Smartphones are made on a 40-step assembly process. All 40 steps are connectedthrough a conveyor belt and all of the 40 steps must work at the same rate even if someof them have more capacity than others. Is this process a machine-paced process or aworker-paced process?a. Machine-pacedb. Worker-paced
ene is working with the operations manager to determine what the standard labor cost is for a spice chest. He has watched the process from start to finish and taken detailed notes on what each employee does. The first employee selects and mills the wood, so it is smooth on all four sides. This takes the employee 1 hour(s) for each chest. The next employee takes the wood and cuts it to the proper size. This takes 43 minutes. The next employee assembles and sands the chest. Assembly takes 3 hour(s). The chest then goes to the finishing department. It takes 3 hour(s) to finish the chest. All employees are cross-trained so they are all paid the same amount per hour, $17.62.
What is the standard cost per chest for labor? Round to the nearest penny, two decimal places.
Consider the example of the three-step process. The first step takes 20 minutes/unit, the second step takes 10 minutes/unit, and the third step takes 15 minutes/unit. Eachstep is staffed by one worker. What is the labor content of the process?

- The higher levels of the work breakdown structure (WBS) represent increasing amounts of detail while the lower levels represent broad categories of activities. Question 18 options: True Falsearrow_forwardSmooth Chin Device Company The Smooth Chin Device Company is a manufacturer of high--end electric razors. These razors are produced using a machine--paced process. For each razor, a tray with components enters the process at the beginning of a conveyor belt. The tray then passes through the six steps (consisting of various tasks) explained in the table below. Workers perform the assembly operations on the moving tray. The last step consists of an inspection of the then fully assembled razor. The activity times of the process are as follows: Station Tasks A Preparation 1. Lay out chassis [12 sec] 2. Lay out screws [15 sec] 3. Lay out all other components [17 sec] Total time for A: 44 sec B Assembly 4. Perform task AS1 [10 sec] 5. Perform task AS2 [10 sec] 6.

- Recently, some operations management experts have begun insisting that simply maximizing process velocity, which actually means minimizing the time it takes to process something through the system, is the single most important measure for improving a process. Can you think of a situation in which this might not be true?arrow_forwardUnder Taylor's differential piece rate scheme, if a worker fails to complete the task within the standard time, then he is paid: 175% of the piece work rate 125% of the piece work rate 83% of the piece work rate 67% of the piece work rate Pls answer fast i give up vote plz select correct option without explanationarrow_forwardSmooth Chin Device Company The Smooth Chin Device Company is a manufacturer of high-end electric razors.

The tray then passes through the six steps (consisting of various tasks) explained in the table below. Workers perform the assembly operations on the moving tray. The last step consists of an inspection of the then fully assembled razor. The activity times of the process are as follows: There are six workers, one at each of the six stations (A-F). They begin their workday at 8:00 a.m. and work steadily until 4:00 pm. (They are replaced with other workers for breaks and lunches, but the production is not slowed or stopped during these times.) Their hourly wage rate is $25 per hour. You can assume unlimited demand. What is the process capacity (you can ignore any start-up or empty system effects), in razors/hour?arrow_forward

- Cubway, the sandwich shop, is run by Jim, Tim and Kim. When a customer arrives, Jim spends 5 minutes taking order from the customer. After this, Tim prepares bread and Kim prepares filling for the order. These activities are performed in parallel, and take 6 and 12 minutes respectively. Jim then assembles the bread and filling, which takes 4 minutes of his time. Finally, Tim spends 1 minutes in delivering the order and taking payment. What is maximum number of sandwiches Cubway can make per hour? (In other words, what is the capacity of the process in sandwiches per hour?)arrow_forwardStoryboarding may be used to develop a detailed process flowchart. Group of answer choices a. True b.
