(Optional Third-day): Experiment Design Workshop
The participants will work together under the instructor’s guidance to analyze a product or process design issue in your organization.

Course Overview

Course in a Nutshell

This course brings together important concepts that give your technical staff the capability to optimize product designs and manufacturing processes using advanced design of experiments technologies.
We will briefly review basic statistical concepts and then move on to more advanced design of experiments concepts. The course provides an organized approach for systematically and quantitatively defining key performance parameters in both the product design and the manufacturing process. The course utilizes real-life case studies that help your staff apply this toolkit. At the end of the course, your staff will know how to identify key performance parameters and determine appropriate control limits through appropriately-focused design-of-experiments tests.


Customize It!

Whatever the nature of your system and your objectives, we will customize the course to meet your specific needs and concerns. Here are some of the ways in which we can tailor the course to help you get more out of it:

  • Add a “workshop day” (third day) to the course to allow the participants to work together to analyze a product or process design issue in your organization. The workshop day can be scheduled a few weeks after the course to allow time for applying the technologies presented in class under an experienced design of experiments practitioner’s guidance.
  • Schedule post-class follow-up consultation for continuing in-house product and process optimization challenges.


Learn How To

  • Work together in an effective team environment to resolve product and process optimization challenges.
  • Use design of experiments technologies to identify key product design and process tolerances and control limits.
  • Reduce or eliminate areas of specification non-compliance.
  • Reduce or eliminate scrap and rework causes.
  • Proactively eliminate potential product and process shortfalls before they occur.
Audience / Prerequisites

Aimed At
