Knowledge sharing among software developers enhances the success of software design and implementation. However, there is an inadequate understanding of how communication factors such as negotiation and reciprocity impact the knowledge-sharing process within software development teams and between team leaders and team members. The present study used a correlational research design to test the relationship between the reciprocity (i.e., communication between team members), negotiation (i.e., communication between team leaders and team members), and knowledge sharing to determine whether different types of communication influence knowledge-sharing outcomes. A cross-sectional survey was used to collect data from a target population of software developers.
