This study focuses on the role of information systems development (ISD) control as a means to better understand the underlying elements of ISD methodologies. Based on Ackoff’s general systems theory, we propose a new typology of ISD control that moves beyond the de facto standard in ISD research: control modes. Through twenty-six interviews at four organizations, we find that our typology aids in distinguishing between control dimensions within structured and flexible development to a greater extent than control modes would allow. Our paper also discusses possible reasons why the benefits of agile development may become diluted in organizations where both flexible and structured methods are employed. This work contributes to the advancement of ISD control theory and provides useful insights for practitioners responsible for the governance of ISD projects.
