DevOps and QualOps

At ASQ LSS Conference in Phoenix, I heard an interesting presentation on digital transformation. Ben Lavoie of Anheuser-Busch asked:

How can LSS Stay relevant in a Digitally Transformed world that thrives on real-time changes?

Bad news: Need for real-time will disrupt DMAIC – leadership teams have no patience for delayed analysis and decision making

Good news: Still need people

Great news: Digital tools need LSS to solve the right problems

 

I think this speaks to the need for Agile Lean Six Sigma.

Ben also mentioned DevOps, how companies are integrating IT with operations in a continuous feedback loop:

I think if we substitute PDCA for the left loop and link it to operations feedback, we can get the same real-time results with Six Sigma.

Testimonial from ASQ Phoenix

At the ASQ Conference in Phoenix, and got some wonderful comments from one of the attendees who uses QI Macros:

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.

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.

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.

Focus of Lean Six Sigma Projects

At the Shingo Conference in Atlanta this week, Professor George Easton presented findings from a study of two company’s Six Sigma projects. He split them in many ways, but the simplest view uses operations management metrics: quality, cost, delivery, flexibility and innovation. Here are Pareto charts of the two companies. Both focus on quality, but one is more focused on delivery; the other is more focused on innovation and cost. Professor Easton suggests that this might indicate a difference in strategy.

What do your Lean Six Sigma projects say about your corporate strategy?

Correlation not Causation

As John Johnson and Mike Gluck point out in their book, EVERYDATA, ice cream consumption and murder rates both go up in the summer, but that does not mean that eating ice cream causes murder. Rising summer temperatures seem to be involved.

They also provide a link to Tyler Vigen’s website, Spurious Correlations.

Does U.S. spending on space, science and technology cause suicides? No, but they are correlated at a 99.79%. These and other crazy correlations are available.

So don’t confuse correlation with causation.

Hassle Week 5/7/16

This week CenturyLink cancelled our voicemail seemingly at random. Had to call to have it restored. My problem: unnecessary rework; time 30 minutes. Root cause? unknown.

There was a 25% off coupon in my mailbox for my local Ace Hardware. But when I went to check out, the system wouldn’t accept my coupon. I had retrieve the flyer to prove the coupon was valid. Problem: rework, time 30 minutes plus driving. Root cause: Marketing not in sync with sales systems.
