The advantage of problem solving strategies is that they yield the, best outcomes. Mutually beneficial outcomes are more likely to last, to improve the parties relationship, and to benefit the wider society. Problem solving outcomes are likely to benefit both parties when the situation has high integrative potential and both parties have reasonably high aspirations. In addition parties must be firm about their aspirations or goals, but must be flexible regarding the means used to reach those goals. The risk of problem solving strategies is that they may backfire if the other side pursues a contentious strategy.
Contention seeks to persuade the other party to agree to a solution that favors one's own interests.
This strategy has also been called positional bargaining. Contentious tactics include inflated demands, irrevocable commitments, persuasion, and threats. Contentious strategies alone tend to yield poor outcomes. Contending may escalate a conflict. When outcomes are finally reached they may be low-level compromises.
