This paper introduces the Harmonization Emergence Model (HEM), a model that integrates two key dimensions of harmony: Einheit(coalescing unity) and Stimmigkeit (congruent shared meaning). The HEM, in conjunction with John Boyd's OODA-loop, provides avaluable tool for comprehending how harmonization can emerge within complex endeavors that span organizational, linguistic,and cultural boundaries. By employing these models, our aim is to broaden the understanding of the imperative to shift the focusof Command and Control (C2), beyond mere direction and control towards a function for catalyzing and modulating collaborationamong organizations and actors within a specific context. Our objective with the HEM, is to better understand the 'power to theedge' concept and how C2 could facilitate assemblages (teams of teams) in actively engaging with and influencing the environment.This is guided by the pursuit of Congruence, which represents the metastable shared meaning we seek through Participatory SenseMaking.
