The fewer the inputs required to produce a given output, the higher the efficiency of a production system.  A measure of the organization’s efficiency in turning all of its inputs into outputs is:  A measure of a single input (such as labor) to total output (i.e., partial productivity):

Example: mass production systems where workers are stationary and a belt moves work to them.Example: mass production systems where workers are stationary and a belt moves work to them.

The more often products to be built change, the higher setup costs become.The more often products to be built change, the higher setup costs become.  Flexible manufacturing reduces setup costs by reducing the time required to reset the production line for a different product by: Using easily replaced manufacturing equipment.Using easily replaced manufacturing equipment.
