Premium Ltd. manufactures cleaning detergents for supermarkets and public institutions. The company recently implemented
an integrated production and inventory system that automatically records movements of raw materials, work-in-progress and
finished goods. The system calculates standard material usage for each production batch and permits authorised adjustments
where wastage, spoilage or rework occurs.
You are the audit senior at Tumaini & Co., Certified Public Accountants, the external auditors of Premium Ltd. You have
been assigned to perform preliminary audit planning procedures and obtain an understanding of the new system before the
year-end audit.
During your preliminary review, you noted the following matters:
1. User access rights have not been reviewed since the system was implemented.
2. Production supervisors can initiate and approve adjustments for wastage and rework.
3. Exception reports identifying unusual production quantities and inventory adjustments are generated but are not
reviewed by management.
4. Finished goods may be released from the warehouse before dispatch documents are matched to approved customer
orders.
5. The internal audit department has not undertaken a post-implementation review of the system.
Required:
(a) Explain THREE control deficiencies in the production and inventory system and, for each deficiency, state its
possible effect on the financial statements of Premium Ltd.
(b) Recommend TWO information technology controls that Premium Ltd. should implement to ensure that access to the
system and changes to inventory data are properly restricted and monitored.
(c) Describe THREE tests of controls that Tumaini & Co. should perform to determine whether wastage and rework
adjustments are independently authorised, exception reports are reviewed and followed up, and finished goods are
dispatched only against approved customer orders.
(d) Explain TWO benefits that Premium Ltd. would obtain from a post-implementation review of the new production
and inventory system.
