Accounting and Finance for Managers interview questions

I am gonna interview a manager for my final project.

1. For the subject firm, identify how it currently assigns costs to its products or services, and to its customers. A flowchart may be a good way to represent the present system.

1. Identify any weaknesses in this system and indicate how they might lead to distorted data. How might these distorted data lead to poor management decisions?

I need to ask some questions for this manager so that I can finish my interview.

Please help make up some questions in the interview. Questions I need to ask will be related to  the above requirements, not some general questions.
