QUESTION 17 James Johnson Factory Scenario Use the information given below for all questions about this scenario. James Johnson (also known as ) has started a factory to build electrical vehicle (EV) charging adaptors that allow an EV to be plugged inta charging stations of different companies. He has estimated that the factory should produce 90 units of the product per hour to be able to meet customer demand.The work elements that are involved in production are l isted in the table below along with the time taken, in seconds, by each work element. Work Immediate Predecessors None Time (s) Element 30 42 25 16 32 28 A D, C, B E,F G F 41 H 17 What is the theoretical minimum number of workstations? (Enter a whole number as your answer as fractional workstations are not practical.)

![**Question 18**
**James Johnson Factory Scenario**
Suppose that a line with 6 work stations is set up (with the work elements divided across the work stations as taught in chapter 05). What is the efficiency of this line? Enter your answer on the percentage scale (0 to 100) rounded to 2 decimal places. Do not type in the % sign. For example, if you obtained 67.13%, you will only enter 67.13.
