Utilization as a productivity measuring number
Utilization is a single number that is a measure of your machine’s efficiency.
It is a great measure if you have a mass production situation – the same part is running continuously, and there are no part changes.
Based on the part’s standard cycle time, you know how many parts must be produced in a given time. This is the Planned production quantity.
Utilization = No. of good parts produced / Planned production quantity
E.g., You have 7.5 hours in a shift, and the standard time to produce a part is 30 minutes (cycle time + unload and load time). The planned production quantity is 15 parts per shift. If you produce 14 parts, Utilization = 14 / 15 = 93 %.
When you analyze this formula for Utilization and the one for OEE, you’ll realize that they are the same. The difference is that in OEE you split up the productivity into 3 components A, P and Q – how much the machine ran in the time that was available, how efficiently it worked in the time that it ran, and how many good parts it produced compared to the total produced. A x P x Q finally gives the same result as in the Utilization formula above.
Your machine monitoring system can give you the Utilization report automatically, for every shift, day, week, month, etc.

Konfusion in Kolkata loo
What if you entered a restaurant’s loo, and the first thing you saw was the things in the picture below ? Maybe you’d think they were urinals of some weird new shape ? That’s what a customer in a restaurant in Kolkata thought too. These things are what you see first when you enter the men’s loo. A colleague of mine and I went to the loo, saw these things, and a man peeing into one of them. We also happened to look towards our right and saw a bank of what appeared to be the actual urinals (the second picture), partially hidden behind a wall. Obviously the first ones were wash basins.
I pointed out the mistake to the man peeing into one of the washbasins. I’m sure there wasn’t a more sheepish looking guy in Kolkata that night (although I don’t blame him, poor guy – the washbasins do look like urinals). I don’t remember which of the washbasins the guy peed into – would have helped so I can avoid it on my next visit to the restaurant. Luckily for me, the food in the place was so foul and expensive that I’m sure I won’t be going there again.
