From theory to practice in enterprise-architecture

Connecting ideas to solve practical challenges

About the Book

"Theory informs practice; practice reinforms theory". This anthology from the Tetradian weblog explores how theory and practice support each other, in the transition from initial plan to real-world implementation of an architecture.

This book includes about 35 posts and 45 images from the weblog. These posts are split into two groups:

- *From Theory* - outlines some essential theory and guiding-principles for working on enterprise-architectures and more.

- *To Practice* - provides practical guidance on common issues that can arise during development for various types of architecture.
