RUP Terms And Definitions

Cycle: it includes all the activities that are executed during project time.

Phases: Each cycle in the RUP is broken down into a sequence of four phases, called Inception, Elaboration, Construction, and Transition.

4

RUP Terms And Definitions

Iteration: Inside each phase there may be one or more iterations. Software is developed in each iteration,

Milestone: The point at which an iteration formally ends; corresponds to a release point.

5

RUP Terms And Definitions6

Workflow: is a sequence of activities that produces a result of observable value.

Discipline is a collection of activities that are related to a major "area of concern" within the overall project

What is RUP?

An approach to assigning and managing tasks and responsibilities in a development organization

Focused on high-quality software that meets the needs of its end users within a predictable schedule and budget

A process framework that can be tailored to specific organization or project needs

RUP is a methodology for delivering projects in a maximum performance manner.

8

Key Aspects of RUP Risk-driven process

Iterations are planned based on high priority risks

Use-case driven development Use cases are used as the basis of the entire

development process

Architecture-centric design

Architecture is the primary artifact to conceptualize, construct, manage, and evolve the system

9

RUP 6 Best practices

Develop Software Iteratively

Manage Requirements

Use Component-Based Architecture

10

RUP 6 Best practices

Visually Model Software Promotes consistency and unambiguous

communication of development information

Continuously Verify Software Quality Identify defects early

Control Changes to Software

Create and release a tested baseline at the end of each iteration

RUP Architecture

Dynamic Structure Dynamic aspect deals with the lifecycle or time

dimension of a project.

Static Structure How RUP elements co-work together.

Expressed in term of core disciplines.

13

RUP Architecture

Each cycle contains 4 phases

Inception

Elaboration

Construction

Transition

14Dynamic Structure

RUP Architecture15

Inception phaseObjective:

Understand what to build. Identify key system functionality.

A initial use-case model (10% -20%) complete. Determine at least one possible solution.

One or several prototypes. Understand the costs, schedule, and risks of the

project. An initial risk assessment.

Decide what process to follow and what tools to use. A project plan

This phase helps you determine the project feasibility , what customer want and how will you do that

16

Lifecycle Objective Milestone

Milestone: Actual expenditures versus planned expenditures.

time

Inception Elaboration Construction Transition

First Major

Milestone

17

Elaboration phase Deeper Requirement

understanding At least 80% complete use-case

modelnon functional requirements

Architect consideration. A Software Architecture

Description. An executable prototype.

Risk mitigation and Accurate Cost A revised risk list and a revised business case.

Development Case refinement A development plan for the

overall project

Objectives:

The goal of the Elaboration phase is to define and baseline the architecture of the system in order to provide a stable basis for the design and implementation effort in the Construction phase.

18

Milestone : Lifecycle Architecture

Is vision Stable? Is architecture stable?

This milestone tell help to determine if project plan, vision , architectureAre good enough to achieve project goals? If not reconsider it very seriously

time

Inception Elaboration Construction Transition

Major

Milestones

19

Construction Phase

Minimize development costs

The software product integrated on the adequate platforms.

The user manuals.

A description of the current release.

Construction is about cost-efficient development of a complete product—an operational version of your system—that can be deployed in the user community

Objectives:

20

Milestone : Initial Operational Capability

Is this product release stable and mature enough to be deployed in the user community?

Are actual resource expenditures versus planned expenditures still acceptable?

time

Inception Elaboration Construction Transition

Major

Milestones

Is used to determine:Whether the product is ready to be deployed into a beta test environment by answering (among others) the following questions

21

Transition Phase

Once the product has been given to the end user, issues usually arise that require you to develop new releases, correct some problems, or finish the features that were postponed.

22

Milestone: Product Release

Is the user satisfied?

Static Aspect of RUP

A process describes who is doing what, how, and when. The Rational Unified Process is represented using four primary modeling elements: Activity (How) Worker (Who)

Artifact (What) Workflows (when)

Project Management Business Modeling Requirements Analysis and Design

Implementation Test

25

Static Process Elements

Roles or workers (who)Defines the person or a team that should do the work

Activity (how)Describes a piece of work a worker performs

Artifact (what)A piece of information that is produced, modified, or used by an activity

Workflow (when)Specifies when a set of related activities is performed, by which workers, producing some artifact, which provides some observable value to the project

RUP workflow A Workflow is a grouping of activities that are often

performed "together" to produce a specific result.

32

RUP workflow Core workflows:

1. Business modeling workflow

2. Requirements workflow

3. Analysis & Design workflow

4. Implementation workflow

5. Test workflow

6. Deployment workflow
