7-- Assume the demand is 30 students per hour . At the moment , the system is FULL. How long will it take to process 20 students ?

8--- Assume the demand is 30 students per hour. Assume the system is EMPTY . How long will it take to process 20 students ?

9--Assuming UNLIMITED demand and you doubled the number of staff at the BOTTLENECK Which STEP now becomes the new BOTTLENECK ?

10--Assume the demand is 10 students per hour. What is the cycle time ?
