The practical adoption data-driven technologies in organizational contexts remains limited. Prior research emphasizes human-centered considerations as one reason. However, focusing on usability at the level of interfaces or explainability has proven inadequate to capture the broader socio-technical conditions under which technologies become applicable, adoptable, and valuable. Focusing on Small and Medium Enterprises (SMEs) in the engineering domain, this paper introduces a hierarchical construct that conceptualizes usability as a structured decision logic spanning suitability, compliance, and usefulness. The concept introduces two key contributions: (1) a hierarchy of necessary conditions that govern technology adoption, and (2) a temporal perspective on when different usability-related aspects can be meaningfully evaluated during technology development.
