Ledd Time Sound Tek inc. manufactures electronic stereo equipment. The manufacturing process includes printed circuit (PC) board assembly, final assembly, testing, and shipging. In the PC board assembly operation, a number of individuals are responsible for assembling electronic componerts into printed circuit boards. Each operator is responsible for soldering components according to a given set of instructions. Operators work on batches of 50 printed circuit boards. Each board requires 4 minutes of board assembly time, After each batch is completed, the operator moves the assembled boards to the final assembly afea. This move takes 9 minutes to complete. The final assembly for each stereo unit requires 20 minutes and is aloo 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. equigment must be set up for the particular sterco model. The test setup requires 30 minutes. The units wait while the sebup is performed, In the final test, the 50 -unit batch is tested one at a time, Each test requires 7 minutes. The completed batch, after all testing, is sent to shipging for packisging 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 labeling requires 7 minutes per unit. 1. Determine the amount of value-added and non-walue-added lead time and the walue-adsed ratio in this process for ant average stereo unit in a batch of 50 units. Categorize the non-value-added bime into wait and move time. Round the percentage to one decimal place, 2. Move time in this process could best be reduced by: a. Doing nothing. b. Changing the layout from a process orientation to a product orientation. c. Increasing batch sizes. d. Eliminating the testing step. e. Hiring more workers
