Data collection used a questionnaire mailed to managers of Thai agricultural cooperatives. Following the arguments of Sarantakos (1998), the questionnaire employs a five point Likert scale representing a range from "Strongly Disagree" to “Strongly agree" (other examples of information systems researchers who used Likert scales are Ng, Tye & Chau (1994), Thong & Yap (1995), Thong (1996 and 1999), Gover, Goslar & Segars (1995).
Pretesting and Piloting was used to refine the questionnaire. This was done in semi structure ways that enable discussion to occur on complex or misunderstand questions. Sarantakos (1998) and Lawrence & Keen (1996) recommended this is a way of improving question wording.
