2 Delphi method The “Delphi method” is a technique for making predictions about events that may occur in the future. It is used in activities such as planning technology development strategies. In this method, independent opinions from multiple experts are collected and reviewed. The feedback is returned and the experts make adjustments as necessary for further review. This process is repeated over and over until the opinions of the experts can be statistically aggregated to produce a consensus. As a result, highly accurate forecasts regarding unknown issues can be obtained. Production systems Chapter 2 3 Business strategy The question of how to design a production process is an important element of business strategy management. Production processes are designed by considering requirements such as the characteristics of the product being produced, cost, quality, and delivery date. The production system must be able to be redesigned to suit requirements such as high-mix low-volume production, production with quick delivery time, inventory reduction, etc. The main production systems are summarized below. ●Cell production system A “cell production system” is a production system used in assembly processes in which between one and several workers are in charge of the entire process from component installation to assembly, processing, and inspection. Its name was derived from work that arranges components and equipment into cells. The advantage of the cell production system is that it is possible to change the product being assembled simply by changing the workers, components, or work sequence, which affords flexibility in the production of a large variety of products. ●Line production system A “line production system” is a production system in which dedicated lines are established using conveyor belts or similar contraptions. Numerous workers assemble the respective components that they are in charge of and perform the same work repeatedly. The advantage of the line production system is high productivity as it allows a specific product to be mass-produced. ●BTO (Build To Order) “BTO” is a production system that manufactures products after receiving an order from the customer. Components are assembled and shipped according to customer orders, which reduces the risk of having surplus stock. This production system is used by many major computer manufacturers as well as other manufacturers that mass-produce products such as automobiles. Reference BTO Abbreviation for “Build To Order.” 76
