4 TOGAF ADM Guide-Through From Visual Paradigm

Provides a high-level, aspirational view of the end architecture product. The purpose of the vision is to agree at the outset what the desired outcome should be for the architecture, so that architects can then focus on the critical areas to validate feasibility. This video shows you how to develop an Architecture Vision document.

Architecture Vision

Purpose

The Architecture Vision is created early on in the ADM cycle. It provides a summary of the changes to the enterprise that will accrue from successful deployment of the Target Architecture. The purpose of the Architecture Vision is to provide key stakeholders with a formally agreed outcome. Early agreement on the outcome enables the architects to focus on the detail necessary to validate feasibility. Providing an Architecture Vision also supports stakeholder communication by providing a summary version of the full Architecture Definition.

Content

Typical contents of an Architecture Vision are:

Problem description:
Stakeholders and their concerns
List of issues/scenarios to be addressed
Objective of the Statement of Architecture Work
Summary views necessary for the Request for Architecture Work and the Version 0.1 Business, Application, Data, and Technology Architectures created; typically including:
Value Chain diagram
Solution Concept diagram
Mapped requirements
