Past efforts to relate the management of human resources to a firm's business strategy have taken three approaches: matching managerial style or personnel activities with strategies, forecasting manpower requirements given certain strategic objectives or environmental conditions, and presenting means for integrating human resource management into the overall effort to match strategy and structure. In this article, the literature on each of these approaches is reviewed, and a typology is presented that posits a reciprocal interdependence between a firm's business strategy and its human resources strategy. Implications for research and practice are discussed.
