This book was written for two purposes—to popularize the important emerging field termed Lean Systems Engineering, and to serve as a reference text for the first major product created under it: Lean Enablers for Systems Engineering (LEfSE).
Balance between technical and business success is one of the critical aspects of high-quality Systems Engineering. Regretfully, during the past decade, in some government programs inadequate incentives tended to throw the balance off. Namely, system or mission assurance was incentivized at the expense of budget and schedule. This book describes how Lean Thinking is applied to Systems Engineering to achieve both technical and business successes.
Lean Thinking, or simply Lean, has been applied in many domains, including manufacturing, supply chain management, product development, administration, accounting, healthcare, and government, in each case creating significant, well-documented benefits. Lean dramatically reduced car development and production times and costs while increasing product quality and stakeholder satisfaction, and became a standard practice in most manufacturing industries.
Lean Systems Engineering should be regarded as the process of amending the well-established and sound traditional Systems Engineering process with the wisdom of Lean Thinking, rather than replacing Systems Engineering with a new body of knowledge. Most emphatically, Lean Systems Engineering does not mean “less systems engineering,” but rather better ...
