Lessons From Definitive Screening Designs

Stu Janis, Lean Six Sigma Coach, 3M Company

Definitive screening designs (DSDs) represent an exciting new approach for screening many factors with considerably fewer runs and better resolution than classic fractional factorial designs. This talk will cover lessons learned during the design and analysis of several DSDs at 3M. Lessons range from theoretical (fake factors to generate extra runs for additional power and lower correlations among two-factor interactions, differences between JMP 12 and JMP 13 approaches to DSD analysis) to practical (pay attention to how the experimenters collect and report their data).
