This is a fantastic trait I learned from this essay today. Almost step by step:
Step 1: build a team
Step 2: set up a meeting
Step 3: Listen to EVERY voice in the meeting, give EVERYONE a chance to speak and fearlessly press opinion
Step 3a: Allow at least one contrarian in the team
Step 4: Get all the facts, match them, listen to experts
Step 5: Make a decision matching your own thoughts and philosophy about the right thing to do!
