Each operation can have a number of different times specified so that the time taken to setup the manufacturing environment, machinery and work centers to perform the operation and time to teardown the environment down can be accurately recorded and accounted for.

The different times include:

Set-up time indicates the time taken to ready a specific machine, process or work center for use. No usable items are produced during the setup period. It forms part of an operations elapsed time.
Startup time is used to indicate the time taken to gradually bring the specific machine, line or work center up to full production speed while producing usable product. It forms part of an operations elapsed time.
Startup quantity is used to indicate the quantity of product manufactured during the start up period and is deducted from the actual quantity to be manufactured when the run time is calculated.
Teardown time is used to indicate the time taken to close down the specific machine, line, or work center used in the operation after production is complete. It forms part of the elapsed time. Typically, no usable items are produced during the teardown period.
Wait time is used to indicate the amount of time between the end of the current operation and the availability of the product to be moved to the next work center. This forms part of elapsed time. Wait time is not included in the calculation of capacity required or in the costing calculations.
