Meet The Team

Charlie Protzman

President & CEO

In November of 1997, Charles Protzman formed Business Improvement Group, LLC (B.I.G.). B.I.G. is located in Baltimore, Maryland and specializes in implementing lean thinking principles and the Lean Business Delivery System – LBDS and the BASICS training and problem solving methodology.

Charles has over 27 years experience in Materials and Operations Management. He spent 13 ½ years with AlliedSignal, now Honeywell, where he was an Aerospace Strategic Operations Manager and the first AlliedSignal Lean Master. He has received numerous special-recognition and cost-reduction awards. Charles was an external consultant for DBED’s Maryland Consortium while he was with AlliedSignal. He had input into the resulting World Class Criteria document and assisted in the first three initial DBED World Class Company Assessments. Charles has taught students in Lean Principles and Total Quality from all over the world.

Charles has spent the last 20 years implementing successful lean product line conversions, kaizen events, administrative business system improvements (transactional lean) across the U.S. He is following in the footsteps of his grandfather, who was part of the Civil Communications Section (CCS) of the American Occupation. prior to Deming’s 1950 visit to Japan. C.W. Protzman Sr. surveyed over 70 Japanese Companies in 1948. Starting in late 1948, Homer Sarasohn and C. W. Protzman Sr. taught top executives of prominent Japanese Companies an 8 week course in American Participative Management and Quality techniques in Osaka and Tokyo. Over 5,100 top Japanese executives had taken the course by 1956. Many of the lessons we taught the Japanese in 1948 are now being taught to Americans as “lean principles”. The lean principles had their roots in the U.S. and date back to the early 1700s and later to Taylor, Gilbreth and Henry Ford. The principles were refined and expanded by Shigeo Shingo and Taiichi Ohno at Toyota. Modern day champions, Jim Womack and Dan Jones, are now carrying them on in a book called Lean Thinking and Seeing the Whole.

Charles participated in numerous Benchmarking and Site visits including a two-week trip to Japan in June 1996 where he worked with Hitachi in a kaizen event. He is a Master facilitator and trainer in TQM, Total Quality Speed, Facilitation, Career Development, Change Management, Benchmarking, Leadership, Systems Thinking, High Performance Work Teams, Team Building, Myers Briggs Styles Indicator, Lean Thinking and Supply Chain Management. He also participated in Baldridge Examiner and Six Sigma Management Courses. He was an Assistant Program Manager during “Desert Storm” for the Patriot missile-to-missile fuse development and production program.

Charles has a BA and MBA from Loyola College in Maryland.
