I heard a great analogy today that answers the objection that it takes too much time to seek an associate's perspective during a performance conversation. You've probably heard that concern or maybe even said it yourself.
THE ANALOGY: In a parade, is there any difference in the time it takes for the grand marshal or the sweeper (you know the one that walks behind the horses, or worse the elephants) to finish? Of course not, it takes them both the same amount of time, but for one it's a much more pleasant journey.
In tough conversations, when you take the time to seek the other person's point of view it may feel like it takes longer at first, but in the end it works out the same and you have a lot less clean up to do.
