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

“Back in the 80s, I wrote a book called ‘Measuring Programmer Productivity and Software Quality,’ and strangely enough, it started to be referenced now 35 years later. I see articles; academia sends me things about it. There was a thing in there called ‘McCabe cyclomatic complexity’ which said if the number of decisions in a piece of software exceeds 10 then it starts to become unmaintainable, and when you get to about 49 or 50, it becomes completely unmaintainable and untestable.

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

“When I was at US West (the phone company), it seemed like every week, somebody would come up with some new standardized form that we had to fill out to get something done. Everybody else would bitch and moan about it, and I would just go grind my way through it, and fill it out and be done with it.

10-15 people out of 100 are misdiagnosed leading to waste, rework and patient harm. It’s a mistake to say “To Err is Human.” Blame the System, not the person. Here’s why:

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

“I was recently at the Institute for Healthcare Improvement conference, and I went to a session where they talked about diagnostic error. It turns out that 10 to 15 people out of every hundred are misdiagnosed, which means they are treated with the wrong stuff and they don’t get better and they might have other complications from the treatment.

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

“You know, a control chart is like a heart monitor… you know, it measures the performance of the heart.

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

“Have you ever gone somewhere and watched how the business works and [thought], “Why? Why do they do it that way? That’s sort of silly. Why don’t they do it a faster, better, simpler, cheaper way?” But people seem to be more attracted to spending their time continuing to fix things that are broken.

Six Sigma can go wrong. An article I read suggested at least five limitations of Six Sigma.

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

“I was reading an article that was published talking about the limitations of Six Sigma. It had a bunch, but here’s five that I thought stood out for me.

  2. The high cost of implementation.

People come up to us at improvement conferences and say: I wish I’d known about QI Macros when I was doing my Green Belt, Black Belt or DNP project. It would have saved a lot of time. It can save you time too.
