This document summarizes a webinar presentation by Leonhard Dobusch on open strategy as a practice. The presentation discussed open strategy as balancing traditional exclusive business strategy with open innovation. It explored tensions that can arise from increasing openness, such as compromising speed or burdening wider audiences. The presentation also examined how openness and inclusion are connected, noting examples where open projects have lacked diversity. It argued that analyzing openness and closure as constitutive practices that are inextricably linked, rather than as opposing degrees, can help address issues of exclusionary openness.
