- The following is a list of six control plans from this chapter or from Chapter 9 and Chapter 10. These are followed by a list of five statements describing either the achievement of a control goal (i.e., a system success) or a system deficiency (i.e., a system failure). Match the five control goals or system deficiencies with a control plan that would best achieve the desired goal or prevent the system deficiency. A letter may be used only once, with one letter left over. Control Plans Review shipped not billed sales orders Turnaround documents Deposit slip file Procedures for rejected inputs Computer agreement of batch totals Document design Control Goals or System Deficiencies The shipping clerk could not read the quantity picked that had been written on the picking ticket by the warehouse clerks.
