In 1996, Natalie was an instrumental team member in the Lean transformation of a GM facility in Matamoros, Mexico. The team was awarded the 1996 GM President's Council Honors for the project. While working with General Motors, she had multiple opportunities to visit and learn from New United Motor Manufacturing, Inc. (NUMMI). Natalie has trained, coached, mentored, and rolled up her sleeves to implement Lean practices, whether working in a company or volunteering at a food bank. She received a Bachelor of Mechanical Engineering from the University of Dayton in 1988 and a Master of Manufacturing Systems Engineering from the University of Michigan in 1992. She is a graduate of Coach University and Corporate Coach University. Natalie is also a Six Sigma Black Belt and a Global Leadership Executive Coach.

The I-Emerge toolbox includes executive and personal coaching, group facilitation, Lean methods, public speaking, and Organizational Development tools and assessments. She is a passionate people person, who lives her life with the convictions that "there is always a better way" and "change won't happen without the people."Bruce Williams strives for perfection and added value as a scientist, educator, consultant, and entrepreneur. Leveraging the Lean principle of standardized work, this is his third For Dummies book in three years, having previously coauthored the best-selling Six Sigma For Dummies in 2005 and the Six Sigma Workbook For Dummies in 2006.
