Managing information technology (IT) human resources and skills presents a challenging task for executives. With IT skill shortages projected to reach unprecedented levels, making the right choices for IT human resource management is increasingly considered imperative for shaping a firm's competitive advantage. The complexity associated with the fluctuating demand for IT skills, coupled with dynamic and innovative approaches to short-term and long-term staffing, as well as the inevitable delays in skill acquisition, makes this a challenging task. This research attempts to examine the impact of potential staffing strategies under various conditions, and provide guidance for staffing decisions, using a systems dynamics approach. The model and accompanying simulation can serve as a practical decision support system for IT human resource decision makers.
