Given the work element times shown in the following table, what is the theoretical minimum number of workstations? Round your answer UP to the nearest whole number.

Using the information presented above. Set up a table with columns titled "Workstations", "Candidates", "Choice", "Cumulative Time", and "Idle Time". Assign work elements into workstations, one element at a time using the longest-work-element-time rule, while keeping an eye on the "idle time" and the precedence relationships in the diagram.

Using the information presented above. Calculate the efficiency based on the "actual number of workstations" you'd obtain. Show your work.
