Are You Sewing Your Own Six Sigma Toolkit?

Mom used to sew all of her own clothes, just like many people in Six Sigma are creating their own chart templates or code. Mom figured out a better way. You can too.



“Growing up in the 50s, my mom made all of her own clothes. She would go to the fabric store and pick out fabrics and pick out patterns. She’d come home and on this big cardboard thing she’d lay out the pattern on the thing and cut out all the pieces. Then she’d have bought thread, and then she’d sit there at the sewing machine and she would sew blouses and skirts and dresses.

Arthur’s 4-50 Rule – The Secret to Breakthrough Improvement

We’re all familiar with Pareto’s rule: 20% of causes produce 80% of the results. But are you familiar with Arthur’s 4-50 rule? Typically, 4% of any process – one step out of 35 – is the cause of more than 50% of waste, rework and lost profit.



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

“Now I’ve probably talked to you about this before, but we’re all familiar with Pareto’s rule that 20% of what you do produces 80% of the mistakes, errors, waste, rework, lost profit. 20% of your customers produce 80% of your revenue.

2021 New Year’s Resolutions for Quality

Here’s three New Year’s Resolutions to accelerate your quality improvements: 1) Raw Data Diet, 2) Quality Tools and 3) Worst First. Here’s why these will change your future and your company’s:



“Hi, I’m Jay Arthur. It is the New Year and so it’s time for some New Year’s resolutions. Here’s some resolutions I’d like you to consider.

“First, go on a raw data diet. That means you need to know everything about each individual defect, mistake and error, and then you can summarize that. If you start from summarized data you don’t know where the raw data is, and so most of the time you can’t actually figure out what to fix without the raw data.

Six Sigma Dogma

When I started in quality improvement, everyone preached Total Quality Management (TQM). Before that it was quality circles. I’d like you to consider that the gospel of Six Sigma is holding back progress. Here’s why:



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

“The other day I was [presenting] a webinar for one of the ASQ sections; I’ve been doing Agile Lean Six Sigma webinars for the Agile sections that want something to do during this pandemic. One of the guys said, “Well, you’re sort of telling me that that we don’t need Green Belts and Black Belts to do a project.

Lean Vaccine Development

Vaccine development companies aren’t taking shortcuts; they are using Lean to accelerate delivery of a safe effective vaccine. Here’s how:



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

“There’s been a lot of anxiety about vaccine development, like, “Oh, they’re short-cutting.” Uh, no. No, okay.

“If you know anything about Lean, you know that the original process was they did phase one trials. Then they evaluated the phase one trial and then they set up a phase two trial. So the phase two trial [is going] and and then they would evaluate all of that and then they would say, “Well, was that okay?”

Embrace the Automatic Transmission

I learned to drive on a stick shift. Then automatic transmissions came along. What have you learned the hard way that has been simplified and automated? How much time and suffering could you save by embracing the automatic transmissions available in Quality Improvement?



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

“Now way back in the 60s when I was learning to drive (yes, I’m that old) they had the student [car], but it had a “three on the column” manual shift – an old Chevy Caprice or something like that.

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.
