The possible benefits of open source software (OSS) have led organizations into adopting a variety of OSS products. However, the risks related to such an adoption, and how to reduce these risks, are not well understood. Based on data from interviews, a questionnaire, and workshops, this paper reports ongoing work in a multi-national telecom company. The paper has three main contributions. First, it identifies and discusses several risks related to OSS adoption. Second, it identifies steps for reducing several of these risks. Third, it shows how research can be used to increase the visibility of, and involve the employees in, ongoing OSS efforts.
