Which factor is critical in maintaining lot control?

1. Daily audits of stock

2. Assigning unique batch numbers

3. Reducing lead times

4. Increasing workforce efficiency

The correct answer is: Assigning unique batch numbers

Assigning unique batch numbers is crucial in maintaining lot control because it enables a more precise tracking system for inventory. This practice allows organizations to identify and trace specific batches of products throughout the supply chain, facilitating better quality control and recall processes if necessary. Each batch can have its own history, including production dates, sourcing information, and quality assessments, which is vital for managing inventory effectively and ensuring compliance with regulations. In contrast, while daily audits of stock can help keep track of inventory levels, they do not specifically address the need for identifying and controlling lots in a systematic way. Reducing lead times and increasing workforce efficiency are important operational improvements, but they do not directly contribute to the management and control of specific product lots. Thus, assigning unique batch numbers stands out as the critical factor in maintaining lot control.
