Growing numbers of companies are implementing enterprise social software (ESS) in its various forms. The adoption and use of those information systems (IS), such as wikis, weblogs, social network- ing sites, or platforms that combine and integrate various of those IS, is said to have various kinds of impact on organizations. Such impacts include increased productivity or improved innovation levels. In our study, we aim to provide a more holistic overview of the various outcomes of ESS use. In doing this, we conduct a literature review to collect a list of ESS use outcomes, and apply coding techniques to categorize and order these outcomes. Our study contributes to both theory and practice: Our un- derstanding of the outcome perspective of ESS use is advanced, thus answering various calls for re- search, and management of the value creation process becomes more transparent and more feasible due to the introduction of ESS.
