In conclusion, the results of this study add to our knowledge about the
multi-factorial nature of a relatively new field called E-HRM. Technological,
organizational and human factors all appear to be equally important and to
mutually influence each other during implementation. The fact that variables derived
from these very different factors all contributed to the explanation of variance in
attitude towards E-HRM, favors multi-factorial theorizing as a starting point for
studies in this area (Hempel, 2004; Rue¨l et al., 2004). In this study IT experiences and
HR role preferences were treated as complementary, e.g. additive, in their effects on
attitude towards E-HRM. For experienced usability and strategic preference the
strongest effects were found. As stated in the introduction, it is exactly these two
variables that one might consider related, as usability of E-HRM applications may be
considered especially positive by individual employees that prefer non-employee
champion types of activities, e.g. activities that more easily lend themselves to HR
delivery through E-HR channels. In future research, the possibility of an interaction
between these two aspects deserves further attention, both theoretically and
empirically.
