The data used in validating the research model were gathered as part of a research project on IIS implementation.
A field survey was conducted to create a large, statistically testable sample with which to test the significance of relations among variables.
A face-to-face interview using a structured questionnaire was the main method of data collection. The mail survey method was avoided, because of the difficulty in obtaining reliable responses from the questionnaire, which addressed such sensitive and confidential issues as the implementation performance status of IS. On the other hand, personal interviews stimulate trust and cooperation, which are prerequisites to obtaining sensitive information about control systems. In addition, it was important to ensure that these items can be answered by IS practitioners. Interviews provided the opportunity to aid the respondents in their interpretation of the questions and to allow flexibility in determining the sequence and wording of questions.
