What is Actuality

The problem addressed is how to design rationally information systems for emergent organization. Complexity and emergence are new design problem that constrains rational design. The reconciliation of rationalism and emergence is achieved in the theory of deferred action by synthesizing rationalism and emergence. Theories on designing for normal organisation exist but most of them are borrowed from reference disciplines. The theory of deferred action is based in the information systems discipline and is presented as a theory to inform practice to improve the rational design of information systems for emergent organisation. It has the potential of becoming a reference theory for other disciplines in particular for organisation studies. As emergence is a core feature of complexity, the base theory for the theory of deferred action is complexity theory. The theory of deferred action explains the effect of emergence on the rational design of information systems. As a theory to inform practice it provides guidance in the form of design constructs on how to design rationally information systems for emergent organization.
