Since the beginning of Business Information System (BIS) development, the problem of end-user involvement in the system design and implementation has been discussed. For years, BISs for users have been changed into the systems constructed by end-users. The Web 2.0 technologies should strongly support this tendency. The paper aims to answer the question if end-users are involved and actively participate in BIS development processes. The paper covers results of the survey done in 270 companies in Poland.
