Comparing Deming, Lean, and Six Sigma: Interview with Mustafa Shraim In Their Own Words

Andrew Stotz talks with Dr. Mustafa Shraim of Ohio University about Deming's approach to variation, comparing it to Lean and Six Sigma. "When you do Six Sigma, you're basically outsourcing your quality to an external source, providing the training, the titles, and all of that. You can cut it off any time. But when you do the [Deming] theory of knowledge and the Plan-Do-Study-Act, you have to commit. The commitment is really the big deal here...the component that is missing [from Six Sigma] is a commitment to quality."

0:00:04.1 Andrew: My name is Andrew Stotz, and I'll be your host as we continue our journey into the teachings of Dr. W. Edwards Deming. Today I'm here with featured guest, Mustafa Shraim. Mustafa, are you ready to share your Deming journey?
 
0:00:19.8 Mustafa: Absolutely, let's go for it. Thank you.
 
0:00:21.5 Andrew: I'm excited. Well, let me introduce you to the audience. Mustafa Shraim is an Assistant Professor at Ohio University teaching quality management and leadership. Professor Shraim has over 20 years of experience as a quality engineer, corporate quality manager, and consultant. His PhD is in Industrial Engineering. He publishes widely, and he has a passion for Dr. Deming's system of profound knowledge. Mustafa, why don't we start off by you telling us the story about how you first came to learn of the teachings of Dr. Deming and what hooked you in?
 
0:00:57.5 Mustafa: Yeah. Thank you, Andrew. Thank you for inviting me back. So...
 
0:01:01.9 Andrew: Yeah.

0:01:06.1 Mustafa: The whole thing started when I was doing my master's and that was the late '80s, at Ohio University, and I was concentrating on the area of quality. So, I was doing research, and my research touched up on what Dr. Deming was doing. I was doing it in design of experiments and quality tools and things like that. But of course, you come across Dr. Deming's work when you talk about quality control, in general, and statistical quality. So, that was the first encounter of learning about what Dr. Deming did in Japan and how he used statistical process control and things of that nature to teach how you can improve your processes, your products, and later on, the management. But at the beginning, I did not really get into his management philosophy so I was more on the technical end of Dr. Deming's teaching which was mainly quality control and SPC, and just improving quality in general.
 
0:02:24.1 Mustafa: So, as I went... So I went, and I started my first job as a quality engineer, and quickly after that, maybe after one year, I moved to another company, and I became a statistical quality engineer, and I was doing... I was a part of a training program there. I was doing training on SPC as a part of a training for employees at that company. It was a union shop, it was automotive, and so we utilized statistical process control and what Dr. Deming was teaching. So, that was the beginning of it, but later on in the '90s, I started learning more about Dr. Deming after I read "Out of the Crisis" and then "The New Economics" about his management method. In fact, his management methods just captured me. I knew I got hooked on the quality part first, but the management method just brought it together for me. And since then, I've been reading and practicing, trying to at least, what Dr. Deming has taught.
 
0:03:41.9 Andrew: And would you say... One of the things that I started realizing was that the statistical... What I thought was the end was the statistical tools. And what I started to learn is that, actually, the statistical tools start to have limitations i
