Relying only on your R&D may seem sufficient. However, given that you must react as quickly as possible to a constantly changing environment, this will quickly become a way that will not be effective enough, and especially that lacks of "customer" focus. I advise you to look somewhere else. The open innovation concept, for example, suggests that innovation can be discovered with the help of external sources, such as your "non-technical" employees, other industry leaders, or even your customers.
Constantly receiving feedback, promoting collective thinking, or even creating a mutual innovation strategy with some of your competitors, can bring you closer to the disruption.
