Kodachrome and Quality Charts

The gold standard of photography when I was growing up was Kodachrome, but you had to carefully compose your shot to get the best photos. Then you had to wait to get it developed only to discover that most of your photos were poor. Digital cameras changed all that. The same applies to Six Sigma Charts. Here’s why:

Paul Simon wrote a song about Kodachrome; when I was a kid, originally it was black and white film, but then we got Kodachrome color film that you could make really beautiful slides and everything with.

To P or Not to P

Most Six Sigma statistics rely on p values. But statisticians have been raising alarm about the problems with p values. Here’s what’s going on:



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

“I get these emails about different courses that are being offered (I think one on Coursera) but it was one on statistics and it was “To P or Not to P That is the Question.”

“Have you been watching anything in the statistics world? Statisticians think that P values can be misleading and potentially dangerous.

Old Habits are Hard to Break

I learned how to type on a manual typewriter 50 years ago. I still type the same way. Old habits are hard to break. Here’s why:



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

“Back when I was a teenager, my mother was convinced that I needed to learn how to type and so I took a summer typing course at the high school. We had those old Remington manual typewriters, right? We had to whack the key to make it fly up there and hit that ribbon hard enough that you would make a decent impression on the paper.

Software Code Quality

I’ve been building software for over 50 years. There are some secrets to software quality that are often overlooked. Here’s a few:



 

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

“I’ve spent almost my entire life working in software and software development, from mainframes to minicomputers to microcomputers, ultimately leading to the QI Macros. I’ll tell you what, I took a course a long time ago from T. Capers Jones where we studied what makes software maintainable and unmaintainable. It turns out how many decision points you have in a given module determines how testable and maintainable it can be.

Using Six Sigma to Improve Your Golf Game

People keep asking me if Six Sigma applies only to manufacturing. Nope. You can even use it to improve your golf game.

(You can download my free “Six Sigma Golf” pamphlet by clicking HERE.)



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

“I was at the American Society for Quality’s Lean Six Sigma conference down in Phoenix a few weeks ago, and one guy said, “Aren’t you the guy that wrote Six Sigma Golf?” I said “Yeah!” I [wrote] that book a long time ago. Nobody brought it up for a long time, but I said yeah; I was reading Dave Pelz’ “Putting [Bible]” and “Short Game Bible.”

Does QI Macros® Compete with Minitab?

People often ask if QI Macros is in competition with Minitab. No, I tell them. We are both in competition with a common enemy. Here’s why:



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

“I was at the American Society for Quality Lean Six Sigma conference, and my booth for QI Macros was right next to Minitab. You know, people are always asking me, “Jay, do you guys compete with Minitab?” I say, “No, we compete with ignorance and apathy.”

“Number one, people don’t know how these tools could help them, whether it’s me or Minitab.

PDCA PDSA DMAIC Whatever!

Some people use PDCA, some use PDSA, some use DMAIC. It doesn’t matter what alphabet system you use. Here’s why:



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

“When I started out (this was back in the 90s), it was Total Quality Management; the process was PDCA. Then later it was PDSA, and then it became DMAIC, and I’m sure there’s some new iteration of that that’s going to come out at some time.

“Don’t let these words freak you out: it’s just that it’s pretty much all the same process, pretty much all the same tools in the same order, right?

2/7/23 QI Macros webinar

Over 30 people signed up for this webinar, with Jay Arthur demonstrating some of the software’s most frequently used tools and answering questions asked by 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 Improvement Project Wizard or the automated Process Change Wizard), you may need to purchase an upgrade to bring your QI Macros to the current version. Send an email to support@qimacros.com and we can help, for instance in generating a quote to upgrade all the users at your organization or just guiding you through the purchasing process.

Fixing Special Causes is NOT Improvement

I have noticed that many Quality Improvement teams focus on special causes, not common causes. That’s not Quality Improvement. Here’s why:



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

“I was out working with one brewery, and they brought me into where the team was, and the team talked about all their little projects and everything else, but guess what? They were all doing special cause analysis.

“Workarounds are anti-improvement, focusing on nothing but special causes. That’s not improvement, that’s just dealing with day-to-day chaos. Improvement is when you start to reduce defects and errors, or increase patient satisfaction, or do something else.

Deming on Spec Limits vs. Variation

Deming contrasted US and Japanese focus: spec limits vs variation. Here’s the essence:



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

“I don’t know about you, but every once in a while I go back and read through books that I’ve gotten in Quality over the years. I went back into Deming’s “Out of the Crisis.” It was very interesting. There’s a thought he put in here and I’ll read it to you: “We in America have worried about specifications: meet the specification. In contrast, the Japanese are worried about uniformity, working for less and less variation around the nominal value…”

“What does he mean?
