ATAM (Architecture Tradeoff Analysis Method) is a comprehensive method to evaluate a software architecture. It elicits business goals and how well an architecture satisfies quality goals such as through tradeoffs. The evaluation team includes roles like a team leader, evaluation leader, and stakeholders. Through phases like presenting the business drivers and architecture, brainstorming scenarios, and analyzing approaches, ATAM outputs include identifying sensitivity points, risks, and mapping decisions to requirements.

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.
