This document specifies the means to organize and record architecture evaluations for enterprise, systems and software fields of application. The aim of this document is to enable architecture evaluations that are used to: a) validate that architectures address the concerns of stakeholders; b) assess the quality of architectures with respect to their intended purpose; c) assess the value of architectures to their stakeholders; d) determine whether architecture entities address their intended purpose; e) provide knowledge and information about architecture entities; f) assess progress towards achieving architecture objectives; g) clarify understanding of problem space and of stakeholder needs and expectations; h) identify risks and opportunities associated with architectures; and i) support decision making where architectures are involved.
