Final answer:
Changing from 1 lot of 60 to 2 lots of 30 is expected to decrease lead time.
Step-by-step explanation:
When changing from 1 lot of 60 to 2 lots of 30, the lead time is expected to decrease. Lead time refers to the time it takes for a product to move through a process. By dividing the production into smaller lots, it reduces the time needed for each lot to be processed. In this case, dividing the lot into two smaller lots of 30 would result in a shorter lead time.
