The nature of information system provision has changed as the business models of software firms are continually changing towards software-as-a service and platform-as-a-service solutions. Involving end users in a continuous development of such information systems promises to increase the overall system’s success. The conceptualization and actual realization of the user involvement concept is subject of ongoing research. Based on a systematic literature review, we identified three implications of this research that are relevant for the development of an information technology based assistant for user participation and involvement. In this paper, we introduce our Design Science Research project on the theory grounded design of a user participation and involvement assistant. We aim to enable end users to provide meaningful feedback to the developers during their actual system use. Moreover, the assistant will enable developers to effectively analyze the vast amount of complex end user feedback.
