This chapter presents, analyses and discusses the case history of the BUFFL project, a Swedish two-year pilot project. The overall aim of the project has been to develop a national model for flexible, work-integrated professional development. A fundamental component in the project is the idea of organisations bringing their own data (BYOD). Case units were 14 course modules for banking and insurance company staff. Data about the course modules have been gathered from course evaluation questionnaires, and data about the support model are from e-mail interviews with 8 teachers. Considering the technical problems at some of the course starts the mean values from the questionnaires are surprisingly high, and especially for the BYOD concept. What many course participants perceive as a challenge is the relatively high study pace. Finally, the support model needs to be extended to better support the idea of a multi-directed, and work-integrated professional development.
