Companies need to regularly question their existing business and adapt their future strategy along technological, societal, or economic forces that may lead to the decline of entire industries or to the advent of completely new businesses. This lecture addresses this challenge and presents various tools companies can apply in order to detect future opportunities and ensure their long-term survival. The lecture presents customer-related tools, environment-related tools, and firm-related tools. Among others, the technology-opportunity matrix, big data approch, and innovation crowdsourcing will be discussed and applied in detail. The lecture builds on current insights from both academic and practitioner literature.
