Outside-in Open Innovation focuses on tapping into the external pool of knowledge provided by partners, customers, universities, public institutions, etc. in order to improve the firm’s own innovation performance. Outside-in Open Innovation does not narrow down to acquiring the largest amount of external information possible. Firms also need to migrate the acquired data into their own R&D process in a way, which will add value to the company’s activities. This mix-and-match task is a matter of absorptive capacity – the quantity of valuable information a company can identify, assimilate, transform, and apply into its business process. The absorptive capacity is related to a number of factors such as an employee’s competence, financial resources etc. and can be perceived as the point at which additional open innovation becomes unproductive and even harmful for the firm. Simply put, absorptive capacity is about the clear assessment of what intellectual property a company has and what intellectual property it needs. Thus, participation in Outside-in Open Innovation initiatives should always be accompanied by a clear perception of the firm’s absorptive capacity in order to avoid negative outcomes.
