Good decision making requires evaluating the information you have on how your various options deliver against your objectives.
However, most people don't understand how they should analyze the information piece of a decision.
The first step is actually to identify what information you *don't* have.
Where are the gaps?
Can they be filled?
What would it take?
Would it change your decision?
Answer those questions, and you'll be able to take a more targeted approach, instead of falling into the trap of analysis paralysis.
