A warehouse takes orders from 8:00 AM to 4:00 PM. The manager wants to analyze the process and has provided the below process flow diagram. There are three steps required to ship a customer order. The first step is to take the order from a customer. The second step is to pick the order for the customer, and then they have to pack the order ready for shipping. Wally promises that every order placed today gets shipped tomorrow. That means that the picking and packing operations must finish all orders before they go home.
