  1. The Rational Unified Process EECS810: Software Engineering

  2. What is the Rational Unified Process?

  3. Static structure • The Rational Unified Process model is built on three entities: roles, activities, and artifacts • Workflows relate activities, artifacts, and roles in sequences that produce valuable results

  4. Roles, activities, artifacts

  5. Individuals can play multiple roles

  6. Example of a workflow

  7. Dynamic structure: incremental and iterative development • An incremental and iterative process breaks a development cycle into a succession of iterations • A development cycle is divided into a sequence of four phases that partition the sequence of iterations: inception, elaboration, construction, and transition

  8. From sequential to an iterative cycle

  9. Activities across one development cycle

  10. Benefits of an iteration approach • Accommodates changes in requirements and in implementation strategy • Confronts and mitigates risks as early as possible • Allows the development organization to grow, to learn, and to improve • Focuses on real, tangible objectives

  11. Architecture View • System architecture is used in the Unified Process as a primary artifact for conceptualizing, constructing, managing, and evolving the system under development • Architecture is a complex concept that is best represented by multiple, coordinated architectural views • An architectural view is an abstraction of a model that focuses on its structure and its essential elements

  12. Typical iteration plans • Inception phase: to define the project vision and the business case • Elaboration phase: to build an architectural prototype • Construction phase: to implement the system

  13. Defining the product vision and the business case

  14. Building an architectural prototype

  15. Implementing the system

  16. Summary • Rational Unified Process, or RUP, is a configurable software development process platform that delivers practices and a configurable architecture • Enables the developers to select and deploy only the process components they need for each stage of their project
