John D. McDowall is a specialist in the architecture, design, integration, and testing of enterprise information and data analysis systems. He also conducts independent research in the fields of architecture and system engineering. John has over 20 years of experience, including his current position as the lead architect for a major system-of-systems effort within the US Department of Defense. Over the years he has learned what does and does not work, and he has developed the approach in this book as a result of the lessons he has learned solving real-world problems. He thinks it will be applicable to many other enterprise architecture efforts.After graduating from the US Naval Academy, John spent 11 years on active duty in the Marine Corps in a variety of positions. Since leaving active duty he has worked as a contractor doing IT systems development and integration for a variety of projects in the logistics, command and control (C2), and intelligence communities.
