When conducting an ATAM (Architecture Tradeoff Analysis Method) evaluation, the assessment team typically creates three key artifacts: the concrete quality tree, a description of quality scenarios, and a list of architectural risks. The quality tree is a detailed representation of quality attributes specific to the architecture being evaluated, which provides context for the scenarios. Quality scenarios are detailed, measurable descriptions of desired behaviors and responses to various conditions in the system. Finally, identifying architectural risks involves assessing potential points of failure or weaknesses in the system's architecture. These artifacts collectively help in thoroughly evaluating the architecture's ability to meet its quality requirements.
