The findings from this study need to be interpreted within its limitations. First,
derived from cross-sectional data, the significant results found herein proved only
association, not causality. Second, the study relied on perceptual data collected from
single informants in measuring the independent and moderating variables. Data
collected in such a manner may be subject to the respondents’ cognitive biases and
distortions. On the other hand, by employing objective measures of the performance
and control variables, the study reduced similar biases and inaccuracies in collecting
the data for those variables and avoided the problem of “common method variance.”
Another limitation of the study lies in the coarse measures of the key variables. Future
studies need to develop and use more fine-grained scales to measure IS support for
product innovation as well as the complementary organizational resources.
