and supplies an, html -based description of the unified process that an organization can customize for its own use. Getting started with use rational Unified Process.

Artifacts are used to capture and convey project information. An artifact can be any of the following: A document, such as Business Case or entry Software Architecture document. A model, such as the Use-case model or the design Model. A model element thesis ; that is, an element within a model, such as a class, or a subsystem. Models and model elements, have reports associated with them. A report extracts information about models and model elements from a tool. A report presents an artifact or a set of artifacts. Most artifacts have guidelines, which describes the artifact in more detail. To make the development of a complete software system manageable, the artifacts are organized into sets corresponding to the disciplines.
Rup methodology - tip. The project needs to be in the hands of real expert or else it may lead to an undisciplined form of development.

the development part of the can software development life cycle. The code is written for the various components and other features of the software. As you can imagine, depending on the size of the project, the number of iterations will increase. 4.0 Transition, the product moves from development to production in this phase of rup methodology. The user gets a first look at the software and is trained up. The software goes through beta testing and is assessed against the project quality plan detailed during the inception phase.
The various phases involved in developing a software within this framework are: The 4 Phases of rup.0 Inception. In this phase, the business case is prepared and night discussed. This includes business success factors (i.e. Revenue and market recognition assessment of risk, creating a project plan and use case model. The project manager will also write a project initiation document or project charter during this phase. 2.0 Elaboration, this phase is marked by mitigation of risk through proper analysis. It includes development of the basic form of project architecture and use case descriptions. The business case is revisited to revise the project risks log and ensure that managing project risk is possible.

Rup (Rational unified process) methodology is an iterative and adaptive software development framework which is promoted by the rational Software company which is now owned by ibm. The rup methodology is based around a specific team skillset, timescales and some key document models. Software organizations will customize this framework as per their needs to produce high quality software to meet the stipulated project budget and project plan. Rup methodology unifies the team which will include members from the six disciplines of software engineering. The 6 Disciplines of rup methodology. These are: There are three other disciplines which will play a supportive role. These are: Environment Setup yardage and Management, configuration and change management, project Management, rUP methodology follows an iterative approach which is used in organizing the work through a number of phases.
