The successful implementation of internal crowdsourcing (IC) in a company requires a precise description and definition of the personnel responsibilities for the various process levels and process components within each process phase of IC. As part of the research project ‘ICU—Internal Crowdsourcing in Companies’, we have developed a new role model for internal crowdsourcing based on a practical application of IC in the company GASAG AG, an energy provider located in Berlin, Germany. The aim of this article is to present the main features of this role model (Some aspects of this article will also be published in German. Please be referred to Daum, M., Wedel, M., Zinke-Wehlmann, C., Ulbrich, H. (ed.) (2020): Gestaltung vernetzt-flexibler Arbeit. Beiträge aus Theorie und Praxis für die digitale Arbeitswelt. Berlin: Springer Vieweg). It is based on the roles of the agile model of Scrum, because partial aspects of the internal crowdsourcing process and certain process steering tasks have similarities with the procedure and task descriptions of Scrum. Scrum, as a mature and practice-proven set of rules with role descriptions, rules, events and artefacts, provides helpful implications for the design of an internal crowdsourcing role model as we will prove in further detail.
