Setup/Cleanup versus Scheduled Production Time
This chapter considers the gap between theoretical output and actual output. It describes the use of standard procedures and work allowances to reduce theoretical output to a planned level. These serve as the basis for performance metrics (e.g., time to first quality product). Monitoring operational experience against plans resulting from scheduled production time and standard procedures and work allowances can indicate equipment operating beyond its capability and requiring frequent minor stoppages for resetting process conditions. Process control studies establish appropriate limits and conditions for predictable and sustainable equipment operation that will produce quality product.
