DOE training is the nuclear option of root cause analysis techniques.
We regard Design of Experiments (DOE) as the most powerful problem solving tool in the world. Our Masters have used DOE to produce 6-digit per year savings many times across a broad range of industries and applications. It's definitely worth adding to your arsenal.
One or two fun case studies provide real, physical systems allowing students to actually experience how DOE works. Advanced topics such as fractional factorial arrays, multi-level factors, Taguchi arrays, etc. are covered. Statistical software such as Minitab or SigmaXL is also used.
