Abstract—Boundary Objects (BOs) are means of communication support for teams. In eLearning projects, teams usually consist of people with diverse professional backgrounds and different experiences. Due to this fact, team members have different perspectives on the eLearning product or service to be developed – eLearning system development thus becomes a complex and demanding task. Using specific BOs in a purposeful way can help people to communicate and support interaction between team members. Amongst others, process models, scripts, patterns and architecture models have been investigated as BOs for eLearning system development)
