The strong form of this claim: even a naturally bold product leader with real judgment will fail in an org that hasn't set up Three-Level Decision Framework (Strategic / Product / Execution) — i.e., hasn't clarified which decisions sit at the strategic, product, and execution altitudes and who owns each. This reverses the usual 'develop the individual' framing of product leadership advice: the fix for a struggling product leader is often structural, not personal.
