There's an interesting study that was done with 5 monkeys in a cage with a banana hanging from the top. I won't go into all the details of the study, but I'll try and give as quick of a summary as I can. Basically, each time a monkey reached for the banana, all the monkeys were sprayed with cold water. Eventually they all learned to not try to get the banana. One monkey was switched out for a monkey that had not been in the cage before, and when he reached for the banana, all 4 of the other monkeys stopped him. When a second monkey was switched out, and he tried to reach for the banana, the other 4 tried to stop him, including the one who had not been sprayed with water before. Eventually, all 5 monkeys were replaced by monkeys who had not been sprayed, but they still would not touch the banana.

There's a lot of interesting things to be drawn from this study, but I wanted to focus on the idea of letting go of our preconceptions. Doing something because "that's how it's always been done," might be one of the worst reasons to do something. Now, this obviously isn't to say that anything that's old is inherently bad, just that if you continue to do something for no reason other than "That's what you've always done," you're probably not using the most efficient of effective method. 

BI tools allow us to see not just what is going wrong in our operations, but why it is going wrong in the first place. This is where its real strength lies. Finding problems and their sources allows us to quickly and effectively determine our actions, allowing us to get back to making money. Like attacking the disease instead of the symptom, we can effectively eradicate our problems faster and easier, but we must ignore the impulse to continue to uphold tradition and keep the status quo.
