Six Sigma History

Six Sigma Academy was founded in 1994 by Mikel Harry, Ph.D. who was later joined by Richard Schroeder. Both men were members of the core team that developed and utilized the principles of Six Sigma within Motorola in the mid-1980's. Dr. Harry was one of the statisticians who worked closely with Motorola engineer Bill Smithto develop the core tenets of Six Sigma. Mr. Schroeder was an operations executive on Motorola's Quality Council, and had overview responsibility for programs such as Six Sigma and The Malcolm Baldrige Quality Award.

In early 1994 Mr. Schroeder, who had since left Motorola, asked Dr. Harry to help him implement Six Sigma at Asea Brown Boveri (ABB).

Welch decided to implement Six Sigma at GE in 1996. He asked Dr. Harry and Mr. Schroeder to introduce Six Sigma to GE.

As the success of Six Sigma at GE began tobe reported, Six Sigma Academy needed a way to bring the Breakthrough Strategy® to other global corporations. Harry and Schroeder decided to form an association with Jack Finney, the founder of MPE Inc., a company that offered Lean and ISO consulting services to both public and private sector clients. In 2000, Six Sigma Academy and The Acceleration Group formally merged into one company doingbusiness as Six Sigma Academy. Mikel Harry, Rich Schroeder and Jack Finney were principal shareholders as well as directors. Mr. Finney was also involved in the operations of the Academy.

By 2002, Mr. Schroeder and Dr. Harry had desired to pull back from the day-to-day management of the Academy. After several months of transition, in early 2003, Jack and Phyllis Finney became the owners of Six...
