Moving Toward Mission-Critical: The Migration of Strategic and Support Systems
Abstract
This research proposes a model of the dynamic relationship among information systems in the strategic, mission-critical and support categories. Findings suggest that systems in the support and strategic systems categories inevitably migrate to the mission-critical category, ultimately weighting IT portfolios toward mission-critical systems. Movement of systems among categories and the tendency toward a preponderance of systems in the mission-critical category have implications for practitioners charged with system planning and prioritization, system design, and resource allocation. These implications are explored.
