QualPro, Inc. is a Knoxville, Tennessee-based management consultancy that uses multivariable testing to simultaneously test a large number of ideas to improve business processes or performance. The firm gathers ideas from the client organization’s staff at all levels, eliminates those that don't meet its criteria, and evaluates the remaining ideas through experiments that test 20-30 variables simultaneously.
The company was founded in 1982 by Dr. Charles Holland, based on his work reducing defects in urethane foam used in nuclear weapons. He was influenced by prior work by British statisticians to improve anti-aircraft shells in World War II, the book The Design of Experiments, and his work supporting seminars with Edwards Deming. The company has designed experiments to determine the layout of the front page of the National Enquirer, to reduce defects and costs in DuPont's manufacturing plants and to assess the optimal format for Lowe's' newspaper advertising inserts.
