Yosef Jabareen proposes a new qualitative method for building conceptual frameworks for phenomena linked to multidisciplinary knowledge. He redefines key terms such as concept, conceptual framework, and conceptual framework analysis. A concept is defined as having components that define it, with characteristics that include history, components from other concepts, and relationships to other concepts. A conceptual framework is a network of linked concepts that provide a comprehensive understanding of a phenomenon. It is not merely a collection of concepts but a construct where each concept plays an integral role. Conceptual frameworks are not causal/analytical but interpretative, aiming to understand rather than predict. They are indeterminist and do not enable prediction. Conceptual frameworks are developed through qualitative analysis and are based on concepts rather than variables. They are not determinist and are flexible, allowing modification based on new data and evolving phenomena. The article outlines a process for building conceptual frameworks, including mapping data sources, extensive reading and categorizing, identifying and naming concepts, deconstructing and categorizing concepts, integrating concepts, synthesizing and making sense of them, validating the framework, and rethinking it. The case study focuses on sustainable development, identifying seven concepts: ethical paradox, natural capital stock, equity, eco-form, integrative management, utopianism, and global political agenda. These concepts are interwoven and form the theoretical foundation of sustainable development. The article concludes that conceptual frameworks are essential for understanding complex, multidisciplinary phenomena and that the proposed method offers a flexible, interpretative approach to building such frameworks.Yosef Jabareen proposes a new qualitative method for building conceptual frameworks for phenomena linked to multidisciplinary knowledge.
