The Rational Unified Process (RUP) What is it?

The Rational Uni f ied Processis a software engineering

process and a product.

It provides a disciplined approach to assigning tasks andresponsibilitieswithin 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 Rational Unified Process (RUP)

Diagram 1.1 shows the overall architecture of the RUP,

which 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 process

components, disciplines, activities, workflows, artifacts,

and roles

Phases and Iterations

The software lifecycle is broken into cycles, each cycle working ona new generation of the product. RUP divides one development

cycle in four consecutive phases: Inception phase

Elaboration phase

Construction phase

Transition phase

Each phase is concluded with a well-defined milestone- a point intime at which certain critical decisions must be made, andtherefore key goals must have been achieved.

Each phase in RUP can be further broken down into iterations. An

iterationis a complete development loop resulting in release(internal or external) of an executable product, a subset of thefinal product under development, which grows incrementally fromiteration to become the final system.

Phase 2: Elaboration

The primary objective is to mitigate the key risk items identified

by analysis up to the end of this phase. The elaboration phase

is where the project starts to take shape. In this phase the

problem domain analysis is made and the architecture of

the project gets its basic form.

Phase 4: Transition

The transition phase consists of the transfer of the system

to the user community

It includes manufacturing, shipping, installation, training,

technical support and maintenance

Development team begins to shrink

Control is moved to maintenance team

Alpha, Beta, and final releases

Software updates

Integration with existing systems (legacy, existingversions, etc.)

Dynamic Structure of RUP

The first (horizontal) dimension represents the dynamic aspect

of the RUP process expressed in terms ofcycles, phases,

iterations, and milestones.

In the RUP, a software product is designed and built in a

succession of incremental iterations. This allows testing and

validation of design ideas, as well as risk mitigation, to occur

earlier in the lifecycle.

An iterative process breaks the development cycle into a

succession of iterations.

A development cycle is divided into a sequence of four phases

that partition the sequence of iterations. The phases are

inception, elaboration, construction, and transition.
