It has been argued that Enterprise systems (ES) implementations are overshadowed by a high failure rate despite their promised benefits. The factors accounting for ES failures are not limited to technical issues. Rather, there are various causes arising from the interactions among people, task, environment, and technology. One of the commonly cited reasons for ES implementation failures in the context of mandatory use is the user`s unwillingness to adopt or use the systems. Considering that the appropriate management of expectations may play an important role in forming positive behavior toward newly implemented systems and reducing unwillingness to adopt them, this study examines the effect of outcome expectation on the system use activity in the context of the mandatory use of information systems (IS) from the perspective of social cognitive theory. The user`s behavior depends on how the user appraises the expected consequences about the variety of events which occur in IS changes. We examine outcome expectation from the social cognitive theory perspective which suggests that it is a significant cognitive factor for individuals to control their behavior. Prior research on the adoption of new IS has been conducted in the context in which individual users adopt the new IS voluntarily and either usage or intention to use is exploited as a dependent variable. However, nowadays most enterprise-wide IS are used in a non-voluntary context where users are compelled to use the system in order to perform their jobs. Therefore, the use of either usage or intention to use as an appropriate surrogate variable for actual system use behavior remains contentious. With this background, we propose a construct called system use activity that is conceptualized by immersion, reinvention, and learning, and which can play a surrogate role to explain actual system use behavior instead of the concept of either intention to use or simple system usage. This study aims to investigate the role of outcome expectations in the successful use of IS and to suggest a new surrogate variable for system use in the mandatory use context. We have two research objectives. First, from the IS acceptance perspective, we examine how outcome expectations affect the IS use activity of the organizational members. Second, we suggest a new outcome variable describing actual acceptance behavior of the user in the mandatory use context. A field study was conducted using a structural equation model. The data used to test the proposed research model were collected from ERP system users who were believed to reflect mandatory system use context. A total of 145 complete and valid responses were obtained. The data were analyzed using a two-step methodology with LISREL 8.7. Structural equation model analysis provided significant support for the proposed relationships. The empirical results suggest that outcome expectations-personal and user satisfaction have positive effects on system use activity. Outcome expectations-performance and outcome expectations-personal show significant relationships with two aspects of system performance: system quality and information quality, respectively. User satisfaction has a significant impact on system performance. Theoretical and practical implications of the study are discussed, along with its limitations. Based on the study results, suggestions are made for improving system use activity in the mandatory use context of information systems.
