Don’t Fix the Defect

“But, it’s like pulling teeth to get them to change the way they have been working. They get started, but after a couple of days, things are right back to the way they were before.” Matt sighed one of those Manager’s sighs. “I just wish my team was more disciplined.”

“Matt, discipline is nothing more than routine. Discipline isn’t harder than any other way of getting things done; it’s just not what you are used to.”

I spied a workroom on my way in. It was a small room with some simple tools and a work bench, good lighting. It was where people took things that needed fixing. Not broken things, but rather, product defects. The seam on the unit didn’t line up quite right; there was a burr on an edge. Rather than documenting the defect and looking for a solution, the team had, over time, assembled this little “fixing” room.

“Tell you what, Matt. Hide the tools and put a padlock on the room.” I could see his eyes grow wide. “Then, have a meeting and tell everyone that the fixing room is off-limits for 21 days. During that time, have meetings twice a week to talk about the new defect-documentation process. After 21 working days, you should have a new routine. Discipline is just a different way of getting things done.”

Matt was nodding, “So, after 21 days I can take the padlock off the fixing room?”

“No.”

Pulling Bad Product

“We have a problem with consistency,” Donna said. “I think everything is going okay and then boom, we get hit with a warranty event that uncovers a whole batch of bad product. I have two people doing random inspections prior to shipping. Still, mistakes get through. I might have to add more inspectors, check everything, just to keep bad product off the shelves.”

“What do you do with the bad product?” I asked.

“Well, we can’t sell it and we can’t melt it down, so we throw it away,” replied Donna.

“Do you use bad product to isolate the problem production area?”

“Oh, we know the three areas where we have problems, but rather than pull bad product in three places, I thought it best to inspect just before shipping, so we can pull all the bad product at the same time, no matter where the problem occurred.”

I winced. “Donna, is the purpose of Quality Control to pull bad product, or to identify the problem and fix it? Consistency doesn’t come from pulling 3 percent of your production. Consistency comes from fixing your system.”

Your Customer is Not Your QC Department

“You cut your lead time from six weeks to four weeks. Higher throughput with the same number of people, with the same equipment, in the same facility, you lowered your cost. You shifted from just getting the orders out the door, to a consistent, predictable system. And that’s when your troubles began?” I was curious.

“Yes, we were certainly focused on our systems,” Arianne continued, “but we had to match a competitors warranty. We figured, no problem, but we were wrong. We had our cost-to-produce down, but our warranty returns went through the roof. Everything we made up in cost savings went right back out the door in warranty repairs and replacement. We had a quality problem.”

“Pace and quality,” I said softly.

“Yes, our throughput was quicker, but it just meant we were making mistakes faster.”

“What did you do?”

“We were relying on our customer to be our Quality Control department. Bad move. We had to retrench, put inspections after each major step, so if we had a problem, we could identify it before we made another thousand parts. We tracked everything on white-boards. We didn’t make it to six-sigma, but enough quality improvement to make a big difference.”

“So, finally you got organized, accelerated your throughput, beat your internal quality standards. It must have been a proud moment,” I encouraged.

“Not really,” Arianne replied. “That’s when the rug got pulled out from under.”
