Digital platform ecosystems have redefined firm boundaries, transforming competition into coordinated networks of interdependent actors who jointly generate value through platform participation. This conceptual article addresses a critical gap in the literature by developing an integrative framework that explains how firms can strategically engage in these ecosystems while managing complex interdependencies with platform leaders and complementors. By synthesizing foundational insights on ecosystem theory, platform meta-organizations, complementor engagement, governance mechanisms, and value co-creation, we identify the need for a holistic model that goes beyond isolated strategies. We introduce the strategic interdependence orchestration framework (SIOF), a novel architecture comprising five interconnected components—ecosystem role positioning, interdependence mapping, governance mechanism deployment, complementor coordination protocols, and value co-creation pathways—supported by adaptive feedback loops. The SIOF positions ecosystem participation as a core competitive strategy, enabling firms to convert interdependence risks into sustained value advantages within platform-centered networks. By theorizing the relational flows of coordination, governance, and learning, this framework advances platform strategy research and offers actionable guidance for firms navigating digital ecosystems. A detailed conceptual diagram illustrates the architecture, highlighting dynamic relationships and feedback mechanisms essential for long-term ecosystem success.
