A toothpaste factory had a problem: they sometimes shipped empty boxes, without the tube inside.

What has a picture of a cute blonde brushing her teeth got to do with this story? Answer, nothing at all. You try finding an interesting picture of a toothpaste production line on Google. Go on, I dare you.
This was because of the way the production line was set up, and people with experience in designing production lines will tell you how difficultit is to have everything happen with timings so precise that every single unit coming out of it is perfect 100% of the time.
Small variations in the environment (which can’t be controlled in a cost-effective fashion) mean you must have quality assurance checks smartly distributed across the line so that customers all the way down the supermarket don’t get pissed off and buy someone else’s product instead.
So, understanding how important that was, the CEO of the toothpaste factory got the top people in the company together and they decided to start a new project, in which they would hire an external engineering company to solve their empty boxes problem, as their engineering department was already too stretched to take on any extra effort.
The project followed the usual process: budget and project sponsor allocated, RFP, third-parties selected, and six months (and $8 million) later they had a fantastic solution — delivered on time, on budget, high quality and everyone in the project had a great time.
They solved the problem by using some high-tech precision scales that would sound a bell and flash lights whenever a toothpaste box weighing less than it should came down the line.
The line would stop, and someone had to walk over and yank the defective box out of it, pressing another button when done.
All well and good. So … a while later … the CEO decides to have a look at the ROI of the project: and yes, they were amazing results!
No empty boxes ever shipped out of the factory after the scales were put in place. There were very few customer complaints, and they were gaining market share. “That’s some money well spent!” – he says, before looking closely at the other statistics in the report.
And that’s when it hit him. It turns out, the number of defects picked up by the scales was precisely zero after three weeks of production use.
But it should’ve been picking up at least a dozen a day, so maybe there was something wrong with the report?
He filed a bug against it, and after some investigation, the engineers come back saying the report was actually correct. The scales really weren’t picking up any defects, because all boxes that got to that point in the conveyor belt were good.
Puzzled, the CEO drifts down to the factory, and walks up to the part of the line where the precision scales were installed.
A few feet before it, there was a $20 desk fan, blowing any empty boxes that came down the belt off the line and into a bin.
“Oh, that? One of the guys put it there ’cause he was tired of walking over every time the bell rang”, says one of the workers.
So let’s just run that by you again.
Cost: Six months and $8,000,000 on Consultants and equipment.
$20 on a Fan
Total: $8,000,020
What are the three crucial lessons from this story?
CEOs need to get out of their ivory tower – all senior management does – and engage in a little Management by Wandering Around. It is very rarely wasted time. In my experience, having advised hundreds of organisations for more than 20 years, the companies where the CEO and Directors are most familiar with the day-to-day affairs of their businesses are those that are both successfully reactive and intelligently pro-active, and enjoy happy and productive work relations.
Second: if you’re the boss, trust your workers’ commonsense, (they actually do the work, after all), ask their advice, and listen to the answers. It might just save you eight million bucks.
Third: if you’re a smart worker and your company doesn’t listen to what you know, then get the hell out and go and work for someone who does.
