One Man’s Lean Journey: Process and Data Don’t Matter…Just Emotions!
Following a structured problem solving approach takes fortitude and courage when the world around you wants to shoot from the hip and judge based on their emotions. I found this out when dealing with one of the automakers we supplied.
Our quality engineer (QE) got a call that our grilles were not fitting the front of the cars correctly and asked her to take a look into it. The QE asked me to help find the root cause. We first tested our gages at our facility and found they were certified and working properly. Our parts showed to be within the tolerances given to us by the automaker.
We decided a trip to the automaker was needed to see the process, talk with the operators and also run a couple of tests. The QE and I asked the automaker’s QE to pull two vehicles off the lot and save for us to test. One vehicle is a great example of how the part should fit and one vehicle where the part fits very poorly.
When we arrived at the assembly facility the first thing the QE and I did was go out to the assembly line and talk with the operators that assemble our grilles the the vehicles. The operators said our grille may not fit the first vehicle but would work great on the next one down the line. This was a big clue. Direct observation of the process was a huge help in understanding how our grilles were assembled to the cars. We ended up knowing the process better than the automaker’s QE.
Next we asked to see the two vehicles we requested to be set aside. Well, he only saved the bad vehicle and not the good one. This became a point of contention because we needed a good car to compare the differences and conduct a test. He argued with me for 10 minutes before I finally convinced him to pull one in from the lot outside.
I conducted my test and proved with a 95% confidence level that our grille was not root cause of the fit issues. There were two possible causes: 1) the fender or 2) the fender’s interaction with our grille (the fender on one end of their specs mixed with a grille on the opposite end of our specs could cause the fit issues).
This was not received well at all. The automaker’s QE contested everything I did and wouldn’t believe the findings even though he watched me during the entire test. It took a second automaker QE to come over and see what was going on to get any agreement. The second automaker QE heard about the test and backed up my findings.
I even volunteered my help to conduct more tests to find the root cause. They agreed to the help and both the automaker and the QE from my company had action items to complete in the next two weeks in order to do further testing.
As we followed up with the automaker’s QE over the next couple of weeks, we found he was not living up to his end of the action items and was still trying to blame our grille. The QE and I had to escalate the issue to our plant manager who supported us and called their plant manager.
A compromise was reached. The test was conducted as I laid out but I was not allowed back into their facility. In the end, it was the fender that had issues.
It was hard to stick to the process when every obstacle was being thrown in the way. It taught me a valuable lesson about how strong emotions on a subject can be even with data and facts presented.
- A strong process is an amazing thing to be able to fall back on in times of stress. It showed exactly why people fall back into old habits when things aren’t going well.
- The right thing isn’t always the easy thing. It can be hard to standup for the right thing even when it is good for your customer.
- Having a leadership team that supports and encourages strong processes is critical when those processes are challenged
- Solidified my belief in the power of a strong process to get predictable and sustainable results
- Direct observation of the grille being assembled provided strong facts that no one that hasn’t seen the process could argue
