General FAQ's

How do we learn Design of Experiments (DoE)?
ObDOE offers practical DoE training in plain English.

Training at your facility

Why should you choose Objective DoE training?
This is why!

See what our students say.


What is the Return on Investment on Design of Experiments (DoE) training?
To determine your specific Return On Investment (ROI), please use our worksheet.

In general, if you train 10 people with our uniquely practical DoE method, and assume only
one person doubles his/her efficiency, the training costs for all 10 people will be recouped
in one year.

In this article Lexmark International quoted an ROI of 70% from ObDOE training!


How much faster is Design of Experiments (DoE)?
For a typical 5 factor experiment, 1/3 of the time you would need using the old method!

This is estimate is from "Statistics for Experimenters," by Box, Hunter, and Hunter, p. 313


Tell me more about the "map".
The computer organizes the results of your designed experiments in several ways.

The "map" provides a picture of your data, much like a topographical map is a "picture"
of a certain area of land. You follow the lines of the map to see what
would be the results of an experiment you didn't actually run.

For example, let's say you run experiments at 250 and 350 degrees, and get results of
"10" and "24", respectively. Your map will show you what number you might expect at
325 degrees, even though you didn't actually run that experiment or measure that result!


Is the map related to Response Surface Methodolgy (RSM)?
Yes. The "map" is a map of your "Response Surface."
