Forcing
Also known as competing. An individual firmly pursues his or her own concerns despite the resistance of the other person. This may involve pushing one viewpoint at the expense of another or maintaining firm resistance to another person’s actions.
Win-Win (Collaborating)
Also known as problem confronting or problem-solving. Collaboration involves an attempt to work with the other person to find a win-win solution to the problem in hand - the one that most satisfies the concerns of both parties. The win-win approach sees conflict resolution as an opportunity to come to a mutually beneficial result. It includes identifying the underlying concerns of the opponents and finding an alternative which meets each party's concerns.
Compromising
Compromising looks for an expedient and mutually acceptable solution which partially satisfies both parties.
Withdrawing
Also known as avoiding. This is when a person does not pursue her/his own concerns or those of the opponent. He/she does not address the conflict, sidesteps, postpones or simply withdraws.
Smoothing
Also known as accommodating. Smoothing is accommodating the concerns of other people first of all, rather than one's own concerns.
