Six Sigma Formulas Cause Math Phobias

In the book, The Case Against Education: why the Education System is a Waste of Time and Money, author Bryan Caplan argues that, beyond reading, writing and basic ‘rithmatic, “most of what people learn in high school and college is unnecessary and quickly forgotten.”

I would argue that the same is true of Six Sigma; most of what people learn is unnecessary and quickly forgotten.

Peter Coy’s book review in Bloomberg BusinessWeek (January 22, 2018), states that many students struggle with algebra and drop out. City University of New York colleges are “experimenting with alternatives to conventional math because it’s a ‘killing field’ for many students,” says Chancellor James Milliken.

What are You Secretly Telling Yourself About Lean Six Sigma?

No matter what you do or what you say, there’s a hidden “metamessage” back to yourself.

What metamessages have you told yourself about Lean Six Sigma?

Reducing Patient Falls – A Case Study

The Joint Commission Journal on Quality and Patient Safety (Feb 2018) has an article entitled “Temporal Trends in Fall Rates with the Implementation of a Multifaceted Fall Prevention Program.” Ouch!

I believe the story could have been told easily with quality improvement tools, so here’s how I’d go about it. First, there are a number of tables (i.e., spreadsheets of performance data) like the one below.

jcaqo falls rates data

The first year, 2003, had only 200 falls because they started measuring in July. The first full year of measurement was 2004.

It would be easy to turn these into control charts, but the authors chose a boxplot with a trend line of predicted falls.

Hospital Costs a “Hungry Tapeworm on U.S. Economy” says Warren Buffett

I have been thinking for some time that someone would come along, start buying up hospitals and forcing them to adopt the Lean principles of Amazon and Six Sigma to achieve the “science and evidence” that Don Berwick has been challenging the IHI to adopt.

Warren Buffet has the money, but usually invests in “well-run” companies, not ones in trouble. An estimated half of all hospitals are in financial trouble (often because of the lack of Lean Six Sigma).

Bezos and Amazon have the operational efficiency needed in virtually all healthcare environments.

Dimon has a big bank.

They are all worried about the quality of healthcare and the rising costs.

Using Lean to Do Your Taxes

I started using TurboTax to do my taxes years ago. I used to gather up my 1099s and W-2 and everything else and spend a whole day doing my taxes. Your taxes may not be as complicated as mine, but think of these forms as “work in process” (WIP). I was doing them in a big batch just before the filing deadline.

Then I started using a Lean approach. Whenever a W-9 or 1099 arrives in the mailbox, I input it into the software. By mid-March when the business taxes are finished, everything is in and my taxes are ready to file.

Collapsing the Six Sigma Learning Curve

I believe we are teaching people things they don’t need to know to solve problems they don’t have to impress people they don’t like.

You don’t have to know everything about statistics to do Six Sigma projects. What you need to know adheres to the 4/50 Rule: 4% of the knowledge will deliver over 50% of the results.

And if you automate the formulas and decision trees using QI Macros, you can collapse the learning curve in such a way that “No Belts” can go from zero to hero in a matter of hours. Here’s how:
