Zusammenfassung

In diesem Beitrag wird die Geschäftsmodellinnovations-Roadmap vorgestellt – ein neuer Ansatz für den Innovationsprozess von Geschäftsmodellen, der auf dem Roadmapping-Konzept basiert. Die Geschäftsmodellinnovations-Roadmap dient Unternehmen als Unterstützung dafür, digitale Technologien in ihr Geschäftsmodell zu integrieren und dabei die richtigen Ressourcen im Zeitablauf für die Umsetzung zuzuweisen. Als Methodik zur Entwicklung des Ansatzes wurde eine Kombination aus einer Delphi-Befragung und einer Aktionsforschungs-Komponentenstrategie angewandt. Die Fallstudie zur Aktionsforschung wurde in einem mittelständischen deutschen Unternehmen im Postdienstleistungsbereich durchgeführt. Im vorliegenden Beitrag werden die spezifischen Merkmale und Besonderheiten der Geschäftsmodellinnovations-Roadmap aufgezeigt. Die Experten sind sich einig, dass die vollständige Digitalisierung ausgewählter Geschäftsmodellkomponenten zu empfehlen ist, was mit der Geschäftsmodellinnovations-Roadmap dargestellt werden kann. Weiterhin geht aus den Ergebnissen hervor, dass die Integration von digitalen Technologien in ein Geschäftsmodell von einem strukturierten und übersichtlichen Ansatz profitiert. Der im Beitrag dargestellte, praxiserprobte Ansatz zur Geschäftsmodell-Innovation bietet Unterstützung bei der Entwicklung und der strategischen Verankerung von Digitalisierungspotenzialen im Geschäftsmodell.
