Have good controls so that you are not exposed to the dishonesty of others.

1.Investigate and let people know you are going to investigate. 2. Remember that there is no sense in having laws unless you have policemen (auditors). 3. Beware of rubber-stamping. 4. Recognize that people who make purchases on your behalf probably will not spend your money wisely. 5. Use “public hangings” to deter bad behavior.
