Based on our literature review and our previous research (Schubert & Glitsch, 2015) we define the term “collaboration scenario” as a composition of activities that are carried out by one or more people (actors) to achieve a common task (collaboratively). Collaboration scenarios describe the specific steps of the interaction among human actors and/or social documents involved in the joint work. Collaboration scenarios are generic components that can occur in different use cases. Collaboration scenarios include references to concrete software features and can be used to identify the necessary software. They can thus be used in the evaluation process as a link between use cases and actual ECS.
