Calculate Lead Time Williams Optical Inc. is considering a new lean product cell. The present manufacturing approach produces a product in four separate steps. The production batch sizes are 64 units. The process time for each step is as follows: Process Step 1 7 minutes Process Step 2 5 minutes Process Step 3 4 minutes Process Step 4 9 minutes The time required to move each batch between steps is 12 minutes. In addition, the time to move raw materials to Process Step 1 is also 12 minutes, and the time to move completed units from Process Step 4 to finished goods inventory is 12 minutes. The new lean layout will allow the company to reduce the batch sizes from 64 units to 4 units. The time required to move each batch between steps and the inventory locations will be reduced to 2 minutes. The processing time in each step will stay the same. Determine the value-added, non-value-added, and total lead times, and the value-added ratio under the present and proposed production approaches. If required, round percentages to one decimal place.

Use the following information for Exercises 5-44 through 5-46: The following six situations at Diviney Manufacturing Inc. are independent. a. A manual insertion process takes 30 minutes and 8 pounds of material to produce a product. Automating the insertion process requires 15 minutes of machine time and 7.5 pounds of material. The cost per labor hour is 12, the cost per machine hour is 8, and the cost per pound of materials is 10. b. With its original design, a gear requires 8 hours of setup time. By redesigning the gear so that the number of different grooves needed is reduced by 50%, the setup time is reduced by 75%. The cost per setup hour is 50. c. A product currently requires 6 moves. By redesigning the manufacturing layout, the number of moves can be reduced from 6 to 0. The cost per move is 20. d. Inspection time for a plant is 16,000 hours per year. The cost of inspection consists of salaries of 8 inspectors, totaling 320,000. Inspection also uses supplies costing 5 per inspection hour. The company eliminated most defective components by eliminating low-quality suppliers. The number of production errors was reduced dramatically by installing a system of statistical process control. Further quality improvements were realized by redesigning the products, making them easier to manufacture. The net effect was to achieve a close to zero-defect state and eliminate the need for any inspection activity. e. Each unit of a product requires 6 components. The average number of components is 6.5 due to component failure, requiring rework and extra components. Developing relations with the right suppliers and increasing the quality of the purchased component can reduce the average number of components to 6 components per unit. The cost per component is 500. f. A plant produces 100 different electronic products. Each product requires an average of 8 components that are purchased externally. The components are different for each part. By redesigning the products, it is possible to produce the 100 products so that they all have 4 components in common. This will reduce the demand for purchasing, receiving, and paying bills. Estimated savings from the reduced demand are 900,000 per year. 5-44 Nonvalue-Added Costs Refer to the information for Diviney Manufacturing on the previous page. Required: Estimate the nonvalue-added cost for each situation.
