Final answer:
Human factors engineering is the operation management technique that aims to design the machine worker interface to increase production efficiency.
Step-by-step explanation:
The operation management technique that has a goal of designing the machine worker interface to increase production efficiency is Human factors engineering. Human factors engineering, also known as ergonomics, focuses on optimizing the interaction between people and machines to improve productivity and minimize physical and mental strain. By considering factors such as workstation design, equipment layout, and worker comfort, human factors engineering aims to enhance performance and reduce errors in the production process.
