An enterprise social network (ESN) uses social media software to facilitate collaboration within a business. It allows for knowledge sharing, communication across geographical regions, and problem solving. An ESN can improve engagement, innovation, and flexibility for remote work. For example, Red Robin gave frontline employees a voice on Yammer to provide quick customer feedback and change their menu faster. ESNs are increasingly important for the post-COVID workplace as collaboration tool usage has risen significantly since 2019.
