How do operations managers ensure quality and efficiency during the transformation process of inputs into outputs?

Question $36$ options:

They shift from material$-$requirements planning $($MRP$)$ to just$-$in$-$time $($JIT$)$ inventory management.

They take measurements at various points in the transformation process and compare them to established standards.

They always employ computer$-$assisted manufacturing $($CAM$)$ technologies to guide and control the transformation processes.

They ensure that their products never use the modular design of transforming because this process increases the cost of labor.
