Lean transformations are decidedly more challenging when the math is inconsistent with lean principles misapplied, or just plain wrong. Math should never get in the way of a lean transformation, but instead should facilitate it. Lean Math is the indispensable reference for this very purpose. A single, comprehensive source, the book presents standard and specialized approaches to tackling the math required of lean and six sigma practitioners across all industries-seasoned and newly minted practitioners alike.Lean Math features more than 16 thoughtfully organized entries. Ten chapters cover system-oriented math, time, the -ilities (availability, repeatability, stability, etc.), work, inventory, performance metrics, basic math and hypothesis testing, measurement, experimentation, and more. Two appendices cover standard work for analyzing data and understanding and dealing with variation. Practitioners will quickly locate the precise entry(ies) that is relevant to the problem or continuous improvement opportunity at hand. Each entry not only provides background on the related lean principles, formulas, examples, figures, and tables, but also tips, cautions, cross-references to other associated entries, and the occasional Gemba Tale that shares real-world experiences. The book consistently encourages the practitioner to engage in math-assisted plan-do-check-act (PDCA) cycles, employing approaches that include simulation and trystorming. Lean Math truly transcends the numbers by reinforcing and refreshing lean thinking for the very purpose of Figuring to Improve. About the Author
Partner and COO at The Murli Group, Mark R. Hamel is an award-winning author, blogger, and speaker. He has played a transformative role in lean implementations across a broad range of industries including aerospace and defense, automotive, building products, business services, chemical, durable goods, electronics, insurance, healthcare, electric power, and transportation services. Mark has successfully coached lean leaders and associates at both the strategic and tactical levels.
In his 19-year pre-consulting career, Mark held executive and senior positions within operations, strategic planning, business development, and finance. His lean education and experience began in the early 1990s when he conceptualized and helped launch what resulted in a Shingo-Prize-winning effort at the Ensign-Bickford Company.
Mark holds a B.S. in mathematics from Trinity College in Hartford, Conn., M.S. in professional accounting from the University of Hartford where he graduated with honors, and a M.A. in theology from Holy Apostles College and Seminary, summa cum laude. He is a CPA in the state of Connecticut and is dual APICS certified in production and inventory management (CPIM) and integrated resource management (CIRM). Mark was a national Shingo Prize examiner for eight years, has helped develop exam questions for the ASQ/AME/SME/Shingo Lean Certification, and is Juran certified as a Six Sigma Black Belt.
A gifted author, educator, and communicator, Mark wrote the SME published and 2010 Shingo Research and Professional Publication Award-winning book, Kaizen Event Fieldbook: Foundation, Framework, and Standard Work for Effective Events. He is the founder and primary contributor of the lean blog, Gemba Tales, co-founder of the Lean Math blog, and was a regular columnist for Quality Digest. Mark is also a faculty member of the Lean Enterprise Institute.
Michael OConnor, Ph.D. is a lean six sigma implementation consultant. He has led or co-led a number of lean six sigma launches that have produced hundreds of millions of hard dollar benefits. In recognition of this achievement and his transformative work, Dr. OConnor was awarded the Master Black Belt of the Year award by the International Quality and Productivity Center.
Michael is a passionate educator and communicator. His interests span a broad spectrum and he has given workshops on topics ranging from Diracs Large Number Hypothesis to the integration of lean and six sigma at the National Health Service. Given this scope, it is not surprising that Dr. OConnor has worked with leading organizations in check processing, healthcare, insurance, IT services, semiconductor manufacturing, server manufacturing, telecommunications, and the Federal Government.
Michael is a life-long learner and holds B.S. degrees in electrical engineering and physics, and a M.S. and a Ph.D. in physics. He is a certified Master Black Belt and a Shingo Prize Examiner.
