Everyone know about Pareto principle or more commonly known as 80/20 law. In most of the company 80% job are done by 20% of worker.
But I would like to further the effect of Pareto principle.
80% of the 20%-worker's time is used to wait for 20% of 80%-worker's contribution.
Thus, the actual production rate is only 20% x 20% which is 4%.
It just happen here. We had wasted 1++ hour just to wait for a stupid bugger come and give us a permit to go into their premises. Shit!
