Architecture Definition Document is one of the TOGAF deliverables you can create with the TOGAF software.

This document describes the baseline and target enterprise architecture, and gap analysis for your project. It contains the core architectural artifacts created during a project.

The Architecture Definition Documents produces in phase B, C and D span 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 Documents are a companion to the Architecture Requirements Specification, with a complementary objective:

  • The Architecture Definition Documents provide 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.
