Worked-Examples for EA Practice
Worked-Examples for EA Practice
Decision-making in whole-enterprise architecture
About the Book
This anthology from the Tetradian weblog provides practical, real-world examples of the thinking required to tackle architecture-issues, before diving down into the specific details of implementation.
This book includes roughly thirty-five posts and seventy images from the weblog. These posts are split into two groups:
- Everyday Challenges - outlines typical processes and checks - often in step-by-step form - that are likely to be useful in tackling routine architecture-challenges.
- Problem-Cases - provides worked-examples of architecture-errors that could, will or already have caused disruption or damage, and describes what needs to be done to rectify those mistakes.
