ISounds Inci manufactures electronic stereo equipment. The manufacturing process includes printed circuit (PC) board assembly, final assembly, testing, and shipping. In the PC board assembly opetation, a number of individuals are responsible for assembling electronic components into printed circult boards. Each operator is responsible for soldering components according to. a given set af instructions. Operators work on batches of 50 printed circult boards. Each board requires 4 minutes of board assembly time, After each batch is completed, the operator moves the assiembled boards to the final assembly area. This move takes 12 minutes to complete. The final assembly for each-stereo unit requires 21 minutes and is also done in batches of 50 units. A batch of 50 stereos is moved into the test building, which is across the street. The move takes 20 minutes. Before conducting the test, the test equipment must be set up for the particular stereo model. The test setup requires 30 minutes. The units wait while the setup is performed. In the final test, the 50 -unit batch is tested ore at a time. Each test requires 9 minutes. The completed batch, after all testing, is sent to shipping for packaging and final shipment to customers. A complete batch of 50 units is sent from testing to shipping. The Shipping Department is located next to testing. Thus, there is no move time between these two operations. Packaging and tabeling requires 9 minutes per unit. Required: 1. Determine the amount of value-added and non-value-added iead time and the value-added fitho in this proceis for an average stereo unit in a batch of 50 units. Categorize the non-value-added time into wait and move time. Round the percentage to one decimal ptace. 1. Determine the ampurt of value-added and fon-value-udded lebd time and the value-added ratio in this procecs for an arverage iter eo unit in a batch of So units. Categorize the non-valun-added time inte wait and move time. Round the percentage to one decimal place. 2. Move time in this process could bent be reduced by: a. Ooing nothing. b. Changing the taygut from a'process orientation to a product ontentation. c. increasing Datch sizes. d. Eliminating the testing strp. e. Hiring mare workers
