Despite these results though, no support was found for hypothesis H4, or H7,which predicted that the link between MRI and departmental performance would be stronger under both high task variability and high task difficulty, respectively.
All linkages from MRI to departmental performance were highly significant, but no differences for the path coefficient p32 emerged (via the Chow test) between the low and high sub-samples for either task uncertainty variable.
Once again, these results suggest that the initial benefit of changes in MACSs in our sample is to produce and communicate relevant information to managers.
As anticipated by all normative accounts, it appears that once managers have the appropriate information they utilize
it to enhance the operational objectives of their departments without regard to the nature of task uncertainty.
