Healthcare is undergoing rapid digital transformation through innovations such as AI-assisted diagnostic systems, telemedicine, and electronic health records. However, prior research suggests that many of these investments fail to deliver the expected clinical, operational, and financial value. This underperformance is often driven less by technical limitations than by managerial gaps, including strategic misalignment, governance deficiencies, and organizational resistance. This study proposes the Holistic Digital Transformation Management (HDTM) framework (BDDY in Turkish), which integrates technology selection, change management, and value realization within a unified strategic management perspective. Grounded in an integrative literature synthesis, the framework was developed through traceable consolidation of findings from diverse theoretical traditions. Unlike existing frameworks that explain why digital transformation fails, HDTM prescribes how it should be managed — offering a structured decision–input–output logic across all four phases, while explicitly addressing the sociotechnical complexity of healthcare environments, including multi-stakeholder dynamics, professional resistance, and clinical workflow integration. The framework comprises four iterative phases: (1) Strategic Alignment and Requirements Analysis, (2) Technology Evaluation and Selection, (3) Implementation and Change Management, and (4) Value Realization and Optimization. By framing digital transformation as a continuous sociotechnical management cycle rather than a one-off IT installation project, the model provides healthcare managers with a practical roadmap to govern adoption and sustain measurable value creation, while also offering a testable theoretical foundation for future empirical research.
