What do we do if the management deviate from policies very often?

It works in a very professional company. But do you think it works well with a company which is not so professional?

If the management often deviates from policies, then the next step that should be taken by Policy Makers is to set a forum and discuss the reasons of these deviations. Open discussion often leads to change in the policies that are suitable for the management as well as the managed resources.
