RUP Best Practice #3: Use component architectures. RUP development is based on the use and reuse of component modules or subsystems that serve a certain function. The use of component architectures lessens complexity as well as the relative size of the application.
During RUP inception and elaboration, various architectural elements must be defined and baselined. There are four distinct architectures in RUP: 1) business-specific, 2) application-specific, 3) middleware-specific, and 4) system software-specific. The system software refers to more infrastructure-related components such as operating systems.
Rational Unified Best Practices: A Primer for the Project Manager If you are an application development project manager, or if you are looking to become one, you will very likely be asked if you have ever used RUP, or Rational Unified Process.
Various activities take place during these phases: modelling, analysis and design, implementation, testing and application. The Rational Unified Process (RUP) is iterative, meaning repeating; and agile.
The main goal of RUP is to create high quality software with a predictable budget and time frame. RUP is supported by a variety of tools, supporting change and configuration management, creating automated documentation, performance tracking, and other tasks.
The fundamental purpose of the Rational Unified Process is to provide a model for effectively implementing commercially proven approaches to development, for use throughout the entire software development life cycle.
This methodology is highly recommended for producing high quality software within time and budget constraints. This method may be used for large or small teams, and may be modified to incorporate agile type methodologies.
Rational Unified Process (RUP) is a software development process for object-oriented models. It is also known as the Unified Process Model. It is created by Rational corporation and is designed and documented using UML (Unified Modeling Language). This process is included in IBM Rational Method Composer (RMC) product.
Advantages and Disadvantages of Rational Unified Process It supports incremental build the software product. It provides proper documentation of the software product. It helps to use the resources efficiently. It helps to identify issues early in the process life cycle.
One difference is that RUP is a framework for organizations and teams, while the Agile method is more intended for a product team with strict/clear guidelines. RUP uses its predefined phases more specifically and these phases show what you do in the different phases.
The benefits of RUP It allows you to deal with changing requirements regardless of whether they are coming from the customer or from the project itself. It emphasizes the need for accurate documentation. It forces integration to happen throughout the software development, more specifically in the construction phase.
RUP provides a structured approach to iterative software development, dividing the process into four milestones: Inception, Elaboration, Construction, and Transition.

A RUP project has four phases: inception, elaboration, construction, and transition; as in Figure 4 below. Each phase has one or more iterations and is completed with a milestone. At that point, the project progress is assessed, and major decisions are made based on that progress.
Rational Unified Process (RUP) is an object-oriented and Web-enabled program development methodology. According to Rational (developers of 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 (which is an IBM product) is an iterative-incremental process consisting of six sub-processes or workflows: Each trip around the loop is called an iteration.

