Question - Wares king supplies custom-fitted curtains and blinds to retail customers. It has recently expanded to offer a wide variety of home decorating products through its six stores across the state. After some initial problems with stock control it installed a new automated inventory system in April this year. The system replaced another automated system that had been modified so often over the years that the auditor had advised Wares's management that they did not regard it as reliable. That is, the auditor was unable to rely on the old system sufficiently to assess control risk for inventory as anything less than high.

Required -

a) Explain the normal process an auditor would expect to find in the client's systems governing changes to computer programs. Why is an auditor concerned about program changes?

b) Wares kings' financial year-end is 31 December. Does the auditor need to obtain evidence about the performance of the inventory control system from every month in the year or from a sample of months? Explain.

c) If the auditor conducts test of the inventory controls at an interim date, is it appropriate to conclude that the controls also relate to the end of period date? Why?
