The material presented in this book is focused on the details of the classic systems engineering process and the role of the systems engineer. The systems engineering process described has been used successfully in both DoD and commercial product development for decades. We have tried to describe this time-proven process at a level of detail that makes it logical and understandable as a tool to use to plan, design, and develop products.This book provides a basic, conceptual-level description of engineering management disciplines that relate to the development and life cycle management of a system. For the non-engineer it provides an overview of how a system is developed. For the engineer and project manager it provides a basic framework for planning and assessing system development.The first part introduces the basic concepts that govern the systems engineering process and how those concepts fit the Department of Defense acquisition process.The second part introduces the systems engineering problem-solving process, and discusses in basic terms some traditional techniques used in the process.Part three discusses analysis and control tools that provide balance to the process.Part four discusses issues integral to the conduct of a systems engineering effort, from planning to consideration of broader management issues.
