Question 4 (10 points) Mando Mobiles is putting together door sensor kits for their new vehicle. Production supervisor, Armando Valdez, has instructed the work unit to prepare sensor kits for the next batch of vehicles. Each sensor kit should contain the following components: 1 circuit board 1 LED 1 Integrated Circuit Chip (IC) Members of the work unit are responsible for preparing the sensor kits and they plan to use the following process to do the job: Step 1 (13 seconds - 10 workers): Test the circuit board: pass the bag to Step 2. Step 2 (20 seconds -15 workers): Attach IC to circuit board; pass to Step 3. Step 3 (8 seconds - 5 worker): Attach LED to circuit board: pass to Step 4. Step 4 (10 seconds - 8 workers): Test completed sensor, pass to Step 5. Step 5 (21 seconds - 27 workers): Package completed sensor kit. 1 2 3 4. What is the bottleneck in this process? What is the resource utilization of each step? What is the average labor utilization of the work members? Assume the work members are paid $16 per hour. What is the cost of direct labor for the sensor kit? To maintain the current capacity and maximize efficiency, would you change the staffing of personnel for this process? If yes, what would be the changes of staffing for each step? 5. Question 4 (10 points) Mando Mobiles is putting together door sensor kits for their new vehicle.
