ORGANIZATIONAL CONTEXT, USER INVOLVEMENT, AND THE USEFULNESS OF INFORMATION SYSTEMS*
研究了34家公司118位用户管理者，发现用户参与系统设计与实施能提升感知有用性，但组织因素并非通过影响参与来起作用，而是直接或调节参与与有用性的关系。
ABSTRACT This study investigates organizational factors related to user involvement in information system development and perceived system usefulness. Using a sample of 118 usermanagers in 34 companies, the results show that user involvement in design and implementation is related positively to users' perceptions of system usefulness. However, organizational factors were not found to be related significantly to user involvement, as had been originally hypothesized. Rather, organizational factors either had a direct relationship with perceived usefulness or moderated the relationship between involvement and usefulness. Two factors reflecting an MIS department's maturity (size and age) were found to reduce users' perceptions of system usefulness. Also, users at higher levels and those making more structured decisions found their systems more useful, although the user's level was found to moderate perceptions of system usefulness during the design stage. Three other organizational factors (level of MIS manager, MIS department scope, and decentralization of authority) also were found to have moderating effects.
