Assumptions: Management's Achillies Heel

"The least questioned assumptions are often the most questionable."

Paul Broca
20th century French physician, anatomist, anthropologist

While I don't know for certain, I am willing to bet that more plans fail due to faulty, unchecked assumptions than for any other single reason.

In other words, planning the future on faulty foundations.

And I would also bet there is a linear relation between unchecked assumptions failing, the more certain those who made them were that they were correct.

I'll have to check that.


  1. "I already know that", speaks volumes about a manager.

  2. Measure twice, cut once.
