Butt Ugly by Friday

I’ve collected a lot of sayings over the years I use during Kaizen events. Some are pretty familiar, like “Go to Gemba” or “Don’t let best get in the way of better.” But the one that seems to get the most attention and sticks with teams long after the event is: “Butt Ugly by Friday.”

Let me explain what it means and where it came from.

Kaizen events I facilitate run for a week or less, typically wrapping up on a Friday. By the end of the week, the team reports out to an audience and gets to show off the changes and improvements they’ve made. The challenge of Kaizen is: teams usually have more ideas than time. They want to improve many things, but they can easily get bogged down trying to make each one change perfect.

Years ago, I was facilitating a Kaizen in Pensacola, Florida. One of the teams was stuck on the same problem for two or three days. During a check-in with the local Lean manager, I mentioned the issue. His response changed the way I coach teams to this day.

“Adam,” he said, “you’ve got to tell them to get it Butt Ugly by Friday. That’s what we always say at the plant. It helps shift the mindset from perfection to progress. It doesn’t have to look pretty; it just has to work.”

I took his advice and helped the team move forward, even though their solution wasn’t perfect. It still made things better. Kaizen isn’t about perfection. It’s about improvement.

I use the term “Butt Ugly by Friday” in my introductory training with Kaizen teams on Day 1. It sets the tone right from the beginning. We’re not chasing perfect. We’re chasing better, safer, smarter, and faster. It gives teams permission to try things, test quickly, and learn fast. By the end of the week, team members remind me that they have improved things and made them “Butt Ugly by Friday.”

The phrase is simple, silly, memorable, and effective. People feel comfortable experimenting and are willing to fail quickly. Instead of waiting until the end of the week to find out if something works, they find out now.

Continuous improvement should be so simple and accessible that anyone can do it. More importantly, they actually want to. That’s how to build a culture where improvement can happen anytime, anywhere, from anybody.
