Why does organizational culture impact fail?

The most common reason organizational culture impact fails: Agreeing that 'systems matter' while still blaming individuals when something goes wrong in your own organization. The test isn't whether you can cite Deming in a meeting. It's whether, when a colleague underperforms, your first question is 'What about this system made this outcome likely?' rather than 'What's wrong with this person?'

The fix: Pick one behavior in your organization that frustrates you — missed deadlines, siloed communication, risk aversion, whatever recurs despite everyone agreeing it's a problem. Now answer: What does the system reward? What does it punish? What does it measure? Map the actual incentive structure, not the stated values. You'll almost certainly find the frustrating behavior is a rational response to the system as designed.

The underlying principle is straightforward: The structures and incentives of an organization determine individual action more than personality does.
