Where do problems get fixed?

You can have circular loops that promote and foster error or you can have circular loops that improve process and efficiency. In a loop where one group, department, or person is creating a problem but they are shielded from the clean up change might be unlikely. However, if you balance responsibilities and accountability in such a way that problems are apparant and the instigator is involved, you'll likely to see organic improvement.

Structure your org to maximize accountable so that problems can be solved where they originate.
