Eric Maass worked at Motorola for 30 years as an engineer, engineering manager and director.
He was one of the originators of Six Sigma and Design for Six Sigma.
Eric later worked at Medtronic for 11 years as a senior director.
He received his bachelor's in Biology, a dual master's degree in Chemical Engineering and BioMedical Engineering, and his doctorate in Industrial Engineering....so he is either very broad-spectrum - or very confused :)
