by Caroline Heins, Daniel Jarr, Cornelius Herstatt
Abstract: Existing research regarding innovation widely assumes physical, in-person exchange. This cannot be guaranteed during a global pandemic like COVID-19, where people must work remotely, and are limited to virtual collaboration. Our paper is based on an exploratory action research in a multinational corporate operating in the material handling industry. We present a case study combining innovation methods with remote delivery. The action research was conducted between March and July 2020, and resulted in a novel approach for virtual innovation, which we call the Xtreme Design method. It has two advantages over traditional innovation methods: teams can innovate in a virtual remote work environment, and it is fast and cost efficient. We present the model and its elements, as well as the set of practices designed to realize it. For practitioners, the paper provides evidence and insights about the use of Xtreme Design to support the implementation of virtual innovation processes.
