Conflict arises from incompatible goals, interests or values between individuals or groups. It can be constructive by improving decision making or destructive by hindering performance. There are various models of the conflict process including potential opposition, cognition, intentions, behaviors and outcomes. Conflict may be stimulated functionally through approaches like devil's advocacy or dialectical debate. Dysfunctional conflict should be managed through addressing personal or structural causes, using third party assistance, and integrative or distributive negotiation techniques. Overall, optimal organizational performance requires managing conflict at a moderate, constructive level.
