This chapter introduces knowledge bridging as the competency that enables individuals and organizations to connect fragmented expertise across professional, organizational, and technical boundaries. It presents four knowledge bridging modes—Translator, Coordinator, Connector, and Designer—organized along two dimensions: people- versus process-focused and understanding- versus implementation-oriented. Each mode contributes differently to reframing: translators convert meaning across disciplines; coordinators align people and timing; connectors embed routines that sustain collaboration; and designers create structures that foster shared understanding. Through examples from national security, business, and healthcare, the chapter illustrates how each mode can facilitate or hinder reframing depending on how it is applied and supported. When these modes function effectively, knowledge flows freely, diverse perspectives integrate, and problem understanding evolves dynamically. When neglected or rigidly applied, misalignment, fragmentation, and stalled reframing result. The chapter concludes by examining trade-offs such as clarity can become oversimplification, structure can breed rigidity, and emphasizes that mastery lies in orchestrating these modes fluidly to fit the context. Knowledge bridging transforms reframing from an individual insight into a collective, systemic process, turning distributed expertise into coherent, actionable understanding across complex human-AI and organizational ecosystems.
