This paper focuses on agility in information systems, and how the IT function can enable this capability. IS theory and a best practice framework on agility are compared, and gaps are identified. A goal of the research is to reconcile the IS theoretical and practice perspectives. We illustrate that the cybernetic framework of Beer’s Viable System Model can be used to reconcile gaps between theory and practice, drawing on the cybernetic notion of control. The paper reports on a research project, where the findings from an applicability check with experienced IS practitioners are discussed, and a mailed survey to test the research propositions is outlined. From a relevancy perspective, the paper illustrates how theory can inform a high-ranking issue of IT management concern. Better agility outcomes from an extended best practice framework are anticipated.
