Which of the following is true regarding the steps to reducing setup times?

A) The first step involves performing as much setup preparation as possible while the process/machine is operating.
B) The cycle of steps is repeated until setup time is reduced to under a minute.
C) The standardization of both tooling and work procedures is advantageous to setup time reduction.
D) Improved material handling and move material closer are done before operator training.
E) All of the above are true.

Each of the statements provided is true regarding the steps to reducing setup times. A) Performing setup preparation while the machine is operating is a key strategy in reducing downtime. B) The goal of setup time reduction often involves iterative cycles of improvement, sometimes aiming for the "one-minute exchange of dies" (SMED). C) Standardization of tooling and procedures helps in reducing variability and inefficiency, thus reducing setup times. D) Improving material handling and reorganizing materials to be closer to the point of use are foundational steps that often precede more complex changes such as operator training.
