Q287 Angela Bauer was a training supervisor for claims processing at John Healthcare. As a standard part of claim processing training program, Angela created fictitious claims for use by trainees. These fictitious claims were then sent to the accounts payable department. After the training claims had been processed, she was to notify accounts payable of all fictitious claims, so that they would not be paid. However she did not inform accounts payable about every fictitious claim. She created some fictitious claims for entities that she controlled and she let accounts payable pay her.

Explain the missing control with reference to the above case.
