“Do not attack a person—only a behavior—it’s easier not to become defensive.”
“We are not just our behavior, we are the person managing our behavior.”
There are not just One Minute Praisings, but also One Minute Reprimands. What is very important when using them is to let people know that they are going to be reprimanded. It should be done immediately and very specifically. Besides describing what they did wrong, it is important to say how you feel about it. This is the first part of the reprimand and should not take more than 30 seconds. In the second part, shake hands, remind them how valuable they are to the company, and that you are commenting only the behaviour not them as a person. Remember that when the reprimand is over, it is over.
