This paper is a foundation in the development of a conceptual framework examining the mediating role of institutional resilience in the relationship between transformational stewardship and development outcomes within higher educational institutions (HEIs). This paper proposes the RADIANT Model (Resilience-Adaptive Development through Integrated Administrative Navigation and Transformational Stewardship) as an integrative framework linking transformational stewardship, institutional resilience, and development outcomes, while factoring in governance rigidity as a moderating structural condition. Drawing on transformational leadership theory, stewardship theory, institutional theory, and the organizational resilience framework, this paper helps put together existing literature to argue that leadership practices influence development outcomes indirectly through resilience processes. This paper situates the analysis within the context of public universities in Nairobi, Kenya, where issues with governance and constrained resource allocation tend to heighten the need for resilient institutions. By conceptualizing institutional resilience as an intervening mechanism, the paper argues for a structured explanation of how leadership practices translate into measurable development outcomes. The paper contributes to theory, policy, and practice and proposes a foundation for future empirical validation.
