Lead Time Sound Tek Inc. manufactures electronic stereo equipment. The manufacturing process includes printed circuit (PC) board assembly, nal assembly, testing, and shipping. In the PC board assembly operation, a number of individuals are responsible for assembling electronic components into printed circuit boards. Each operator is responsible for solder'lng 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 t'lme. After each batch is completed, the operator moves the assembled boards to the final assembly area. This move takes 12 minutes to complete. The final assembly for each stereo unit requires 20 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 507unit batch is tested one at a time. Each test requires 8 minutes. The completed batch, after all testing, is sent to shipping for packaging and nal 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 6 mlnutes per unit. 1. Determine the amount of valueadded and nonvalueadded lead time and the valueadded ratio in this process for an average stereo unit 'ln a batch of 50 unlts. Categorize the nonevalueeadded time into wait and move time. Round the percentage to one decimal place. \\I min. Valueeadded lead time Nonvalue-added lead time: Wait time lead time m'ln.
