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

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
