The contemporary business landscape is increasingly defined by the BANI (Brittle, Anxious, Nonlinear and Incomprehensible) paradigm, rendering traditional strategic management models, including those developed for the VUCA world, insufficient. Existing approaches are often fragmented and fail to address the systemic nature of modern challenges, creating a critical need for a new, holistic framework to ensure organizational resilience and long-term viability. This study aimed to develop an integrated strategic framework specifically designed to navigate the complexities of the BANI environment. This paper introduces an Integrated Strategic Framework for a BANI Environment; a novel conceptual model structured around four interconnected subsystems: Strategic Sensing & Diagnostics, Adaptive Flexibility & Agility, Strategic Foresight & Resilience, and a central core of Adaptive Leadership & Culture. Each subsystem is engineered to directly counteract a specific BANI challenge. To operationalize this framework, a comprehensive methodological toolkit was developed, including the BANI-Readiness Diagnostic Model with a detailed set of quantitative and qualitative indicators for organizational self-assessment. Furthermore, the framework’s dynamic nature is enabled by the Adaptive Strategic Cycle, an iterative five-stage process (Sensing → Interpretation → Modeling → Action → Learning) that transforms strategy from a static plan into a continuous process of learning and evolution. The developed framework provides a holistic and actionable solution for organizations operating in a chaotic world. It moves beyond reactive adaptation by equipping leaders with the architecture, diagnostic tools, and operational processes necessary to build proactive resilience and antifragility. The integration of these components offers a significant contribution to both management theory and practice, providing a robust roadmap for organizations not only to survive but to thrive amidst the profound uncertainty of the BANI era.
