“…With some exceptions (e.g., Welbourne and Cyr, 1999;Hope Hailey et al, 2005;Singh et al, 2012;Martin and Gollan, 2012;Sheehan et al, 2014;Chadwick et al, 2016), most studies of the so-called "black box" of the HRM -performance relationship focus upon HR practices (processes/systems/policies/strategies), rather than the role played by the HR department in making strategic HR decisions. On the other hand, the stream of research that focuses on the influence of HR department/professionals on strategic decision making on the board (e.g., Ulrich and Brockbank, 2005;Kelly and Gennard, 2007;Charan et al, 2015) tends to exclude a more indepth consideration of HR practices and their relationship to firm performance.…”
