In the practice of Lean and continuous improvement, people often describe small improvements as “Just Do Its.” Maybe they should be called “Just Do Thems” in the plural, but that's not the point of my post here.
The “Do” in “Just Do It” is what made me think. I've heard many people talk about small Kaizen improvements that are so simple as to not require root cause analysis. I agree that some improvements are so small that they don't require RCA.
My friends Jeff and Clint at KaiNexus always use an example of an employee idea about moving a trash can a few feet to the left. This idea could start with the identification of a problem, such as “People keep tripping over the trash can in the nurses' station, which creates safety risks.” Or, it's just an idea. Either way, I'm not sure that it's necessary or helpful to do root cause analysis on “Why was the trash can in a bad location?”
Hence, “just do it.” I've used that phrase before. The Cleveland Clinic uses that phrase in their outstanding process improvement work. They filter improvement opportunities into three categories:
- Just Do It
- Root Cause (some analysis required)
- A3s (a more rigorous improvement process)
You can see their red/yellow/green color coding of those through the stickers on the cards on one of their Kaizen Boards:
A vast majority of these are labeled as “Just Do Its,” which is not a surprise to me. Robinson and Schroeder have estimated that 80% of the improvement potential in an organization comes from small, staff-driven ideas (as opposed to projects and bigger initiatives). See more on “The Idea-Driven-Organization.”
And here is their breakdown of those categories at Cleveland Clinic:
I've also shared and used a diagram that's a modified version of something that was in the book The Toyota Way Fieldbook. Joe Swartz and Franciscan St. Francis Health
Those “three levels of Kaizen” are not exactly the same as the Cleveland Clinic framework (and I'm not meaning to be critical of them). Cleveland Clinic is working on small and medium improvements on their boards. The really large systemic projects are out of the scope of the local team boards, which I agree with. Those go through a different process (which could be part of Strategy Deployment management methods).
I've long said that these levels of improvement are all PDSA — Plan, Do, Study, Adjust. Some say “Plan Do Check Act” or “Plan Do Study Act.” I prefer “Plan Do Study Adjust” — but to each their own.
The A3 methodology is clearly PDCA / PDSA in its design. Strategy Deployment is arguably high-level organizational PDSA. I've also taught that small Kaizens are PDSA.
We identify a problem or an opportunity (Plan), we propose an improvement (Do), and then we evaluate if our improvement hypothesis plays out or not (Study), and we can Adjust as needed.
The Kaizen cards that I use follow that structure:
It's Plan Do Study Adjust — on a small scale (Kaizen card) or a moderate scale (an A3 improvement process).
So, upon some reflection, it seems like “Just Do It” isn't really the right phrase to use. A classic suggestion box system has cards that start with listing a suggestion. That's, in a way, jumping to solutions. Kaizen isn't a suggestion box model.
Maybe “Just PDSA It” is a more accurate phrase to use?
- Plan: We should move the garbage can to a safer spot
- Do: Move the garbage can and tell others what and why
- Study: Did it make things safer? Did the garbage can move cause any other problems?
- Adjust: Do we leave it where it is, move it back, or move it someplace else now?
That's not horribly bureaucratic to follow small scale PDSA. It doesn't require an A3. No formal project or event is needed. I'd argue that root cause analysis isn't always needed for the small stuff (again, I agree with Cleveland Clinic on this).
When I shared the first draft of this thought on LinkedIn last week, it triggered a lot of
Not everybody agreed and that's OK. I made some people think, though.

are changesso small that they don't need any formal process. If it requires more than a 30-sec conversation with the supervisor, it's not a do-it. “Do-it” is descriptive and rolls off the tongue easily.”
“PDSA might take all of 30 seconds too. Example: Trash can is in the way. Move it. Is that better? Great! Wait… No? OK, move it a little more left. Now better? Good. Thanks!”

“Great, Mark Graban. Critical thinking must be part of improvement efforts, even “minor” improvements; whether planning, doing, checking, or acting/
standardisation. Small improvements shouldn't be “no-brainers”.
I agree that “no-brainers” shouldn't mean “no thinking” or “no Study and Adjust.” What do you think?
