Statistical Design Institute, LLC, focuses on applied research, development, and effective deployment and implementation of Design for Six Sigma (DFSS) and Systems Engineering. The company was formed in 1999 by senior engineers with years of collective engineering experience and years of Six Sigma/DFSS Black Belt and Master Black Belt experience.

Recognizing the need to apply the principles of Six Sigma and System Engineering to product development efforts, they applied their experience in the aerospace, defense, and commercial business sectors to build upon traditional Six Sigma approaches and developed a unique, 'product driven', integrated DFSS/System Engineering training and a suite of easy-to-use software tools.
