A comparison between existing understanding of TACT and our implications

DimensionExisting understandingOur implications
Application contextPredominantly employed to examine conventional IT-use settings and specific IT artifacts like enterprise systems or wearablesExtends TACT to the fluid, non-territorial context of hot-desking, broadening the theory's scope to include socio-spatial work arrangements
Nature of constraintsOften treated as static limitations embedded within the physical or digital features of systems and artifactsReveals that constraints are socially constructed outcomes of everyday enactment, emerging dynamically when social norms are violated
Interplay of outcomesRecognizes the coexistence of affordances and constraints but often studies them as distinct consequences of useArgues that affordances and constraints are dynamically co-produced and intertwined, where one group's perceived affordance can become another's debilitating constraint (i.e. inversion)
Role of social behaviorView social context as a background factor influencing the interaction between users and IT artifactsPosition social enactment (e.g. senior staff “claiming” desks) as a primary driver that subverts intended digital affordances and converts them into social constraints
