The document discusses the different levels and sources of conflict. It describes six levels of conflict from the macro level of large organizations down to the intra-individual level of internal personal conflicts. Interpersonal conflict can arise due to personal differences, information deficiencies, role incompatibility, or environmental stress. Intergroup conflict is more likely due to task interdependence between groups, status struggles, competition over limited resources, or ambiguous responsibilities. The document also outlines the three stage process of conflict from the initial potential opposition arising from communication breakdowns, personality traits or organizational structure, to the personalization of conflict into perceived or felt disagreement, and finally the intentions or decisions about how to respond.
