In my travels, I often meet people or visit organizations that say something like:
“We're doing Lean… we just call it Process Improvement.”
They have a “Process Improvement” (PI) department, or they call it “Continuous Process Improvement” (CPI). They have people in roles like “Process Improvement Facilitators.”
While process improvement is great, in using a term like that, there's perhaps a risk that they miss the full and complete essence of Lean and, therefore, don't get the results that they might hope for.
“Lean” is based on the Toyota Production System and The Toyota Way management approach. Those who coined the term “Lean” had to come up with a descriptor that wasn't completely based on Toyota for these methods to be more accepted in the rest of the auto industry and in other settings. Toyota's own website says that Lean is basically a synonym for their approach.
Toyota (and their TSSC organization) can say they are teaching “TPS” to other organizations, but most others call it Lean. I'm not a Toyota guy, so I wouldn't feel right using the Toyota name or label for my work, as some others do.
I understand how the term “process improvement” might be less threatening than the word “lean,” with all the negative connotations that can come with it. Lean often makes people think of layoffs or not having what we need to do our work, although the Lean methodology is actually a great alternative to layoffs and a Lean environment provides better systems that provide what is needed for people to do work the right way.
Using the term “process improvement” sells Lean short. Yes, Lean provides methods and frameworks for identifying and eliminating waste and providing better value to customers. Lean tools and projects can be utilized to drive measurable improvements in a short period.
Lean is more than process improvement. It's more than engaging front line staff in continuous improvement. As Jamie Bonini, the leader of Toyota's TSSC organization that works with suppliers and non-profit organizations, explains, TPS (and Lean) is, at its foundation, an “organizational philosophy.”
Toyota describes TPS as an “integrated system” that includes:
- Technical methods (like just-in-time practices and “jidoka” to build in quality at the source)
- Managerial approaches (inspiring and developing people through problem solving)
That philosophy is, according to Bonini:
- Customer first; provide customers with what they want, when they want it, and in the amount they want it
- People are the most valuable resource; Deeply respect, engage, and develop people
- Continuous improvement (kaizen); Engage everyone each and every day
- Shop floor (gemba) focus: Go to where the work is done to find and solve problems
See this page from Toyota's website with a helpful diagram and more details about this approach.

Process improvement is a good thing, but Lean should be more than that.
Can a “Process Improvement” team influence the way managers operate?
Can a PI team influence senior leaders to embrace new mindsets and approaches to leadership? Far too often, they cannot. Senior leaders too often think “implementing Lean” is a matter of training frontline staff and managers. These senior leaders far too often don't ask their PI team (or outside consultants, like myself) to help them change. They often define the problem as “bad processes,” not “bad leadership.”
Using the technical methods of TPS, sometimes referred to as “Lean tools,” outside of a Lean culture, runs the risk of being ineffective or counterproductive.
The right tool in the wrong culture can cause a lot of frustration, as I've blogged about before, whether that's a Ford plant where people got in trouble for pulling the “andon cord” or my GM plant where people got yelled and screamed at about their hourly production numbers:
Lean should be a management system and a culture… at least it should be if an organization is trying to be as great as they can be.
In addition to “process improvement,” Lean should also be about designing new processes and workspaces (or reinventing them) in a “Lean Design” way. See posts and podcasts about this:
Does the focus on (or the label of) “process improvement” diminish Lean and hold back the progress that could be made out there? Is process improvement a good start as long as an organization aims to eventually accomplish more on the culture change front?
