Question

Manner Corporation is trying to determine how long it takes for one product to pass through the production process. The following information was gathered regarding how many days the product spent in various production activities:..... Activity = Inspection...Number of days = 5... Activity = Storage ... Number of days = 6..... Activity = Assembly... Number of days = 3... Activity = Handling... Number of days = 2... Activity = Painting... Number of days = 3 ..... Activity = Packaging..... Number of days = 1 ...... a. Which of the above activities is value added?..... b. What is Manner

Explanation / Answer

"Inspection" is value added. cycle time 20 days. Manufacturing efficiency determines how well a factory operates in production. To avoid wasting money, all processes in manufacturing must be as efficient as possible. Calculating a numerical value to the efficiency helps to identify if improvements to the production process need to be made. Keeping careful records facilitates the calculations. 1 Determine the time it takes to complete each piece of an order from the point of order until delivery. Record this as the total production time. In this time are included inspection time, the time during which the product is moved and downtime waiting between steps to continue the manufacturing process. Do not include waiting time before the order process actually begins. 2 Separate out the time actually spent manufacturing the product, also called the value-added time. Look for the length of time the product spends in the factory line where the actual construction occurs. Do not include other parts of the order and delivery process in this time. 3 Calculate the manufacturing efficiency. Divide the amount of total manufacturing time by the value-added time. For instance, a car that is delivered 15 days from when it is ordered and production is initiated, and that spends three days on the manufacturing line would have manufacturing efficiency of 3/15 = .2. 4 Convert the answer from step 3 to a percentage by multiplying it by 100. For instance, .2 x 100 = 20 percent. Use this percentage as the manufacturing efficiency: A lower number means less efficiency and indicates time wasted in the manufacturing process. 5 Use the information to plan how to improve manufacturing to create a more efficient process. Reduce waiting, queuing and inspection times to help better the efficiency rate.
