It’s Better to Beg Forgiveness than Ask Permission

In 1998, I was invited to Hoogezand, the Netherlands, to help a team make improvements to their ceiling tile production line. Little did I know it would be the longest Kaizen event in my life. I had been to the plant three months before and identified significant changeover time reduction potential. It was time to put my money where my mouth was. In advance of the trip, we identified members of the team and the need for an interpreter. I didn’t speak Dutch and still don’t. We’d have two weeks to work on the line and were to coordinate with the Production Manager any time we needed to shut the line down to work on or test the equipment.

I arrived in the Netherlands on Sunday and met with the team in a conference room on Monday morning. After introducing myself, getting to know each of the team members, and providing some Lean and changeover reduction training, we took a tour of the line to identify the highest priority areas to improve and also to get a sense for the team’s interests.

The line wasn’t running very well and I was informed this was typical. Most of the equipment was in need of repair and the maintenance department wasn’t in tune with the needs of the production organization. I told the team I wanted to meet the Maintenance Manager. They looked at me like I had asked for something outrageous. When he came out to the line, I could see why they were a bit apprehensive.

Progress vs. Paperwork

Ullrich was a very tall German man, perhaps six foot eight (I am five foot seven on a good day). With a shaved head, hands twice the size of mine, and a very low and stern voice, he introduced himself by grabbing my hand and saying, “You vill not touch or modify any equipment without filling out the proper paperwork!” Taking my hand back before it was crushed, I assured him we would follow the rules. Although he didn’t seem satisfied, he left to go to the maintenance office.

Realizing we couldn’t fill out paperwork while we were making our improvements, I promised the team I would fill out the forms at the end of each day. The team didn’t look like they believed me, but knew I didn’t want any broken fingers. There were so many problems on the line. Two weeks weren’t enough time to fix everything. With focus, dedication, and proper prioritization, I was sure we’d make significant progress.

The top priority of the team was to improve the reliability of the equalizer, which cut the ceiling boards into finished tile dimensions. Operators had a difficult time setting up the proper cutting sizes. It took hours for them to get the proper cuts. We asked the Lead Operator to shut down the line, to allow us to assess the situation and find out why it was so difficult to set up to the proper size.

Five minutes later, the Production Manager came by to find out why the line was shut down. We told him we were trying to figure out what was keeping the equalizer from being set up consistently. He reminded us we were supposed to let him know any time we were going to shut down the line. I apologized and said it wouldn’t happen again. Knowing it probably would happen again; I advised the team to remind me to let the Production Manager know our intentions before shutting the line down. They promised they would. I wasn’t so sure.

Asking the Right Questions

The equalizer used precision screws to guide the saws to their final positions on the cutting bed. Operators turned a handle to move the saws on the screws. Watching the saws move as the handle was turned, I could see the saws weren’t moving consistently. With the first full turn of the handle, it appeared the saw moved twice as far as it did with the second full turn of the handle. This situation had to be resolved. First, we had to figure out why things were acting in this way.

We tracked down a dial indicator with a magnetic base. We wanted to see how much variation was occurring when we tried to move the saws. On our first test, the handle was turned one full revolution and the saw traveled 0.020”. We turned it one full turn in the opposite direction and the traveled just 0.005”.

The team was convinced the precision screw had worn down, causing variation in movement. Thinking about this, I knew this should not be the case, but I also know what my eye had seen. Then I asked the question, “What is riding on the precision screw?” It turns out it was a brass bushing. My next question was, “Which component is more likely to wear down, the brass bushing or the hardened steel precision screw?” It had to be the brass bushing. My next question was, “When was the last time the brass bushings were replaced?” No one remembered it ever happening.

We tracked down Ullrich, explained the situation and found enough brass bushings to replace all of the assemblies on the equalizer. Four hours later, we had replaced bushings worn down to the nub with brand new brass bushings. After, we tested out changes and now had saws able to repeat their locations within 0.001”. Ullrich reminded me to fill out the proper paperwork, but was impressed enough to shake my hand. This time, he didn’t crush it.

Making Progress and Earning Trust

Over the rest of the first week, we made similar improvements to all areas of the line. We never filled out the paperwork in advance, but our earlier success at the equalizer reduced the pressure on me, the team, and my hands. We also made a game of shutting down the line and then betting on how long it would take the Production Manager to show up to see what we were doing. We were improving so many things so quickly he also gave us the leeway to shut the line down without approvals, but kept playfully reminding us to follow the rules.

The team enjoyed the work so much they decided to work on Saturday and then take Sunday off. I took Sunday to go sightseeing and got lost in the village of Makkum, 80 miles to the west, known for their ceramic tile craftsmen. That’s a story for another time.

Monday, the team was ready to make more improvements to the line. We improved almost every part of the production line by Friday morning. Our report out was scheduled for Friday afternoon. The entire plant staff showed up at the production line and listened to the team explain and show their improvements in Dutch. At the end of the report out the team said, “Adam leerde ons dat het beter is om vergeving te smeken dan om toestemming te vragen!” After much laughter and clapping by the staff, Ullrich, and Production Manager, I was told the translation was: “Adam taught us that it is better to beg forgiveness than ask permission!”
