In this particular scenario, you are taking the perspective of a contractor who has identified a possible instance of fraud. Respond to at least one of the questions below. There is no right or wrong answers.

You are a mid-level Contracts Administrator in the ABC, Inc. contracts department. You are responsible for approving invoices being submitted to the Government. You notice on this month's invoice that some charges appear that don't belong to the contract; perhaps it is equipment rental or the assignment of a particular engineer. You go to your boss and he says that he'll take care of correcting it. A few months later, you are reviewing some billing information and you notice that the invoice that you questioned has been paid by the Government. You check only to learn that the invoice, which you suspected was in error, was submitted and paid.

• What can the contractor do to avoid these problems?
