Summary of Expertise:

Listed with other top experts in: 

Expert specializes in application and training of product and process design improvement using the Taguchi experimental design technique. As an independent consultant and trainer he has been serving the manufacturing industries world wide since establishing his own business in 1987. His primary focus is helping clients solve technical and production related problems through experimental investigation.

Since early 1980's, while employed with automotive industry in Detroit, Michigan, USA area, Expert has devoted much of his time helping the area industry learning and applying the Taguchi methods of experimental designs. Toward this goal, he has authored three textbooks and developed a software pacakge for design and analysis of the Taguchi experiments.

Specific areas where Expert can support your manufacturing process studies are:

Project Definition - Identifying projects with higher return on investment (ROI) and defining SYSTEM boundaries clearly, are important to project success.

Experiment Planning - Structured discussions to assure that "no stone is left un-turned" is necessary for effective outcome. We can facilitate the team discussions to determine project OBJECTIVES and key VARIABLES (Factors to study).

Experiment Layout - Fewer experiments that produce most information is the guiding principle. Based on planning discussions, we can prescribe plans that include test recipes and data collection instructions.

Running Planned Tests - Conducting test true to the plan is essential. If needed, we are available to help you conduct test with accurate parameters.

Analysis of Results - Objective and statistically valid analyses often reveal hidden factor behavior. We can evaluate test results to determine practicable conclusions and estimate expected performance improvement with confidence interval.

Selected Consulting Examples:
  • The following are testimonials from clients with whom Expert provided consulting services:-"Faced with the complex nature of our manufacturing process data analysis, we recently retained Nutek, Inc. to facilitate a few of our process problem studies. Based on methods prescribed and guided by the principal consultant, Expert, I was able to identify process parameters that produced significant improvement in performance. More importantly, the unique structured approach to work with the project team allowed me to methodically investigate and understand our process performance to a greater extent. Overall, my experience with Nutek, Inc. in study of our production problem has been highly satisfactory and cost effective. In addition to application consulting service, we trained many of our engineering and quality professionals using the seminar by Nutek on Product and Process Design Improvement. Based on my experience, the Nutek 4-day seminar with application workshop has done an effective/outstanding job of preparing me for immediate applications to projects. Using the methodologies taught in the class, I have been able to apply the skills and carry out many successful experiments."
  • "I would like to express our satisfaction for the excellent Design of Experiment seminar which you provided at the John Deere Dubuque Works this spring. At the conclusion of the seminar we received very good feedback on the level of instruction and in particular your enthusiasm and breadth of knowledge on the subject matter.While positive feedback at the conclusion is important, the true test of a good class is whether or not the materials presented will change the way we do our business. I'm very happy to report that several engineers have incorporated the Design of Experiment approach into their engineering toolbox and have made decisions based upon its output. Because of our successful usage of the Taguchi-based design of experiment methodology, I like to extend to you an invitation for another seminar in Dubuque this spring."Thank you for your service and look forward to seeing you again next year.Brian J. Rauch Manager, Advanced Research and Development, John Deere Industrial Equipment Division, Dubuque, Iowa.
  • "Ford Powertrain Operations has been doing business with Expert and Nutek, Inc. since August of 1989. We were involved in purchasing the Qualitek-4 software site license for all Ford employees worldwide to automate our design of experiments. We have sponsored more than 20 onsite four day seminar/workshops training to cover 400 employees. Expert's teaching of the Taguchi approach and his focus on the application method has provided a practical approach to meet our needs. Our use of the Qualitek-4 software automates experiment layout and perform complex calculations to speed our experiment designs with effective solutions. Expert's consulting services also been helpful to solve several challenging experiments. We look forward to continuing our relationship with Expert to assist Powertrain Operations in our continuous improvement efforts."
  • "I would like to take this opportunity to thank you for the excellent instruction provided during the DOE course last month.I have talked to most of the participants in person and read all the course evaluations and the response was very positive. Everyone felt that the course gave them a complete understanding of the Taguchi DOE methodology and most could immediately see an application in their day-to-day work.I personally felt that you approached the subject (Taguchi DOE) in a very systematic way and therefore was easily understood. You provided excellent examples and exercises that allowed for a complete understanding of the subject. I would recommend this course to anyone who is missing this tool from their tool box."
