Média versus discrepantes

Um excelente conselho de Roger Martin, mais um, acerca de pensar estratégia.

"I am utterly tired of the modern strategy focus on averages, whether means, medians, or modes.

...

In world of strategy, all analytical guns have long been trained on means, medians, and modes.

...

The flip side of obsession with averages is aversion to the outliers. They are largely ignored if not entirely suppressed.

...

There is a cost to this aversion. While the mean tells you about what is operating today, outliers give you hints about the future.

...

The problem is that our analytical mindset and toolbox has migrated away from paying attention to the outliers. 

...

The single most important thing to do is to think consciously and carefully about when you pay attention to averages and when to outliers. When you want to hone and refine what is, focus on the averages and ignore the outliers. Outliers will distract you when creating improvement for the middle of the distribution is your goal.

...

If you want to figure out what could be, you have to pay attention to the outliers."
