FUTURE DEVELOPMENT OF RESEARCH

The limitations of this work also guide the direction of its future development. My biggest concern related to empirical research is the sole usage of survey data in a cross-sectional research design, as the intention to do something does not automatically lead to a specific behavior, and, depending on the area of application, behavioral intention of an IT decision maker might not even be a good predictor of actual behavior, especially in the case of organizational change. Therefore, in my opinion, to truly do empirical research, it is necessary to measure actual behavior in a longitudinal research design. Hence, future work should try to include these considerations when gathering data. In addition to the problems resulting out of the cross-sectional study design, I now see the usage of “arm length” research methods with skepticism. It is possible that a lot of results in the empirical domain are due to common method variance. Therefore mixing in “hard data points” or including experimental elements might reduce this bias, raising the validity of the results.

Beneath these methodological issues, future work should focus on finding true differences in the continuance of on-premise ES and on-demand ES. Hence, the survey should be distributed among organizations which have installed on-premise ES and group differences between both should be analyzed. There should be significant differences between the impact of e.g.

variables like system investment and technical integration between both deployment modes.

In addition, the differences in evaluation of success between both technology foundations, including their benefits and success factors, should be studied.

From a theoretical perspective, the focus should lie on building a model which is more parsimonious and does not need to include various variables from distinct models. Therefore, one should seek for stronger a priori theories explaining a higher portion of the variance with less included variables. For instance, institutional theory might better help to predict organizational level continuance than the socio-technical approach applied in this thesis.
