Here is the recording:
My favorite book, as I've written about before, is not a “Lean book” — it's Understanding Variation: The Key to Managing Chaos by Donald J. Wheeler, PhD.
It might look like a book about statistics (and it has an esoteric sounding title), but I'd call it a management book, and a very practical and useful one at that.
See my post from 2013:
I'm excited that Don Wheeler is going to be one of the keynote speakers at this year's Society for Health Systems Healthcare Systems Process Improvement Conference this March in Orlando. I hope to see you there! I'll be talking about the conference a bit in tomorrow's podcast with Isaac Mitchell.
You can read an interview with him here. In part…
“What is the most pervasive issue or challenge in health systems management today?
Among the many challenges for healthcare management is the challenge of using data more effectively. We are told to be more data-driven, yet no one provides any effective mechanism for doing so. Big data techniques require extreme sophistication on the part of the user to avoid being misled by noise.”
Why do I think this is such an important topic?
Update: I wrote a book on this topic:
I see a lot of organizations practicing some form of what they'd describe as “Lean Daily Management” or something like that.
There are a lot of good practices that I see, including:
- Continuous improvement or Kaizen boards (although sometimes, these get overcomplicated)
- Daily team huddles (although these sometimes don't have much energy or team participation)
- Rounding or “gemba walks” (although these are sometimes more ceremonial than helpful) and
- Daily performance metrics and charts
It's generally good to see daily performance measures. It's certainly better than monthly metrics that lag two months behind.
Real-time daily metrics are much more helpful for understanding our system, driving improvement, and reacting to changes in the metrics (good or bad).
But, the way these metrics are done sometimes causes problems… or it's just not an ideal way to do things.
In my experience, the approach of Lean Daily Management (and performance tracking) works better when we:
- Use “line charts” for time series data instead of what Excel calls “column charts” (often called “bar graphs”). This is a relatively minor point in that changes and trends in bar charts are visually harder to interpret than lines.
- Avoid using statistically dubious “linear trend lines” that can be misleading (often unintentionally so, but you're never quite sure). Wheeler would say that a chart should never lead to somebody drawing the wrong conclusion about whether something is improving (or not) or stable.
- Avoid arbitrary goals or targets for improvement, which can be demoralizing if management is asking the wrong questions, such as “what went wrong yesterday?” instead of asking “how can we improve our system and its performance, in general?”
The methods that Wheeler writes about (and that I've used and taught) aren't complicated.
But, these methods help managers and teams make better management decisions. That leads to more improvement, better performance, and less frustration.
Managers and teams need to be able to answer important questions, such as:
- Do we have a stable system with stable performance?
- Can we predict tomorrow's performance?
- How do we know if there's a data point that's worth investigating (one that's good or bad in statistically significant way)?
- How can we distinguish “signal” from “noise” in our charts and metrics?
- How do we know if a process improvement effort has led to meaningfully and sustainably better performance?
- If our current performance isn't meeting our goals, how can we improve the system? And how do we know if we've made a difference?
I've written other blog posts that draw on the lessons from Understanding Variation, including:
Upcoming 2017 Workshops
Here in 2017, I'm going to be teaching some workshops about these themes and practical lessons from the Deming “Red Bead Experiment.” See my previous webinar about that with Mike Stoecklein:
Info about those workshops:
One time I'm running this, we're using the title: “Understanding Variation and Performance Management: Practical Applications of Dr. Deming's Red Bead Experiment”
- Lean Healthcare Transformation Summit (Brussels – March)
And we're also experimenting with what we think might be a better title (same workshop, continuously improved) under this title:
“Better Metrics: Understanding Variation and Managing Performance Using Deming Methods”
And, again, check out my free webinar: “How to Manage Your Improvement Metrics More Efficiently and Effectively.”
