Published almost two decades back, this book provides a prescriptive approach that can be used to create top two layers of John Zachman’s Enterprise Architecture (EA) Framework (as published in year 1987). It provides a ten-phase process, which is phase-wise described in ten chapters. Each of these ten chapters describes the phase by providing steps involved. For each step, the author has mentioned the purpose, deliverables & tasks and guidelines. He has also provided sample documents for business model, data architecture, application architecture and technology architecture, as appendixes. This is a good how-to book for EA and hence every EA professional should consider reading this book.
