The document discusses a study examining how social media facilitates tacit knowledge sharing among public sector professionals. It provides background on the study, which is part of a larger doctoral thesis. The study aims to understand how social media enables tacit knowledge sharing and what contextual factors support this. A literature review identified themes of social media affordances and the concept of "Ba," which refers to a shared context for knowledge exchange. An online survey of over 1,000 professionals found that a social platform facilitated learning, expertise sharing, problem-solving, and innovation by enabling interactions and visibility of tacit knowledge, though it did not notably increase productivity. Findings provided insights into how social interactions and different types of "Ba" support tacit knowledge
