Final answer:
The correct term to fill the blank is 'operational goal' as it pertains to the daily efficiency and productivity improvements a line supervisor like Aliya would aim to implement.
Step-by-step explanation:
Aliya is a line supervisor in a denim apparel factory and has set a goal to reduce the time she spends training new workers. The most appropriate option to fill in the blank is an operational goal. This type of goal is focused on the daily operations of a business and aims to increase efficiency and productivity.
An operational goal in Aliya's context would likely involve implementing training processes that are more streamlined and that can be easily replicated, leading to a mechanized work environment where the focus is on producing identical products in every location efficiently.
