#6 KEY COMMODITIES IDENTIFIED
Then for each process, the technical experts identify the commodities (equipment, material, know how) which are key to the process being able to produce the identified end item at the state-of-the-art level for the End Item parameters identified. The key commodities listed are those which comprise the standard production line and not the commodities which comprise a production line which produces a commodity which is part of a standard production line. In most cases the key commodities listed should be equipment. The logic terms between key commodities [sic] are also stated.
