| The case study method of organizational research can be applied to foster optimal learning from actual human resource and organization development and change (OD & C) interventions. Furthermore, case studies can demonstrate the efficacy of alignment and convergence of theory and practice in the fields of Human Resource Management (HRM), Human Resource Development (HRD), and Organization Development (OD). The purpose of this study was to demonstrate how such a convergence in theory and practice can provide critical mass for lasting beneficial change in complex organizations, while also demonstrating the efficacy of case study designs, including both qualitative and quantitative inquiry. An overview of intervention theory and practice was provided, followed by a historical and theoretical survey of the convergence of HRM, HRD, and OD. Specific assessment and intervention methods applied in the cases were explained, recognizing the often inseparable nature of assessment and intervention in OD & C practice.;Three detailed cases were presented, all with qualitative data, and two with significant quantitative descriptive data obtained through organizational surveys. The organizations studied were diverse, yet common themes permeated individual behavior and group dynamics in the context of organizational culture. All three organizations were undergoing paradigm shift change. Two were touted as organizational experiments. In all three leadership made the decision to deploy a complement of HRM, HRD, and OD & C measures to address pressing needs. While leadership was not a central focus of the study, leadership was clearly evident in its influence on success with organizational change.;Cross-case analysis and synthesis was presented to demonstrate validity and answer the fundamental question regarding the efficacy of multiple converging or complementary HRM, HRD, and OD & C interventions. The case experiences demonstrated the potential leverage of critical mass for change that can be gained from plural paradigms, diverse disciplines, and inclusive intervention methods. |
