On Theory And Enterprise Architecture [Leanpub PDF/iPad/Kindle]

This anthology from the Tetradian weblog explores notions of theory in enterprise-architecture and the like, from mainstream IT-centric views to whole-enterprise architectures and beyond.

This book includes about 40 posts and 65 images from the weblog. These posts are split into four groups:

Theory: Patterns - reviews the underlying concepts and definitions for a wide range of architecture concerns and patterns.
Theory: Technology - assesses how problems in technology and architecture often arise from a poor grasp of underlying theory.
Theory: Science - considers how we need to use science itself to test the science we use in our architectures and more.
Theory: Scale - explores how theory itself can break down at different scales, and will need to be adapted to work well in those contexts.
