"If you do not manage Reliability Culture it may be managing you, and you may not be aware of the extent." - Terrence O'Hanlon

In a famous experiment a group of scientists placed 5 monkeys in a cage and in the middle, a ladder with bananas on the top.

Every time a monkey went up the ladder, the scientists soaked the rest of the monkeys with cold water.

After a while, every time a monkey went up the ladder, the others beat up the one on the ladder.

After some time, no monkey dare[d] to go up the ladder regardless of the temptation.

Scientists then decided to substitute one of the monkeys. The 1st thing this new monkey did was to go up the ladder. Immediately the other monkeys beat him up.

After several beatings, the new member learned not to climb the ladder even though he never knew why.

A 2nd monkey was substituted and the same occurred. The 1st monkey participated on [sic] the beating for [sic] the 2nd monkey.

A 3rd monkey was changed and the same was repeated (beating).

The 4th was substituted and the beating was repeated and finally the 5th monkey was replaced.

What was left was a group of 5 monkeys that even though never received a cold shower, continued to beat up any monkey who attempted to climb the ladder.

If it was possible to ask the monkeys why they would beat up all those who attempted to go up the ladder ... I bet you the answer would be ... "I don't know — that's how things are done around here"

Does it sound familiar?

Next time someone tells you “that’s not how we do things”, ask them why. If they can’t tell you, tell them about the 5 monkeys!
