This thesis focuses on designing a process for balancing and prioritizing the digital innovation project portfolio of a rental equipment company. The company operates in a traditional industry in which themes like digital transformation and digitalization are new emerging themes that are yet to be accepted by the industry. Therefore, in order to keep their businesses future proof, rental equipment companies need to focus on planning their digital project portfolio to meet their strategic requirements. This research was carried out in collaboration with Riwal Holding Group, a specialist in ariel work platforms (AWP) to design a process to manage their digital project portfolio and to check how feasible the process would be in a real-life setting.
