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.

Participants in ATAM

The evaluation team. Project decision makers. Architecture stakeholders.

Evaluation team includes:-

• Team leader • Evaluation leader• Scenario scribe• Proceedings scribe• Timekeeper• Process observer• Process enforcer• Questioner

Stakeholders include:-

developers, testers. users, builders of systems interacting with this one

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.

Conceptual flow of ATAM

Phases of the ATAM

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
