Absence blindness means that you can’t see what isn’t there. The tools of quality can help you see the invisible so that you can do something about it. Here’s how:
“Hi, I’m Jay Arthur, author of “Lean Six Sigma Demystified” and QI Macros [software].
“There’s a concept called “absence blindness,” and basically what that says is you can’t see what isn’t there. That’s why it’s kind of difficult to see things that are working well, because they just work well, but a defect or some sort of complication or issue raises this ugly head and you can see that one.

I didn’t know I couldn’t see that well until 5th grade. I didn’t know I couldn’t see how businesses worked until I learned three key tools.
“Hi, I’m Jay Arthur, author of “Lean Six Sigma Demystified” and QI Macros [software].
“I grew up in Tucson, Arizona and went to Peter E. Howell elementary, for those of you who might have gone there. I remember in classrooms from first grade on, they sorted us in alphabetical order. Well, my first [letter] is A, so I was always right in the front row. That continued all the way through second grade, third grade, fourth grade…
“And then in fifth grade they said, “No, you need to randomize how you see everybody,” so I ended up in the back of the classroom.

Someone recently asked: “What kind of data should I use for control charts and Pareto charts.” The answer is simple. Here it is:
“Hi, I’m Jay Arthur, author of “Lean Six Sigma Demystified” and QI Macros [software].
“I got a call from someone last week who was talking about how they’ve been a longtime user of QI Macros, and then how educated they were… and then they asked me, “Uh, Jay… I’m not quite sure how to set up… what kind of data should I use for a control chart, and what kind of data should I use for a Pareto chart?”

Did your quality instructors teach you to gather a team and brainstorm a problem to solve? That’s terribly bad advice. Use data to pinpoint the problem. Then, and only then do you know who should be on the root cause analysis.
I don’t know about you, but when I first got my quality training they said, “Get a team together and brainstorm a problem to solve and then go start trying to find the data, define the data, measure the data,” or something else. Now that’s the dumbest damn advice I ever got in quality training. I’ve looked at a lot of different training packages over the years and they still have all that same stupid stuff in there.

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.

People still seem to be confused about what kind of Quality Improvement chart to use. Here’s the short and simple answer:

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.

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.

People over age 55 account for 92% of COVID-19 Deaths (data from CDC). Sweden is using similar data to leave the country open for most citizens while asking seniors to stay at home. How do we reopen the economy? Self-quarantine seniors; let everyone else get back to work.
Here’s the 2019-2020 Influenza (i.e., Flu) deaths. Again, seniors are 83.5% of deaths. The flu death rate is about 1 per 1,000. COVID-19 death rate is 1-2 per 100, perhaps lower in people under the age of 55 and higher for those over age 55.
Countermeasure: Self-quarantining seniors will help flatten the curve and prevent overwhelming healthcare.

Sometimes you’ll hear people say that software isn’t necessary for Quality Improvement. Let me demonstrate how much time you’re wasting if you create ONE Pareto chart by hand, instead of using software.
“Hi, I’m Jay Arthur, author of “Lean Six Sigma Demystified” and the QI Macros [software].
“If you’ve listened to any of my Insight videos or seen me present at conferences or [had me] train you in a workshop, you know that I don’t believe you can do Quality Improvement without software. We have to stop doing Quality Improvement the 20th century manual, slow way. We have to start doing it the 21st century way, and we have to start doing it quickly.
