Which of the following describes a characteristic of automation in manufacturing?

Improving consistency in production is a hallmark characteristic of automation in manufacturing. This consistency arises because automated processes are programmed to perform tasks with precision, reducing the chances of human error that can lead to variability in product quality. When machines handle repetitive tasks, they can maintain the same performance level across numerous production cycles, resulting in products that meet specified standards more reliably.

In contrast, the other options present misconceptions about automation. While automation can change the nature of jobs, it does not completely eliminate human jobs; rather, it often shifts the workforce to more skilled positions. Additionally, automation may not necessarily reduce equipment costs initially, as the setup and purchase of advanced machinery can be significant investments. Lastly, automation typically accelerates processes rather than slows them down, enhancing productivity and efficiency in manufacturing operations.
