A Brief Overview of The Rational Unified Process - RUP Methodology


In the article chosen this week, a review of the Rational Unified Process (RUP) is presented, the authors described the RUP methodology as an iterative process, which can be used for software development, and help developers accomplish any software development project, on time. A software engineering process, which can be delivered through a web-enabled, searchable knowledge base, is also known as the Rational Unified Process. The history and practices involved in RUP, are discussed, in the article chosen this week, as well as the advantages and disadvantages of the RUP methodology.

 Whenever appropriate, a comparison with other software development methodologies is also made, in the article chosen this week. As an object-oriented and web enabled system development model, RUP is able to provide examples for all aspects and states of the development of a software as well as guidelines and templates, which can help a developer achieve any software development project. The RUP methodology, combines the stages, techniques and practices, of software development, as well as documents, diagrams, models, manuals, help files, code samples, final source code etc…; which are all components of the software development life cycle, in order to help software developers, complete any software development project.

A variant of RUP, according to the author, which is tailored for enterprise level software development, is known as Enterprise Unified Process (EUP). The System Development Life Cycle (SDLC) methodologies, are extended by the EUP, to address factors which are at the enterprise-level, and could prevent a software development team, from developing a software. When a software development project, is at the enterprise level, it is considered to be huge project, and its successful development, will depend on how well, developers are familiar with the factors, just mentioned.

As a software engineering process, the RUP methodology, provides a disciplined approach, in order for a development team, to have a task and a responsibility assigned to them. The production of high-quality software, is ensured when the RUP methodology is utilized by a development team. Also the needs of the end-users, must be met, and the budget and schedule should not be exceeded in an RUP methodology environment. The IBM Rational® Software developed and maintains the Rational Unified Process, as a software development methodology.

According to the author, RUP has three perspective known as the dynamic perspective, which over time shows the phases of RUP. The other perspective of RUP is the statistics perspective, which is made of things that work together to change the dynamic processes of RUP. The last perspective of RUP is the practice perspectives, which promotes good practices, which can be used, during the software development process. Through previous work and experience, the effectiveness and usefulness of the practices, are well known.

The phases of RUP are: inception phases, which is where the project and the business case is defined. During the elaboration phase, developers are able to analyze the needs of the project, in greater detail and the foundations of the architectural structure of the software, is also studied. The application is designed and source code, are created during the construction phase, by the development team. The system is delivered to the users during the transition phase, by the development team.
