Human resource interventions aim to help organizations improve performance and effectiveness. There are different types of interventions, including individual-based interventions like training and coaching, group-based interventions like team building, and inter-group interventions like conflict resolution. Effective interventions fit the organization's needs, are based on causal knowledge of intended outcomes, and transfer change-management skills to members. Designing effective interventions depends on factors like individual differences, organizational readiness for change, and the capabilities of the change agent.
