RUP(Rational Unified Process)
Introduction
It is an iterative, agile software development methodology.
Firstly introduced by the Rational software corporation
which was acquired by IBM in 2003
It is the most popular and extensively documented refinement
of the Unified Process.
It was developed to ensure the production of high quality
software by development team in providing
guidelines,
templates
tool mentors

Phases of RUP
It Includes
I. Time Dimension
is horizontal axis that represents the dynamic aspects of process
It expresses time in terms of phases and iterations.
II. Process dimension
is vertical axis that represents the static aspects of process
It expresses workflows in terms of six core and three supporting
disciplines.

Time Dimension
Inception Phase
To establish the project’s scope and boundary conditions
To estimate the overall cost and schedule for the project
To estimate the potential risks
To produce detailed estimates for the elaboration phase
Elaboration Phase
To establish a base-lined architecture (Project Shape)
To address all architecturally significant risks
Scope and risks revised
To produce the best evolutionary prototype of
production-quality component

Time Dimension cont…
Construction Phase
To iteratively and incrementally develop a complete product
based on the base-lined architecture.
It avoids unnecessary scrap and rework through Parallelism
It minimizes development costs
Optimizes resource utilization

Transition Phase
To ensure the availability of software to end users
To validate the new system against user expectations (by beta-
testing)
To train the end users and maintainers
Deployment done in this phase

Process dimension
There are six core and three supporting disciplines:
1. Business Modelling Workflow
The business context (scope) of the project should be
outlined
2. Requirements Workflow
Define all potential requirements of the project.
3.Analysis & Design Workflow
Takes requirements and transforms them into a design.

4. Implementation Workflow
majority of actual coding takes place.
5. Test Workflow
Testing of all kinds takes place within this workflow.
6. Deployment Workflow
constitutes the entire delivery and release process,
ensuring that the software fits the customer interest.

Building Blocks of RUP
Workers, the ‘Who’
group of responsible individuals who are working together
in order to produce artifacts(products).
Activities, the ‘How’
A unit of work that a worker is to perform
Artifacts, the ‘What’
represents any tangible output that emerges from the
process.
Workflows, the ‘When’
represents a diagrammed sequence of activities, in order to
produce observable value

RUP Best Practices
Develop Software Iteratively
Manage Requirements
Use Component-Based Architectures
Visually Model Software
Verify Software Quality
Control Changes to Software

Advantages of RUP
Allows for the adaptive capability to deal with changing
requirements
Emphasizes the need of accurate documentation
It is easier to control the risks
04/19/2021 RUP(Rational Unified Process)
Disadvantages of RUP
It heavily relies on proficient and expert team members
It emphasis on integration throughout the development process
RUP is a fairly complicated model