To address risk, RUP organizes a product release into four phases: initiation, elaboration, construction, and transition. During initiation, project planners set the initial scope and budget for the project.
Unified Process is based on the enlargement and refinement of a system through multiple iterations, with cyclic feedback and adaptation. The system is developed incrementally over time, iteration by iteration, and thus this approach is also known as iterative and incremental software development.
The objective of implementation is to construct the full system. This is where components are tested and released.
In the construction phase of the Rational Unified Process (RUP), the software system is constructed in its entirety. The emphasis is on the development of components and other features of the system. The majority of coding also takes place in this phase. In this production process, the emphasis is on managing costs and means, as well as ensuring quality. Results from the production phase include:
Rational Unified Process (RUP) is an agile software development method, in which the life cycle of a project, or the development of software, is divided into four phases. Various activities take place during these phases: modelling, analysis and design, implementation, testing and application.
The objective of analysis and design is to show how the system is realised in the implementation phase. It should meet all requirements, be robust, and execute all its tasks as described in the use case. This model design functions as a blueprint for the rest of the process.
The objective of requirements is to describe what the system should do and how it should function. Both the user and the developer should agree on the requirements as described in the first phase. Everything is included in a vision document. After that, a use case is developed.
As can also be seen in the RUP visualisation, testing already starts in the first phase. Normally, a product will already have to be completed by then. That is because this involves prototypes and test models.
This is where the project begins to take shape. The objective of the elaboration phase is to analyse products and to lay a foundation for the future architecture. Results of the elaboration phase include:
There are four distinct architectures in RUP: 1) business-specific, 2) application-specific, 3) middleware-specific, and 4) system software-specific. The system software refers to more infrastructure-related components such as operating systems. Of the four architectures, the business-specific architecture is the one that may most easily be eliminated.
The benefit of RUP is that change is expected, and the team should understand that requirements must always be reassessed. The project manager must constantly be communicating any requirements changes to all stakeholders and participants, as this will be of utmost importance to gaining final acceptance for each iteration and ultimately the final product.
One or more iterations can occur with each of the four RUP phases, each iteration concluding with a milestone. In the inception phase, the milestone is an idea. In elaboration, the milestone is the architecture. In construction, the milestones are the internal executable releases. In the transition phase, the milestone is the finished software product.
For the Project Manager: The project manager must guide the project team to divide a development project into manageable RUP iterations. At each stage of the resulting iterations, the project manager needs to identify possible risks and take action during the current iteration to try to remediate that risk. Lowering the project’s overall risk profile is preferable to carrying the risk over to the next iteration.
For the Project Manager: The RUP project manager needs to be an effective change manager. Both RUP and the PMBOK highlight change management as an important discipline. In a software development project, the project manager can try to enforce change management to track different components in the development process but this can be difficult as they may be considered within the scope of the development manager rather than the project manager. In addition, many developers do not want to take the time to log entries into a spreadsheet or tracking system. It is best to employ a separate tool or assign the role of controlling component changes to certain people.
RUP development is based on the use and reuse of component modules or subsystems that serve a certain function. The use of component architectures lessens complexity as well as the relative size of the application. A system that reuses well-tested architectural components is less prone to variability and more robust as well. The use of component based architectures usually results in fewer dependencies between code modules and provides more flexibility when building additional functionality and feature sets during the next iteration.
An iteration is defined as a distinct sequence of activities with an established plan and evaluation criteria, resulting in an executable operable release. This methodology makes it possible to develop a pre-defined set of working software in iterations. The RUP initiation, elaboration, construction, and transition phases can all be iterated.
RUP stands for Rational Unified Process. It is a popular and effective object-oriented software development process. RUP methodology is modified at Rational software and is widely practiced and adopted by various industries. RUP methodology can be a lightweight process that addresses the requirements of small projects to a more comprehensive process addressing the needs of large projects. As it performs early and continuous documentation of the urgent and probable risks by proper planning and keeping follow up, it helps in migrating the risks at early phases of software development. This methodology uses visualization methods like UML to build the models graphically to understand and ease the system’s complexity. For designing test cases, this methodology uses use cases.
RUP methodology is built on six best practices which are as follows
There are 9 workflows of RUP methodology in which 6 are core process, and 3 are supporting the process.
There are four phases involved in RUP – Inception, Elaboration, Construction, and Transition. Let’s discuss these phases one by one in detail.
Control changes : Any changes occurred to requirements must be managed, and their effect on software should be tracked.

Elaboration: Elaborate means refinement. This phase aims to perform a detailed analysis of the problem. It constitutes of requirements, analysis, and design phases. It eliminates the highest risk elements of the project. Use case model is 80% complete. Additional requirements in this phase capture the nonfunctional requirements. It also captures the requirements that are not related to the specific use case. An executable architecture model is developed. The development plan for the whole project, including iterations and evaluation criteria for each iteration, also specifying the process to be used.
The RUP creates and maintain models - instead of producing a large amount of paperwork, this method creates models - semantically rich representations of the software system your team is developing
There are six fundamental best practices that make RUP suitable for a wide range of projects worldwide:
A processed product - the development team for RUP is working closely with customers, partners, groups organizations to ensure that the process is constantly updated
The disadvantages of RUP 1 It mostly relies on the ability of experts and professionals to assign the activities to individuals who should then produce pre-planned results in the form of artifacts. 2 The integration in development process can also have an adverse impact on some more fundamental activities during the stages of testing 3 Although RUP has delivered excellent results, especially in software development, it is a rather complex method which makes its implementation challenging, particularly for smaller businesses, teams or projects.
Like most methodologies, RUP lifecycle is broken into four main phases (cycles), each phase working on a new generation of the product:
Manage requirements - describes how to organize and keep track of functionality requirement, documents, tradeoff, decisions and business needs
For example, TAP University (Technology as Promised) is an online learning management system. Their aim was to extend the face-to-face training and boost their online offerings to corporate and public customers and students.
