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.

More Six Sigma Project Mistakes

If you’re not getting the results you want from Six Sigma, there might be a problem in the development of your projects.

Here are some of the mistakes I see in Six Sigma projects.

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:

Six Sigma Green Belt Project Problem

One of our QI Macros users sent me a Greenbelt Project to review. The team did a great job of using the tools and connecting the dots. There was only one small problem…

IHI 2017 Quality Tool Usage

Most of the improvement posters at this year’s Institute for Healthcare Improvement (IHI) conference are still using line, bar and pie charts, not the tools of quality improvement. There were several posters using QI Macros control charts, Pareto charts and fishbones this year from Sutter Health and Howard University Hospital.

Top Down Change Doesn’t Work

Everyone seems to think that top down, leadership-driven is the only way to implement Lean Six Sigma. It’s not.

50 years of research proves that it fails half the time. Yep, 50% failure rate. That’s less than 1 sigma.

This type of failure is so common that it even has a name: The Stalinist Paradox.

GE’s Problems – Strategy or Six Sigma?

The recent collapse of GE stock price has led to a lot of discussion. Here’s my two cents.

Jack Welch implemented Six Sigma at GE which drove many CEOs to do the same. From scuttlebutt I’ve picked up over the years, this lead to crazy rules like every employee had to do two Six Sigma projects a year. This would violate Pareto’s Rule: if  only 20% of the business is creating 80% of the defects, waste and rework, having employees try to fix the remaining 80% of the business is a waste of resources. Six Sigma needs focus, not spread.

Jeffery Immelt reduced leadership support for Six Sigma.

Signal versus Noise

“Our evolutionary instincts sometimes lead us to see patterns when there are none there. People have been doing this all the time – finding patterns in random noise.” – Tomaso Poggio

People just need a way to separate the Signal from the Noise.

Here are some insights from the book by Nate Silver.
