Analysis and Design Rational Unified Process

The Rational Unified Process® or RUP® product is a software engineering process. It provides a disciplined approach to assigning tasks and responsibilities within a development organization. Its goal is to ensure the production of high-quality software that meets the needs of its end users within a predictable schedule and budget. The RUP has two dimensions: the horizontal axis represents time and shows the lifecycle aspects of the process as it unfolds the vertical axis represents disciplines, which group activities logically by nature. The first dimension represents the dynamic aspect of the process as it is enacted, and it is expressed in terms of phases, iterations, and milestones. The second dimension represents the static aspect of the process: how it is described in terms of The graph shows how the emphasis varies over time. For example, in early iterations, we spend more time on requirements, and in later iterations we spend more time on implementation. The RUP is now taken as the standard Unified Process (UP) by most of the software industries. A discipline is a collection of related activities that are related to a major 'area of concern' within the overall project. The grouping activities into disciplines is mainly an aid to understanding the project from a 'traditional' waterfall perspective-typically, for example, it is more common to perform certain requirements activities in close coordination with analysis and design activities. Separating these activities into separate disciplines makes the activities easier to comprehend but more difficult to schedule.
