Rational Unified Process And Extreme Programming
Abstract: The IBM Rational Unified Process(r) (RUP(r)) is a complete process for software development framework that comes with several out-of-the-box instances. The methods that come from RUP vary from lightweight addressing the needs of small projects with short product cycles to more comprehensive processes addressing the broader needs of large or distributed teams. Projects of all kinds and sizes have made use of RUP. This whitepaper explains the ways in which RUP can be applied in a way that is light on small projects. This white paper will explain how to implement extreme programming (XP) within the larger framework of an entire project. Inception For new development efforts, Inception is crucial. Before the project can move forward, it is necessary to take care of critical business and requirements risks. The Inception phase for projects that enhance an existing system is less time-consuming but it's still about making sure Software Development Team that the project is viable and worth the effort. Inception is when you make the case for the creation of the software. Inception is when you create the vision. It's a comprehensive explanation of the system. It provides the system's explanation to everyone. It may also explain what it will be used for, the reasons it should not be used, the features it should have, and what constraints it will have to meet. 1 XP includes three phases: Exploration and Commitment. These are not well mapped to RUP phases so we choose to use the four RUP phases to define the process exist. The Vision could be extremely brief, perhaps only two or three paragraphs. The Vision often has the most crucial functions that the software has to offer to the customer. The RUP identifies four essential inception-related activities as o Define the scope of the project. Create and plan the business case. o Synthesize candidate architecture. Create the project's environment. Elaboration The Elaboration phase aims to develop a base architecture that will be used to design the entire system. This will serve as a solid foundation for the majority of the planning and implementation tasks in the Construction phase. The structure evolves as a result of an examination of the most critical requirements (those which have a significant impact on the design of the system) and an assessment of risk. The architecture's stability is assessed through an architectural prototype or two. RUP focuses on system architecture, and software architecture for software-intensive systems. Using component architectures is one of the six most effective methods of software development that are outlined in RUP and recommends that you spend time developing and maintaining the architecture. This effort reduces the risk of a rigid and fragile system. XP is an example of a "metaphor" of architecture. This metaphor captures a portion of architecture, while the rest develops organically as code is written. XP assumes that architecture emerges from the most basic layout and constantly refactoring the code. You should finish at the very least three of these tasks when you are preparing a project: o Establish the baseline architecture, validate it, and establish the foundational architecture o Refine the Vision. o Create and baseline iteration plans for the Construction phase. Construction The goal of Construction is to finish the development of the system. The Construction phase is, in some sense an industrial process where you emphasize managing resources and directing operations to optimize cost, schedules, and quality. In this regard, management's attitude shifts from Inception and Elaboration to Construction and Transition, where intellectual property is created. Each Construction version has three fundamental tasks: Managing resources and controlling the process Develop and test the components. Examine the iteration. Transition The focus of Transition is to ensure that software is readily available to its users. The transition phase involves testing the product prior to its release and minor adjustments on the basis of feedback from users. This phase in the lifecycle requires that users provide feedback to help fine-tune the product, as well as configure, install, and resolve usability problems. The most important transition activities include: o Finalize end-user support material. o To test the product in a customer environment. o You can fine tune the product based upon feedback from customers. • Deliver the finished product to the final user. You can produce several artifacts during the Transition phase. It is possible to create multiple artifacts if your product is available in the future versions. It will be possible to pinpoint features and correct defects to be fixed for the next release. The most significant artifacts to any project are: o Deployment Plan o Release Notes Training Materials and documentation. Digest Software development is more than just writing code. Software development should encompass all the activities necessary to provide quality services for customers. The process does not have to be complex. This article has shown you how to create a simple, but complete procedure. We focused on the most significant actions and artifacts pertinent to your particular project. If it helps to reduce risk, you can do an activity or create an artifact. Use as much, or as little and formality as you require to your team members and your organization. RUP and XP aren't necessarily the same. You can combine techniques from both to create a process which delivers superior software faster than you are currently in a position to. Robert Martin describes the dX process.8 This is an example of a RUP-compliant process. A good software process incorporates industry-proven best practices. These top practices have been proved to work in real-world software development businesses. The XP method is receiving a lot of attention at present. It is code-centric, and promises minimal overhead and maximum efficiency. There are numerous techniques within XP that warrant consideration and adoption in the right circumstances. XP focuses on the story, test, and code. It discusses plans in a certain amount however, it treats the recording of plans as lightly. XP suggests that you make other things like "do a CR design with a few cards or sketch out some UML ..."" or "Don’t create artifacts or documents ...", however, you should treat them with a passing glance. RUP suggests making only the things that are useful and essential as you create and review your development plan. It also defines what those things could be. RUP covers all aspects of software development. It is based on most effective practices established on hundreds of projects. We encourage research and creation of new techniques which lead to better practices. We look at the possibility of incorporating innovative best practices into RUP as they become accessible.
