Design of Experiments Course

A little background and motivation for the material in this course.

  • Welcome
  • Instructor Introduction / Background
  • Course Format / Materiasl / Software


The material was very clearly articulated.  Allise is very knowledgeable about the subject as well as very excited about it.  She does a good job explaining the topics and putting them into real-world applications.

Training Objectives

The objective of Design of Experiments Training is to provide participants with the analytical tools and methods necessary to:

  • Plan and conduct experiments in an effective and efficient manner
  • Identify and interpret significant factor effects and 2-factor interactions
  • Develop predictive models to explain process/product behavior
  • Check models for validity
  • Apply very efficient fractional factorial designs in screening experiments
  • Handle variable, proportion, and variance responses
  • Avoid common misapplications of DOE in practice

Participants gain a solid understanding of important concepts and methods to develop predictive models that allow the optimization of product designs or manufacturing processes. Many practical examples are presented to illustrate the application of technical concepts. Minitab or other statistical software is utilized in the class.

Why is DOE Training Important?

Experimentation is frequently performed using trial and error approaches which are extremely inefficient and rarely lead to optimal solutions.  Furthermore, when it’s desired to understand the effect of multiple variables on an outcome (response), “one-factor-at-a-time” trials are often performed.  Not only is this approach inefficient, it inhibits the ability to understand and model how multiple variables interact to jointly affect a response.  Statistically based Design of Experiments provides a methodology for optimally developing process understanding via experimentation.

In this course, participants gain a solid understanding of important concepts and methods in statistically based experimentation.  Successful experiments allow the development of predictive models for the optimization of product designs or manufacturing processes.  Several practical examples and case studies are presented to illustrate the application of technical concepts.  This course will prepare you to design and conduct effective experiments.  You will also learn how to analyze the data from experiments to understand significant effects and develop predictive models utilized to optimize process behavior.

Without question, this class was the most beneficial training I have received for my particular job function.  I will be able to utilize the information on the job immediately.
