Former secretary of state Colin Powell: His 40-70 rule says that leaders should be taking decisions when they have between 40-70% of the information required for taking a decision. According to him, when you take a decision with less than 40% information, then you are shooting from the hip, which literally means to speak or act quickly based on first impressions, without carefully studying the background information.

I like this rule a lot. You don’t need too many details, you also don’t want to make a decision by having too little data.
40-70%? That’s the sweet spot.
