Final answer:
Inventory with high value typically requires a signature from the Person in Charge due to the financial risks and need for accountability. Low-value inventory may not require a signature, and the perishability of the inventory is usually less relevant unless it is of high value or large volume.
Step-by-step explanation:
Whether an inventory requires a signature from the Person in Charge (PIC) can vary depending on company policy, the value of the items, and the risk associated with it. Generally, inventory with high value would almost always require a signature due to the inherent financial risks and the need for strict accountability. On the other hand, inventory with low value may not always require a signature, as the risks and potential losses are minimal. The type of inventory, whether it is perishable or non-perishable, typically does not dictate the need for a signature unless the perishable goods are of high value or significant volume, which can then increase the importance of tracking and accountability.
