“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 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.

Seems like everywhere I shop, employees are more comfortable fixing stuff than fixing the process. Does this sound familiar?

“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.

“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.
- High failure rate. That’s right. A lot of these implementations don’t work, and it puts a bad color on Six Sigma.
- The high cost of implementation.
