Items 1 through 8 are selected questions typically found in questionnaires used by auditors to obtain an understanding of internal control in the inventory and warehousing cycle. In using the questionnaire for a client, a "yes" response to a question indicates a possible internal control, whereas a "no" indicates a potential deficiency.
