Rational Unified Process Fundamentals Copyright © Rational Software, all rights reserved 2 Objectives: Implementing RUP  Understand the purpose of the Environment Workflow  Understand the role of the Process Engineer  Understand the purpose of the Development Case  Explore how to configure RUP  Explain strategies for implementing a process

Rational Unified Process Fundamentals Copyright © Rational Software, all rights reserved 3 Characteristics of RUP  RUP is a framework  RUP is iterative  RUP’s Activities and Artifacts may vary in degrees of formality  RUP is very complete

Rational Unified Process Fundamentals Copyright © Rational Software, all rights reserved 4 A Tailorable Process  Can be used in whole or in part  Can be tailored to fit in an existing process The Development Case in RUP captures how the project should work and helps develop an organization-wide reusable process framework.

Rational Unified Process Fundamentals Copyright © Rational Software, all rights reserved 10 Environment: Artifact Overview

Rational Unified Process Fundamentals Copyright © Rational Software, all rights reserved 11 Configuring a Process  The process framework is adapted to the needs and constraints of the adopting organization  The result is documented in a Development Case.

Rational Unified Process Fundamentals Copyright © Rational Software, all rights reserved 12 Development-Organization Assessment Determines needs and constraints of the adopting organization by considering:  The business context  Contract work versus commercial development  The size of the software development effort  The degree of novelty  Has the development organization ever built a similar system?  The type of application  Embedded real time verses individual IT application  The current development process  Organizational factors (e.g., skills, attitudes)  Project complexities

Rational Unified Process Fundamentals Copyright © Rational Software, all rights reserved 13 Classification of Projects by Complexity

Rational Unified Process Fundamentals Copyright © Rational Software, all rights reserved 14 Development Case The Development Case  Describes the project’s process:  Phases and milestones  Which artifacts to use  How to use artifacts  Which activities to perform  Additional activities  How to work in each discipline  Iteration Plan descriptions

Rational Unified Process Fundamentals Copyright © Rational Software, all rights reserved 27 Implementation Approaches: Fast

Rational Unified Process Fundamentals Copyright © Rational Software, all rights reserved 28 Implementation Approaches: Careful

Rational Unified Process Fundamentals Copyright © Rational Software, all rights reserved 29 Common Mistakes and Solutions  Trying to change too much  Failing to manage scope  Failing to manage risk  Getting bogged down in new techniques or technologies  Implement change incrementally, driven by risk and feedback  Focus on delivering essential value  Systematically attack risk through a series of iterations  Focus on, measure, and reward results (product delivery), not intermediate deliverables

Rational Unified Process Fundamentals Copyright © Rational Software, all rights reserved 30 Other Common Mistakes  Bowing to schedule pressure without cutting scope  Viewing quality as a QA function  Regarding productivity as a coding problem  Replan or rescope early; start negotiating ASAP  Assess and reward quality from the beginning  Make everything testable (architectural compliance, feature compliance, etc.)  Focus on architecture and reuse as specific, measurable objectives

Rational Unified Process Fundamentals Copyright © Rational Software, all rights reserved 31 Best Practices for Process Implementation  Assess the development organization  Employ progressive process improvement  Do not scale up too early  Get buy-in from stakeholders  Anticipate resistance; devise a strategy  Involve process engineers in development  “A process description is not a process”  Transfer knowledge  Set expectations  Do not hype the process
