What Changed?

“But, this has worked, over and over for the past ten years. I am not sure why this project failed,” Jordan explained.

“First of all, the idea that originated ten years ago is not the same idea that has worked all along,” I replied. “You have modified and tweaked that idea each time there was a subtle shift in its application.”

Jordan was complaining. In this case, at this time, he would rather complain than consider a new idea he didn’t like.

“Each time you tweaked the idea,” I continued, “the shift was so subtle that you hardly noticed. And, your idea worked until it didn’t. Something has changed. Something has changed internally, externally or both. What was it?”

When Did This Start?

Marvin was not in his office when I arrived. It didn’t take long to find him among a group of people desperately trying to solve a problem with a machine on the floor.

“It’s always something,” Marvin said. “Just when we get one problem solved, it seems like something else goes out of whack. We are trying to figure out why this thing won’t maintain the pressures we need.”

“When did all this start?”

“Weird, it started just a couple of months ago. We have been making these units this way for ten years. We have tweaked almost every parameter and this guitar is so out of tune, it sounds sick.”

“So, what are the factory defaults on the unit? What are the baselines?” I asked. Marvin just stood there. You could see the blood draining from his face.

“Well?” I said.

Marvin shook his head. “You are suggesting we clear the decks and go back to square one?”

Twenty minutes later, after restoring the defaults and making three adjustments, the machine was holding tolerance. For the first time in two months.

Often, we try to solve the wrong problem.

The Underlying Problem

Leave a reply

Often, the problem we seek to solve is only a symptom of something underneath. We examine the symptom to identify its root cause. And, sometimes, even root cause analysis fails us.

Sometimes, the root cause does not lie in the problem, but in the way we see the problem. The way we talk about a problem is a function of what we believe, our assumptions about the problem.

Does the way we state a problem have an impact on the way we approach the solution?

What we say is what we believe.

Before we grapple with the problem, it is important to understand our beliefs and assumptions about the problem. It could be the problem is not the problem. The problem could be what we believe about the problem that is simply not true.

Get to the Root Cause of the Problem

Emily was nervous as she entered the classroom. She knew that I would not allow her to be a passive observer, but front and center in the crucible. I turned to greet the other folks who were now streaming in.

“I would like everyone to meet Emily. She has an interesting problem at work. With our help, she is going to walk us through some solutions.” Emily looked at me sideways. It would take her a bit to trust this group.

Up at the front, Emily stood. “I really don’t know what kind of problem I have,” she started. “Our manufacturing line is not meeting its daily quota and the reject rate is at 11 percent.” Emily continued to describe the circumstances, considering morale, motivation and working conditions. Then the questions started from the group.

“Who decides the daily quota?”
“How is the daily target communicated to the line?”
“Who tracks the number of completed units?”
“How does the line know if they are falling short or getting ahead of the target?”

Emily responded crisply, “The daily quota is determined by the sales forecast and what we need in stock, but the people on the line don’t need to know that. They just need to build the units faster. When the QC people pick up the units for inspection at the end of the day, they count them and it’s on my report the next day.”

Ernesto raised his hand. “So, the line doesn’t know how far they missed Tuesday’s quota until Wednesday?”

“Not exactly,” Emily replied. “I don’t want to discourage them, so I just tell them they were a little short, that they are doing good job and to try harder. I am worried about morale getting any lower.”

Ernesto tilted his head to directly engage Emily. “You are treating this issue as a morale problem. Morale is only a symptom. You have to treat the root cause of the problem, not the symptom.”

Randy dragged a chair up front for Emily to sit. We were going to be there a while.
