The Architecture Definition Document spans all architecture domains (business, data, application, and technology) and also examines all relevant states of the architecture (baseline, interim state(s), and target). The Architecture Definition Document is a companion to the Architecture Requirements Specification, with a complementary objective: • The Architecture Definition Document provides a qualitative view of the solution and aims to communicate the intent of the architects. • The Architecture Requirements Specification provides a quantitative view of the solution, stating measurable criteria that must be met during the implementation of the architecture. It is suggested that this document reference the various deliverables in the container.
For instance, the Architecture Principles will be documented in an Architecture Principles document and that document referenced here. It may be that this container is implemented using a wiki or as an intranet rather than a text-based document. Even better would be to use a licensed TOGAF tool that captures this output. This template shows “ typical” contents of an Architecture Definition Document and can be adapted to align with any TOGAF adaptation being implemented.
