Teamwork has become increasingly important in modern businesses, and collaborative information systems (CIS) that support teamwork have become critical tools. Our study investigated the factors involved in team members' decision-making in a team context. We used the technology acceptance model (TAM) as a basis and incorporated the team-level factors of consensus on appropriation (COA) and cooperative team norms (CTN) into the model. Questionnaires were sent to project team members working in mid-sized to large businesses in Taiwan, and 134 valid surveys were collected and analyzed with partial least squares. Our results showed that CTNs have no effect on personal intention to use CIS but that they do affect perceived usefulness of CIS. COA has a direct effect on perceived usefulness as well. Perceived usefulness worked as a mediator between COA/CTN and perceived performance of the system. Perceived performance was strongly affected by perceived usefulness. The paper contributes toward a better understanding of information technology adoption with regard to team-level factors. Implications for future research and management practice are discussed.
