SPC - Charting and Improving Results

Everett Clinic Video, Redux – The Need for SPC Thinking

Looking at 5.x% and comparing it against an arbitrary goal does little to tell us about the health of the work system. Is 5.x% the typical average performance? Is that much higher than usual?

This is a great opportunity to use the methods of Statistical Process Control. The main management decision is to decide "react" or "not react" to that daily data point. SPC helps us with this (again, Wheeler’s brilliant little book explains this far better than I can in a blog post).

If we choose “not react” because 5.x% is lower than the goal, we might be missing an opportunity for process improvement. Generally, it’s better to present more than one data point – even if you don’t do full-blown SPC, you should present a run chart.
Well put. A simple run chart can be very helpful. One of the uses is to identify special causes. And then to use special cause thinking in those cases. What is important about special cause thinking? That you want to identify what is special about the data point (instead of focusing on all the results as you normally would). What is important about doing that? You want to do it right away (not a week or a month later). Keeping the chart lets you identify when to use special cause thinking and react quickly (to fix problems or capture good special causes to try and replicate them).

You have to be careful as we tend to examine most everything as a special cause, when most likely it is just the expected result of the system (with normal variation in the data). Special cause thinking is not an effective strategy for common cause results.

Performance and character

Response to, Toxic Employees
But what if this employee is a rock star salesperson or contributor but has the bad attitude? Do you put up with the attitude issue for the great performance?
Does performance override character?
Or do we want performance and character?
What if this person when confronted, justifies their behavior with “it’s the truth and I’m the only one with the guts to speak out”?
What if this person is a top executive with political ties to the company President yet others below feel the pain?
What if this person is not an employee but a customer?
Is it following our "respect to people principle" by not addressing this person’s behavior?

We want performance and character. It is not respecting the person (and more importantly all the others that must suffer) to ignore their toxic behavior. 

I must admit I do have sympathy for the "I'm the only one with the guts to speak out" claim. But that doesn't excuse bad behavior, speak out, but do in a non-toxic manner. 

You have to confront and address toxic behavior. It isn't easy. People with power and also people with a history to getting results can get used to being able to do whatever they want. Some cultures that is normal. 

It isn't ok in a lean culture. Bottom line. If the CEO accepts it they are deciding they don't want to be lean. They might want to adopt some lean tool (which can benefit even non-lean organizations). But allowing toxic behavior directly contradicts respect for people.

How to Motivate Front Line Workers

I see respect for people (that I think requires striving for joy in work) is critical. Dr. Deming stressed the importance of letting people take joy in work. A big part of this are many sensible respect for people notions. But also he stressed the importance of allowing people to take pride in what they do. Critical to this is providing meaningful work and organizing the work so that people can see and feel the contribution they make.

The overly simplistic example is that tightening one screw all day on an assembly line is very easy to think of yourself as a cog in a machine. Work needs to be designed to let people take pride in their contributions. An understanding of the whole system and work cells often helps. Sharing information so everyone can think of the big picture helps. Companies that truly focus on a vision can do this very well. But it is not a simple - plug this idea in exercise. To build such a culture takes an understanding of psychology and a true commitment to respect for people. Posts on my blogs about motivation.

Lean Six Sigma Health Care Sucess

Another Hospital CEO Talks Lean Culture

There’s a lot covered in the article – celebrating successes, communicating, and building on your successes. They also share a huge success in reducing waiting times for MRIs (from 25 to 28 days to just 3).

Great example. Senior leadership support and understanding is incredibly helpful. You can make progress without it. But eventually it becomes very difficult to work on the system without senior leadership support.

This example is also nice in showing that lean six sigma can work. So often organizations using the buzzwords don't have success. And it helps show different organizations can take different tactics. Many people don't like having a separate "improvement" office - as it can be seen to isolate it from everyday work. I think a separate, small, office, can help push improvement (especially in the first few years).

Monopolists Provide Lousy Service

I think there are many companies that obviously do not attempt to provide good customer service: airlines, large banks and Verizon are examples that have huge numbers of customers being treated very poorly. If there are options to choose decent service it doesn't bother me so much (credit unions provide a very good alternative to large banks most often). Thankfully you can often avoid United, American... by choosing Jet Blue or Southwest but obviously that is not always possible. Verizon is even more annoying because they have bought their way into very anti-competitive positions (banks and airlines also obviously have done so alos).

Near monopolies have the freedom to provide lousy service. Companies like Verizon, American, Chase, Wells Fargo... attempt to make their customer hostility sustainable by securing monopolistic positions. It has worked pretty well for them. I think we are much more likely to get customer friendly policies by new companies coming along that don't sell out the oligopolists. Unfortunately the anti competitive behavior these companies favor it just to buy out customer focused alternatives instead of providing service themselves.

Regulators allow such anti-competitive behavior is another thing we could hope to see change. But the chance of proper regulation of anti-competitive behavior is not good. And hoping those companies stop being so customer hostile is not something that will likely work. I don't see good odds that the monopolistic customer hostile companies will change. Those companies that don't have monopolistic positions are not such a big issue because after providing universally bad service they go out of business. It would be nice if our regulators didn't allow the monopolistic behavior but they obviously are going to do their part to allow capitalism to function, bad service and high prices is what we can expect from the monopolistic companies.
