Recent advances in social media technologies offer a variety of tools for virtual teams to share knowledge among their team members and develop transactive memory systems (TMS). Adopting the media affordances lens, the current study investigates how social media affordances affect individual evaluations of TMS development and perceived team effectiveness in virtual teams. Survey data from 339 virtual team members across 92 hackathon events reveal that types of affordances have differing impacts on each of the three dimensions of TMS (perceptions of accuracy, sharedness, and validation). Furthermore, each dimension of perceived TMS mediates the relationship between its related social media affordance types and perceived team effectiveness. These findings suggest that virtual teams may need to adopt different social media technologies depending on which aspect of TMS development is prioritized.

社交媒体技术的最新进展为虚拟团队提供了多种工具，以在其团队成员之间共享知识并开发交互记忆系统 (TMS)。本研究采用媒体可供性视角，调查社交媒体可供性如何影响虚拟团队中 TMS 开发的个人评估和感知团队效率。来自 92 次黑客马拉松活动的 339 名虚拟团队成员的调查数据显示，可供性类型对 TMS 的三个维度（准确性、共享性和验证的感知）中的每一个都有不同的影响。此外，感知 TMS 的每个维度都调节其相关社交媒体可供性类型与感知团队效率之间的关系。
