The purpose of this type of critique is to help the recipient improve and ensure that the same mistake will not happen again. Remember that it has to be a two-way conversation.
Focus criticism on behaviors that the other person can change. Do not compete with the other party; compete with the other person against the problem. Criticism can be promoted if the critic first invites criticism of his or her own behavior.
Think of it as imparting a lesson, rather than making someone feel down. A rationale for the giving of and the reception of constructive criticism are offered.
By inviting criticism, a person can create a situation in which her or his criticism of another is perceived as appropriate. When discussing the situation, get input from the other party.
