Simply put: innovation isn’t what innovators do; it’s what customers, clients, and people adopt. Innovation isn’t about crafting brilliant ideas that change minds; it’s about the distribution of usable artifacts that change behavior. Innovators—their optimistic arrogance notwithstanding—don’t change the world; the users of their innovations do. That’s not a subtle distinction.
