The rational unified process (RUP) is an iterative software development process framework created by the Rational Software Corporation, a division of IBM since 2003. [1] RUP is not a single concrete prescriptive process, but rather an adaptable process framework, intended to be tailored by the development organizations and software project teams that will select the elements of the process ...
Profile of a typical project showing the relative sizes of the four phases of the Unified Process. The unified software development process or unified process is an iterative and incremental software development process framework. The best-known and extensively documented refinement of the unified process is the rational unified process (RUP).
The rational planning model is a model of the planning process involving a number of rational actions or steps. Taylor (1998) outlines five steps, as follows: [ 1 ] Definition of the problems and/or goals;
In software engineering, a software development process or software development life cycle (SDLC) is a process of planning and managing software development. It typically involves dividing software development work into smaller, parallel, or sequential steps or sub-processes to improve design and/or product management .
A RUP ‘hump’ is a plot of effort spent over time during a particular Rational Unified Process (RUP) discipline. The RUP hump chart consists of a collection of humps for all RUP disciplines. This diagram was created in 1993 during a workshop on architecture and process [1] and was inspired by work by Grady Booch [2] and Boehm.
Ivar Jacobson was born in Ystad, on September 2, 1939.He received his Master of Electrical Engineering degree at Chalmers Institute of Technology in Gothenburg in 1962. After his work at Ericsson, he formalized the language and method he had been working on in his PhD at the Royal Institute of Technology in Stockholm in 1985 on the thesis "Language Constructs for Large Real Time Systems".
Cybernetics and modernism inspired the related theories of rational process and systems approaches to urban planning in the 1960s. [58] They were imported into planning from other disciplines. [ 58 ] The systems approach was a reaction to the issues associated with the traditional view of planning. [ 59 ]
The agile unified process distinguishes between two types of iterations. A development release iteration results in a deployment to the quality-assurance and/or demo area. A production release iteration results in a deployment to the production area. This is a significant refinement to the rational unified process.
