Listen with an open mind, not a voting mind. (Voting minds are busy internally saying "I agree, I disagree." Open minds want to know what the person means.)
Acknowledge the person's statements with an honest, respectful comment, if only "That's an interesting thought."
Listen more than you talk
Pace the person's rate of speech, seating level, emotional tone, with elegance and honesty
Be trustworthy
Cultivate trust through self-disclosure
Tactfully, and early on draw your boundaries-"I really want to hear your concerns, and have only 15 minutes this morning. Should we set another time?"
Lead the conversation to common ground often-"We both want the customer to be happy with this project."
Connect comments with "and" instead of "but"- I understand how busy you are and it's extremely important that we meet this deadline."
Take time to review agreements on specific points, including who will do what next
