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.

Statistics are Simple
People have been trying to make statistics simple and easy to understand for decades.
But statistics aren’t simple. Maybe we should change how we teach them?
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.
Lean Insights from “The Founder” Movie
Early in the movie, the McDonald’s brothers describe how they came up with the concept for speedy service. It’s Lean.
They had too many menu items, so they decide to simplify down to burgers, fries and soft drinks. (Think Lean inventory.)
They go to a tennis court and use chalk to lay out a possible floor plan to deliver service fast. One brother stands on a ladder watching while the employees pantomime cooking burgers, fries and soft drinks.
They go through several iterations to converge on their final design. (Think value stream mapping and spaghetti diagramming.)
I think they might have done it faster with cardboard boxes, but I wasn’t there.
Most Valuable Career Skills
This month’s issue of Money Magazine discusses the 21 Most Valuable Career Skills. At the top of the list, statistical analysis increasing pay by 6.1%. Right behind statistical analysis is Data Mining at 5.1%. It’s incredibly easy to learn these two skills using QI Macros and Six Sigma.
Also on the list, Customer Service Metrics (4.3%). I have found that the written comments in customer service systems can be easily analyzed using the QI Macros Word Count tool to identify the most common type of call or complaint. Then simple root cause analysis can reduce or eliminate those calls.
Business analysis (3.8%) is easy with QI Macros Control Chart Dashboards.
Lean for Tax Preparation
Like a lot of people, I used to put my taxes off until the last minute. Then I’d grind away for a whole weekend getting the paperwork together and entered into my tax software. Boy that was dumb.
In the last few years I’ve started buying my tax software early and inputting every W-2 and 1099 when it comes in. When the last bit of paperwork comes in, I compare this year with last year, fix any glitches and I’m ready to file.
This is a Lean approach to handling my taxes. I handle everything, just in time, as it comes in.
Color Kanban for Hospitals
Almost every hospital storage room I’ve seen uses one color of kanban storage bin. This makes it harder to find what you want unless you know where it is. What if hospitals used colored kanban bins for the their two-bin kanban system (one in use, one for backup)? Red for blood; yellow for urinary, blue for respiratory? Wouldn’t that make it much easier to find needed supplies?

Lean – Unnecessary Processing of Online Credit Cards
Almost every time I purchase something online, I see a form that looks like this:
The Credit Card Type and Credit Card Number are redundant resulting in unnecessary duplication and processing
-
- AMEX card numbers start with a “3”
- Visa card numbers start with a “4”
- Mastercard numbers start with a “5”
- etc.
There is no reason to ask for both. The number will tell you what kind of card you’re processing. Every day, across millions of transactions, customers are asked unnecessarily for a Credit Card Type. This is a type of waste. It irritates me.

Creating a Culture of Quality
The April, 2014 Harvard Business Review has an article about creating a culture of quality. The authors found that a culture of quality will save $13,400 per employee per year. Surveyed participants also said it takes two hours to fix a mistake. Joseph Juran often said that companies lose a quarter (25%) of their revenue finding and fixing mistakes and errors, so this gives us a benchmark and a reason to embrace quality.
“Companies that take a grassroots, peer-driven approach develop a culture of quality. Traditional strategies have little effect.”
Four Factors that Drive Quality
- Leadership – As Deming said: “The aim of superision should be the help people and machines and gadgets do a better job.
How Many Green and Black Belts Do You Need?
A QI Macros customer recently asked: ” What is a reasonable and productive ratio of Lean or Six Sigma expert (LSSBB, for example) to staff for a healthcare organization that is starting the journey?”
The general consensus I can find online about Six Sigma belts/employees is:
1 BB/100 employees
3 GB/100 employeesI think these numbers are designed to keep Six Sigma training companies in business.
Depending on the size of a Medical center, you could use one BB and some GBs to get started. You can’t fix everything all at once, so one BB ramrodding a handful of GBs to solve key problems would be a good start.
