Constanza is the father of demand-flow manufacturing. Demand flow manufacturing does away with schedules and forecasts, inventories of finished goods and the warehouses in which the goods were stored. Demand-flow manufacturing substitutes raw in progress goods, in which a cushion of varied materials, are constantly kept on hand to meet the customers changing demands. Under demand-flow manufacturing, goods move directly from the assembly line into waiting trucks to be delivered to the customers. This helps develop a supportive relationship between the two parties.
Plant layout is a necessity.
Technology should be grouped in a way that enables for little movement in the production process from on station to the next. Machinery should be easily changeable and easily moved to meet production demands. Accurate scheduling is a necessity. There should be no deviation form the schedules set by the production facility. Supplier should be informed of the schedules so they are aware of the time constraints and are able to work with the production facility to accommodate their needs.
