Using Theory of Constraints to Accelerate Lean Six Sigma

Theory of Constraints (TOC) can give us insights into how to accelerate Lean Six Sigma and get results in a day. Here’s how:



“Hi, I’m Jay Arthur, author of “Lean Six Sigma Demystified” and QI Macros [software].

“You know, I’ve been around Quality for almost 30 years now; 30 years exactly, almost. If I think about it, it’s super cool… but why is it so slow and so unsticky? Why is it taking so long for it to get everywhere? I’ve come up with some theories about that.

“If you’re familiar with a technique called “Theory of Constraints,” there’s a whole process to figure out why things aren’t running as quickly as they should.

Accelerating Software Quality Using the 4-50 Rule

Leaders, managers and programmers sometimes get frustrated with software systems and try to rewrite them. This usually fails. It is possible to use Six Sigma and the 4-50 rule to find and fix the few code modules that have the most bugs and require the most enhancements. This delivers software quality without the high cost and risk. Here’s how:



“Hi, I’m Jay Arthur, author of “Lean Six Sigma Demystified” and the QI Macros [software].

“Today I want to talk to you about software. Now, some of you may work in software, some of you may use software… (If you have a phone, you’re using software) There’s lots of software around, and sometimes there’s bugs and stuff like that, and sometimes we’re enhancing things.

Cut The Cockleburs for Hassle-Free Living

Six Sigma isn’t just for business. You can use it to make your life more hassle-free. Here’s how:  Become the CIO of Your Life. 



“Hi, I’m Jay Arthur, author of “Lean Six Sigma Demystified” and the QI Macros [software].

“I used to walk my dog Coco on the High Line Canal that runs for about 73 miles throughout Denver. I’d take her for a walk and she’d go running around, but she’d pick up these cockleburs. A cocklebur plant stands about waist-high, has big broad leaves and it produces these little spiny things about the size of the top of my thumb that has little hooky things all around it.

Yankee Spirit Goal Setting

Yankee Spirit (50% reduction in delay, defects and deviation) is easy to achieve. It’s imperative. Here’s why:

“Hi, I’m Jay Arthur, author of “Lean Six Sigma for Hospitals” and QI Macros [software].

“When I first got started in Quality Improvement, our training folks talked about Yankee Spirit as a method of setting a goal. What’s Yankee Spirit? Well, Yankee Spirit is simply a 50% reduction in delay, defects and deviation.

“Well, that just sounds like we’re just taking a dartboard throwing a thing at it, but it was years later that I realized that this is actually scientifically doable. As I started to look at it, Pareto’s rule says 20% of what you do produces 80% of the waste, rework, lost profit, patient harm… whatever you want to call it.

Trends Are Not Always Improvements

Line charts with trend lines can be misleading. They can provide a kind of “false positive” that implies improvement where there is none. Here’s why:

“Hi, I’m Jay Arthur, author of “Agile Process Innovation.”

“I go to all these trade shows and I see a lot of poster presentations but they’re using line charts and then they draw a trend line through them and then they say, “Oh, we made an improvement.” No you didn’t. If it doesn’t really fit the line very well, if your goodness-of-fit metric is less than 80%, I’m not buying it. But nobody gives me a goodness-of-fit metric called r-squared, they just show me a line graph or a bar chart and then they show a little line through it.

Mammograms are a Type of Inspection

Breast Cancer is Rare, yet we subject women to mammograms to try to detect it. False positives are 20X higher than true positives. Deming said: “Cease dependence on inspection to achieve quality.”



“Hi, I’m Jay Arthur, author of “Lean Six Sigma Demystified,” “Lean Six Sigma for Hospitals,” and the QI Macros [software].

“I found another interesting item in Malcolm Gladwell’s book; again, it was in the back notes. They were talking about mammograms. Breast cancer itself is really rare, it’s like less than a half of 1% of women who get a mammogram actually have cancer, so it’s like looking for a needle in a haystack.

Why Are People Using Line and Bar Charts, not Control Charts?

If you look at improvement project posters at quality conferences around the country, you’ll find that almost everyone is using Excel line and bar charts. Even after decades of Six Sigma training and association membership. What’s the hold up? Here’s my take:

“Hi, I’m Jay Arthur, author of “Lean Six Sigma Demystified” and QI Macros [software].

“Every year I look at lots of improvement posters and I keep wondering, “Why isn’t anyone using the tools of Quality?” Control charts, Pareto charts, histograms… Most of them are just using plain old Excel line and bar charts. Now it might be because they don’t know about the power and beauty and how easy it can be now to do Control charts, Pareto charts and fishbones.

Predators are Lazy

Predators are lazy. So are humans. Here’s why that’s a problem:

“I was out in Hawaii and I saw these people doing shore fishing. I thought, “That might look fun.” I went to this one store that sells sporting goods stuff and I said, “Is there anybody who has a class or anything on shore fishing?” He said, “No, no; nobody does that,” he said. “But all you have to understand is that predators are lazy.”

“I think I’ve talked about this before, but essentially, the predatory fish come in on the tide and then they go out on the tide.

Is It Time to Rethink and Simplify Quality Improvement?

At the ASQ Lean Six Sigma Conference in Phoenix, keynoter Gregory Watson asked: “Is it time to rethink and simplify quality improvement?” I believe Agile is the answer:



 

“I was out at the ASQ Lean Six Sigma conference in Phoenix [earlier this year]. Dr. Gregory Watson, the keynote [speaker], was also the keynote [speaker] at the very first conference back in 2000. He said, “Is it time to start to rethink what we’re doing in Quality? Can we simplify what we’re doing?”

“I say the answer to that question is yes, obviously, because I’ve been talking about Agile Lean Six Sigma: How do we take the skills of Agile and apply them to Lean and Six Sigma so we can get results in a day or two; not in weeks and months and years.
