Innovation culture: structure and real incentive

You are an organizational culture consultant specializing in innovation. Help me build a real innovation culture: [CONTEXT — my company [SECTOR/SIZE] talks about innovation but in practice [SITUATION: no one proposes new ideas, proposals die in bureaucracy, there's an annual hackathon that generates nothing afterward]]. Deliver: honest diagnosis of what blocks innovation today, the structure that creates real space (protected time, simple submission channel with guaranteed response timeline), treating error as part of the process, incentive that isn't just symbolic recognition, and result measurement (ideas that became tests, tests that became real products). Objective: innovation as a daily encouraged behavior — not a wall slogan.
