About Tetradian

Change-mapping was designed by Tetradian, working with JC3DVIS. 

Tetradian runs masterclasses on Whole Enterprise Architecture. which focuses on the wider picture surrounding Enterprise Architecture.

Change-mapping was designed as a response to some shortfalls in certain EA systems which tended to be focused mostly on IT. Tetradian's principal consultant developed and wrote many well respected books and articles explaining the benefits of understanding the bigger picture surrounding Enterprise Architecture. 

Visit the Tetradian website to find out more about Whole EA masterclasses and how they can help your organisation be more effective.

Tetradian has published many books about Whole Enterprise Architecture, including a brand new set of anthologies. The first of these provides overviews and commentary on how to develop a career in enterprise-architecture, business-architecture and related fields, and on the various roles that apply in those fields. It is intended to be a useful introduction for newcomers to enterprise-architecture.

This book includes about 30 posts and 30 images from the Tetradian weblog. These posts are split into two main groups:

  • Architecture as Career - offers practical guidance for anyone interested in developing a career in enterprise-architecture or any of the related disciplines.

  • Architecture Roles - describes the different roles across the overall architecture domains, what they each do, and how they link together across the whole to support effective change.
