When working on tough problems, its easy for people in a team to have a different understanding of the issues, options, and trade-offs.
Allow no confusion.
Don’t accept it.
Banish it.
When you feel like you don’t get it, or see that someone else in the team is struggling to understand, keep asking questions and being curious until everyone in the room understands.
Too many mistakes are made due to people assuming everyone else knows what is going on.
