  • 1. ATAM (An Architecture Tradeoff Analysis Method) 1 Dr. Himanshu Hora SRMS College of Engineering & Technology, Bareilly
  • 2. An architecture Tradeoff Analysis Method  ATAM is designed to elicit the business goals for the system as well as for the architecture.  ATAM is so named because it reveals how well an architecture satisfies particular quality goals and it provides insight into how quality goals interact-that is, how they tradeoff. ATAM is a comprehensive way to evaluate a software architecture.
  • 3. Participants in ATAM  The evaluation team.  Project decision makers.  Architecture stakeholders.
  • 4. Evaluation team includes:- • Team leader • Evaluation leader • Scenario scribe • Proceedings scribe • Timekeeper • Process observer • Process enforcer • Questioner
  • 5. Stakeholders include:-  developers, testers.  users,  builders of systems interacting with this one
  • 6. Outputs of ATAM  A concise presentation of the architecture.  Articulation of business goals.  Quality requirement in terms of collection of scenarios.  Mapping of architectural decisions to quality requirements.  A set of identified sensitivity and tradeoff points.  A set of risks and non risks.  A set of risk themes.
  • 7. Conceptual flow of ATAM
  • 8. Phases of the ATAM
  • 9. Steps of the Evaluation Phase • Present the ATAM • Present Business drivers • Present Architecture • Identify architectural approaches • Generate quality attribute utility tree • Analyze architectural approaches • Brainstorm and prioritize scenarios • Analyze architectural approaches • Present results
