About the Book

This anthology from the Tetradian weblog demonstrates the importance of discipline and formal rigour in architectures - and what happens if the discipline fails, or the rigour is absent.

This book includes about 35 posts and 70 images from the weblog. These posts are split into two groups:

  • How Not To Fail: Concept-Critique - raises key questions about quality of formal-rigour, theory and discipline in current enterprise-architecture and beyond.
  • How Not To Fail: Method-Critique - also raises key questions and concerns about quality and reliability of method in current enterprise-architecture and suchlike.
