This document discusses different classifications of organizational development (OD) interventions: 1) Team-building activities focus on enhancing team effectiveness through improving tasks, skills, relationships, and performance. Different types of teams require different interventions. 2) Intergroup activities improve effectiveness between interdependent groups through joint activities and considering groups as a single system. 3) Third-party peacemaking interventions involve a consultant helping two individuals in an organization manage interpersonal conflict through confrontation and understanding conflict processes and resolution. The interventions have potential to control or resolve conflicts.
