Jane produces custom greeting cards using six distinct work elements. She would like to produce 10 cards in each 8-hour card-making session. Figure 1 details each work element and its associated durations in minutes as well as their precedence relationships. a. What cycle time is required to satisfy the required output rate? b. What is the theoretical minimum number of workstations required? c. If Jane identifies a five-station solution, what is the associated efficiency and balance delay? d. If the cycle time increased by 100 percent, would the theoretical minimum number of workstations also increase by 100 percent? (10)
