Which of the following is NOT a method for determining when to do a cycle count?

Requesting customer feedback is not a recognized method for determining when to conduct a cycle count. Cycle counting is typically aimed at ensuring inventory accuracy and managing stock levels effectively, and it relies on more operational measures rather than subjective customer input.

Data entry (drop off) is an essential process because it provides real-time updates on stock levels, helping to identify discrepancies. Visual inspection of the shelf allows for immediate detection of stock issues or discrepancies that may warrant a cycle count. Reviewing reports gives insight into inventory turnover rates and highlight patterns in stock discrepancies, which can signal when a cycle count may be necessary. Therefore, these methods are all integral to the inventory management process, while customer feedback does not directly relate to the inventory counting practices.
