LightEdge Technologies would like to put in place an assembly line in its Mexican facility that puts together Internet servers. The tasks needed to accomplish this, including times and predecessor relationships,

Draw a precedence diagram for the tasks. Suppose the task time is $240$ seconds $($four minutes$).$ What is the theoretical minimum number of workstations? notes, linkages to videos and other documents, and online testing capabilities. From a services perspective, how are online courses positioned vis$--$vis large lecture classes? What are the advantages and disadvantages of online courses? What are the managerial challenges?

Develop workstation assignments using the "largest eligible task" rule $($i$.$e$.,$ assign the largest task that will fit into the workstation without exceeding the task time$).$

How many workstations does your solution require? What is the cycle time for the line? What is idle time?
