This white paper discusses the GEAR framework, which serves as a catalyst for sustainable digital transformation. It addresses the challenges organizations face due to fragmentation in digital transformation efforts, where traditional enterprise architecture practices often lead to static and disconnected documentation. The GEAR framework integrates the Open Digital Transformation Architecture (O-DXA) with the FORGE execution methodology, promoting a holistic approach that transforms architectural models into dynamic guides for organizational change. It emphasizes a shift from 'Architecture as Documentation' to 'Architecture as Execution,' allowing organizations to use enterprise architecture models as active tools for ongoing transformation. The paper outlines the implications for organizational leaders, highlighting the importance of collaboration, operational coherence, and strategic alignment in overcoming governance challenges. It also provides actionable processes that focus on execution, enabling enterprise architects and digital transformation leaders to drive significant business impact.
