The schedule design phase examines the following issues:

■ How much to produce? (lot sizing)
■ When to produce? (production scheduling)
■ How long to produce? (market forecasts)

The determination of the outputs of a system seems very straightforward at first
examination, as it should be defined in the goal. In the television example, it is 30,000
televisions per year. This is only a partial answer as there will also be unintended out-
puts, which includes waste and by-products, that must also be considered. Waste
