This was in Inc. magazine, a quote from a favorite of mine, Seth Godin (click on the graphic for a larger, easier to read view):
The scientific method is the basis of PDCA (Plan-Do-Check-Act), also known as the Deming Cycle (or the Shewhart Cycle). It’s also known as PDCA (Plan-Do-Study-Act). It’s also been re-named IDEA (Investigate, Design, Experiment, Adjust) by the design group IDEO… but I digress.
What do you think of the quote? If Lean and TPS is all about a scientific approach to problem solving, how much do you see that actually practiced in your own organization?
When you put a change in place, do you have a hypothesis about what you expect to happen? Do you disprove (or prove) the hypothesis based on observation and data?
PDCA / PDSA is intuitive to most people in healthcare… they were taught the approach (and they’ve often heard of Deming), but is it really practiced? Do you have a “culture of testing and inquiry,” regardless of your industry? Is that something you aspire to?
Thanks for reading! I’d love to hear your thoughts. Please scroll down to post a comment. Click here to receive posts via email.
