A company has various rules for how payments to suppliers are to be authorized. Some payments are in response to an approved purchase order. For approved purchase orders under $5,000, the accounting clerk can immediately issue a check against that purchase order and sign the check. For approved purchase orders between $5,000 and $10,000, the accounting clerk can immediately issue a check but must additionally obtain a second signature. Payments for ap- proved purchase orders over $10,000 always require the approval of the accounting man- ager to issue the check as well as the signa- ture of two accounting clerks. Payments that are not covered by a purchase order that are under $5,000 must be approved by the ac- counting manager and a departmental man- ager who will absorb the cost of the payment into that department's budget. Such checks can be signed by a single accounting clerk. Payments that are not covered by a purchase order that are between $5,000 and $10,000 must be approved by the accounting manager and a departmental manager, and the check must have two signatures. Finally, payments exceeding $10,000 that are not covered by a purchase order must be approved by a de- partment manager, the accounting manager, and the chief financial officer. Such checks require two signatures. Use a decision table to represent the logic in this process. Write down any assumptions you have to make.
