Chris Tsai is the Director of DFMA Implementation Services at Boothroyd Dewhurst. He has over 25 years of engineering, change management, and leadership experience with the Eastman Kodak Company and the Rochester Institute of Technology (RIT). Most of that time was spent in the equipment product design and manufacturing portion of Kodak’s operations (i.e. digital cameras, scanners, printers, medical imaging devices, etc.). He has held positions in product & tooling design engineering, manufacturing engineering, project management, quality management, and globalization. Early in his career, he established himself as a corporate subject matter expert in Value Analysis/Value Engineering (VA/VE) and Design for Manufacture & Assembly (DFMA) and later expanded that expertise to Lean Six Sigma being certified as a Black Belt and becoming a corporate Lean Six Sigma instructor and mentor. He has developed and delivered corporate training and certification around the world and is a SAVE International certified Associate Value Specialist (AVS).

As Quality & Process Improvement Manager in Kodak’s Health Imaging Group, he led the establishment of a new Supplier Quality function driving an order of magnitude reduction in defects and scrap material costs in less than three years. As Globalization Manager, he led the Lean Six Sigma Manufacturing initiatives transforming Kodak Health Imaging’s Minnesota and Shanghai, China hardware manufacturing operations. As a DFMA sensei, he has helped teams identify over $100M in potential cost savings and avoidance.

Chris has a Bachelor’s Degree in Mechanical Engineering from Purdue University and a Master’s Degree in Manufacturing Engineering from the Rochester Institute of Technology.
