Second, the DCR effectiveness measure assumed that client departments had the greater responsibility for exercising DCRs. (No such assumption was made in the DMR exercise effectiveness measures.) This assumption fails to fully account for self control through which IT departments also share some of this responsibility. This assumption does not severely threaten the findings because self control has been found to be used only to a limited degree, and its relationship with performance remains empirically untested. However, caution is warranted in asserting that the client department exercised DCRs because the average value of DCR decentralization is 3.76, which suggests that they are close to the midpoint of the scale but skewed slightly towards IT. It is plausible that this skewing arises from the use of IS directors as the primary informants.
