The Identification of Requirements for Enterprise Social Software (IRESS) model was created to help in the development of social software solutions(Schubert & Glitsch, 2015). It applies a task-oriented approach using the strengths of a systematic view to bring order to the rather unstructured field of collaboration(Schubert & Glitsch, 2015). Comparable to other models for business analysis (such as ARIS) the IRESS Model requires companies to analyse their business processes and use cases first, to establish an overview of their sequence of activities (process map) and their organizational units (organizational chart)(Schubert & Glitsch, 2015).
IRESS-Modell (Schubert & Glitsch 2015)
The bottom level of the IRESS model (collaborative features) draws on the 8C Model for Enterprise Information Management by Williams(2011). The top level contains business processes and use cases. While processes are based on the idea that the sequence of tasks is more or less predictable and stable (structured) it is likely that there is also project-oriented work going on in companies with a sequence that requires a higher degree of flexibility(Schubert & Glitsch, 2015). These flexible compositions of activities are addressed as collaboration scenarios and are on the second level. The process map and the overview of use cases serve as the basis for identifying candidate areas for collaboration that contain a high concentration of C4-activities (communication, cooperation, content, coordination). The identified business processes and use cases are analysed and their collaboration scenarios are identified. Collaboration scenarios are then matched with collaborative software components that can support the C4-activities. The mapping can be supported by use of an existing mapping table i.e. a Collaborative Scenarios Catalogue (CSC).
