Understanding User Participation and Involvement in Erp Use

User participation and involvement are being studied in the context of enterprise resource planning (ERP) systems and the research findings based on the data gathered till date are presented in this paper. Given the enterprise-wide scope of these systems and their high level of complexity, in addition to a different implementation methodology, differences in the nature of user participation and involvement were expected. Using Hartwick and Barki's model based on the theory of reasoned action a revised model was developed and tested empirically. While Hartwick and Barki's model explains user behavior vis-à-vis user participation and involvement, a more parsimonious model demonstrates that the usage dynamics in ERP implementation are indeed different. Given the mandatory nature of ERP usage, the subjective norm influencing behavioral intention concerning use may well be extra-organizational.
