  6. RUP Demos For free online demos, white papers, etc., go to: http://www.rational.com/tryit/rup/seeit.jsp

  7. Today’s agenda Topic Duration • RUP Demo 30 minutes • RUP Structure 45 minutes • *** Break 10 minutes • RUP Project Management 30 minutes • RUP Jeopardy 45 minutes • Assignment 2 Explanation 10 minutes • Quiz #2 25 minutes

  8. Chapter 3Static Structure: Process Description • Workers • What have these been renamed in RUP v2001 to better align with industry usage? • How many roles can a given individual play on a project? • Activities • What are the 3 types of steps? • Artifacts • How do artifacts relate to deliverables? • What are the 5 types of artifacts? • What are the 5 information sets? • Workflows • What are the 9 core process workflows? • Guidelines • What are the 2 types of guidelines?

  9. Workers • A Worker is a role played by an individual or a team. • Example: • Stakeholder • Systems Analyst • Designer • Test Designer • Project Manager Note: Workers renamed Roles in RUP 2001

  10. Mapping of Roles to Workflows

  11. Mapping of Roles to Workflows (cont.)

  12. Mapping of Roles to Workflows (cont.)

  13. Artifacts • A piece of information that is produced, modified or used by a process. • Artifacts are the tangible products of the project • Examples: • A use-case model • A document such as a business case • Source Code • Executable code

  14. Artifacts - Examples Product

  15. Activities • An Activity is a unit of work that a worker may perform. • Examples: • Plan an interaction performed by Project Manager • Find use cases and actors • Review the design • Execute a performance test

  16. Workflows One development cycle Workflow: A sequence of activities that produces some result of observable value

  17. Additional Process Elements • Guidelines - are rules, recommendations, or heuristics that support activities and steps. • Templates - are models or prototypes of artifacts • Ex. Word template for Vision Document • Tool mentors - are a means of providing guidance by showing you how to use a specific software tool (Similar to wizards) • Concepts - Separate material that describe some of the reasons and background on a specific topic

  18. Analysis Guideline Use-Case Template Rose Tool Mentor RUP Model Notation

  19. Development Cycle Phase Iteration Activity Activity (Individual) Product • Take this diagram and add: • iteration • workflow • artifact • worker/role • step • guideline • template • example • tool mentor

  20. Rational’s View of Best Practices • Use Iterative Development • Manage Requirements • Use Component Architectures • Model Visually • Continuously Verify Quality • Control Change

  21. UML Components • Multiple Views • Precise Syntax and semantics • Include • Use-Case Diagrams • Class Diagrams • Object Diagrams • Component Diagrams • Deployment Diagrams • Activity Diagrams • State Chart Diagrams • Collaboration Diagrams • Sequence Diagrams

  22. Today’s agenda Topic Duration • RUP Demo 30 minutes • RUP Structure 45 minutes • *** Break 10 minutes • RUP Project Management 30 minutes • RUP Jeopardy 45 minutes • Assignment 2 Explanation 10 minutes • Quiz #2 25 minutes

  23. Rational’s View of Best Practices • Use Iterative Development • Manage Requirements • Use Component Architectures • Model Visually • Continuously Verify Quality • Control Change

  25. Planning an Iterative Project • Two Levels of Plans • Phase Plan • Iteration Plan

  26. Planning an Iterative Project • Two Levels of Plans • Phase Plan • Iteration Plan

  27. Project Management Workflow • Risk • Risk identification • Risk mitigation • Metrics • Goal-driven • First derivative • SQERT • Iterations • 6 +/- 3 • Scope of an iteration

  30. Phase Duration/Budget What if: • No architecture in place? • Second generation of existing product, keep existing architecture? • Short time to deliver? • Complex conversion and deployment?
