Institutionalizing organizational change has emerged as an issue among organization researchers and managers alike. Institutionalization of change is derived from change management theory in its emphasis on understanding the roots of organizational success and failure. The field of HRD appears particularly poised to help organizations institutionalize change. The purpose of this study was to identify what HRD interventions are being used to institutionalize organizational change in multinational corporations (MNCs). This paper presents empirical findings on the use of Cascade Training along with other methods, and the nature of significant differences found among companies from the four countries in their use of the HRD interventions.
