Swami from Maintenance / Occam's Razor principle

The "occam's razor" principle dictates that the simplest explanation is usually the best one.

A toothpaste factory had a problem. They sometimes shipped empty boxes without the tube inside.

This situation challenged their perceived quality with the buyers and distributors. Understanding how important the relationship with them was, the CEO of the company assembled his top people.

They decided to hire an external engineering company to solve their empty boxes problem. The project followed the usual process: budget and project sponsor allocated, RFP, and third-parties selected.

Six months (and INR 8 crores) later they had a fantastic solution – on time, on budget, and high quality. Everyone in the project was pleased. They solved the problem by using a high-tech precision scale that would sound a bell and flash lights whenever a toothpaste box weighed less than it should. The line would stop, someone would walk over, remove the defective box, and then press another button to re-start the line.

As a result of the new package monitoring process, no empty boxes were being shipped out of the factory. With no more customer complaints, the CEO felt the 8 Crores was well spent.

He then reviewed the line statistics report and discovered the number of empty boxes picked up by the scale in the first week was consistent with projections. However, the next three weeks were zero!

The estimated rate should have been at least a dozen boxes a day. He had the engineers check the equipment, they verified the report as accurate.

Puzzled, the CEO traveled down to the factory, viewed the part of the line where the precision scale was installed, and observed, just ahead of the new 8 Crores solution, a INR 600 desk fan blowing the empty boxes off the belt and into a bin. He asked the line supervisor what that was about.

“Oh, that,” the supervisor replied, “Swami, the kid from maintenance, put it there because he was tired of walking over every time the bell rang!”
