Knowledge sharing may also lead to improved coordination because of the development of transact memory, defined as the knowledge of “who knows what” in a team. Transact memory begins to form when individuals learn something about the domains of expertise of other team members. With the formation of transactive memory, coordination is likely to improve because workers can anticipate each others’ behavior. Lewis (1999) argued that repeated interactions facilitate learning about other members’ areas of expertise when team members disclose information indicating their specialized knowledge. She found that knowledge exchange in teams led to the formation of transactive memory, which was instrumental in higher performance. Therefore, the above arguments suggest that knowledge sharing is likely to lead to higher performance
