Lean Dynamics Research offers publications, training, and consulting services on lean dynamics as a way to conquer the uncertainty and constant change that are increasingly undermining business performance and profitability.

The concept grew from a government-industry research study led by Stephen A. Ruffa, aimed at determining if Toyota's lean manufacturing practices could make the F-35 fighter aircraft more affordable. Ruffa published his findings showing the potential for a 25 percent savings by controlling variability in his award-winning book, Breaking the Cost Barrier.  While applying key elements to Defense supplier programs for hundreds of millions of dollars in savings, he studied how successful corporations go even further by harnessing the forces of uncertainty. Ruffa introduced the underlying concept of lean dynamics in his book, Going Lean.


Founded in 2008 by Stephen A. Ruffa, Lean Dynamics Research continues to advance the principles and practices of lean dynamics through ongoing research, and providing access to world-class support to further your organization's shift to responsive, innovative capabilities.

Ruffa's diverse background as an aerospace engineer, a business researcher, and a management consultant working across functional areas with a wide range of clients has equipped him to speak to the desires and frustrations of people across your organization.  As a keynote speaker at government, industry, and academic forums he is experienced in articulating complex principles as well as the concrete steps for achieving lean dynamics goals.
