Final answer:
The performance of self-managed teams is best improved when economic rewards reflect the team's collective success and when teammates have overlapping areas of expertise.
Step-by-step explanation:
The performance of self-managed teams can be influenced by several factors, but when it comes to economic rewards, it's beneficial if these rewards depend on team performance rather than just individual contributions. This promotes team unity and accountability, as well as a sense of shared purpose, where each member is motivated to contribute to the team's collective success. Thus, economic rewards dependent on input from teammates can help improve the performance of self-managed teams.
Additionally, the presence of overlapping areas of expertise among team members can contribute to a robust and agile team dynamic because it promotes shared understanding and cross-functional support, which is also vital in enhancing team performance.
