Large, complex information systems (IS) have become prevalent among organizations seeking the benefits of an integrated information environment, with a single data store. These systems are costly to implement and require the full participation of users during post-adoption in order for organizations to achieve maximum value from the IS investment. Some end-users exhibit a strong negative emotional response to the technology, including anger and frustration that may lead to refusal to use the system, even in a mandatory use environment. Other end-users exhibit more positive emotional reactions, leading toward a willingness to incorporate the new IS into their work routines, even when the system is poorly designed or implemented. In this initial work, we suggest that the different end-user responses may be attributed in part to the users’ Emotional Social Competency in conjunction with their individual Technology Readiness response. We develop these ideas into a multi- dimensional construct, called Socio-Technical Competency and suggest a potential research model.
