One of the biggest time consumers is the lack of decisiontaking. Managers should trust their data or their intuïtion and just decide what to do. What is the risk of this? Only a wrong decision. And then you can decide to do something else.

You want to save time and really take that decision and act upon it. That's the second timewaster in this case: once finally decided, the action lacks. So stop worrying and thinking but get your bum in gear!
