Explanation:

Two pioneering books published in 1984 arguably launched the field of strategic human resource management (SHRM). The first is Strategic Human Resource Management by Fombrun, Tichy, and Devanna; the second is Managing Human Assets by Beer, Spector, Lawrence, Mills, and Walton. This article provides a 30th anniversary review of the two books, partly to honor their pioneering contributions but also to use them as a lens for examining how the field has subsequently evolved and developed. Two recently published SHRM books are used as a benchmark for this analysis. The review identifies areas of SHRM constancy and change, major theoretical and empirical innovations, and newly developed research questions and directions, largely in an American context. Diagrammatic models of SHRM are synthesized and compared from the four books; also, nine specific dimensions of evolution in the field are highlighted with discussion of advances and shortcomings.
