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.

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.

6/9/20 QI Macros Webinar

Over 140 people signed up for this webinar, with Jay Arthur demonstrating how to use some of the useful features of QI Macros, as well as some of the new features introduced in recent releases of the software.

Some attendees were familiar with the software and already use it, some had only begun to use it; all were interested in learning new ways that QI Macros can help them with their Agile Lean Six Sigma and Quality Improvement efforts. (You can hear him answering questions and comments typed in by webinar attendees.)

 



  If you saw a feature demonstrated in the webinar that might have been added to QI Macros after the version you’re using (for instance, the Templates Wizard, the Fixed Limit indicator or the automated Process Change Wizard), you may need to purchase an upgrade to bring your QI Macros to the current version.

Root Cause Analysis in the Time of COVID-19

That's root cause analysis: What are the common patterns? Where's the Pareto principle?

Tools to Monitor Your Own Health

Even before COVID-19, I gave my staff digital thermometers, oximeters and blood pressure cuffs to help them monitor their health. You can too. Here’s how:

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

“I don’t know about you but when I was a kid growing up and my mom needed to take my temperature we used something called a thermometer. This is actually the original box that it was in, but that’s no longer necessary right? Now we have these kind of tools which you can just buy at your local store. Once you press it and turn it on you just scan it across your head and it’ll read your temperature.

FOLB – Fear of Looking Bad

Humans, by nature, have a fear of looking bad (FOLB). And we have a fear of looking stupid (FOLS). These are slowing COVID-19 response and quality improvement. Here’s why:

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

“You’ve all probably all heard some of these acronyms that are running around like FOMO: Fear Of Missing Out. Well, I wanted to introduce you to a couple more that I’d like you to consider. FOLB: Fear Of Looking Bad.

“Now when I’ve gone out to work with companies in consulting roles, some of these managers think, “I’m supposed to be in charge of fixing everything.

Cholera and COVID-19 Hot Spot Detection and Quarantine

There are COVID-19 hot spots and cold spots. How do we keep the cold spots open and detect and quarantine warming spots? Maybe statistical process control can help.


 

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

“Back in the mid 1800s there was a cholera outbreak in London, and John Snow (not of Game of Thrones, but Dr. John Snow) said, “I think there’s a pattern here.” He went out and figured out that everybody who had cholera was getting water from the Broad Street pump. Back then, there was no indoor running water so you had to take your pail, go out to the pump and get your water for your home or your business or your restaurant.
