Although past studies have identified improvisation as an important element in the design and use of information systems (IS) [1-3], few have conducted in-depth investigation into the factors that influence it. In this paper, we seek to fill this research gap by formulating a framework, which identifies and organizes these factors into a dynamic model. The model provides an integrated framing of antecedents that affect the improvisation process and drive improvisations into punctuated organizational changes. Our Improvisation Dynamics Model defines the frequency, type and evolution of improvisations during the design and use of IS. We offer this framework as a means of clarifying the connections between user improvisation, IT system design and organizational change. This research represents an initial step towards formulating a theory of improvisation dynamics and it serves as a starting point for the study of the evolution of IS use and software. Our goal in the ongoing theory-building process will be to create a deeper theoretical model, which will help explain the connections between user improvisation and information systems evolution.
