Conflict arises from incompatible goals, interests, or methods between two or more parties. It progresses through latent, perceived, felt, and manifest stages. Causes include differing values, assumptions, expectations, backgrounds, and abilities to handle conflict. Conflicts can be relationship-, data-, interest-, structural-, or value-based. Resolution techniques are problem-solving, avoidance, smoothing, compromise, and confrontation. While traditionally viewed negatively, modern perspectives see conflict as natural and sometimes necessary for growth.
