Case Study: Sunshine Fruity Pty Ltd starts juice bar business. It sells fruit and vegetable juices. Staff take orders from customers, serve the produced fresh juices to the customers and collect the money from the customers. Staff produce juices daily in the store or bottled and stored the produced juices in advance of customer orders based on anticipated demand. Staff purchase fruits and vegetables, and make payments. Each day staff take out the fruits and vegetables needed for making juices. These fruits and vegetables can be perishable or non-perishable according to their shelf life. For example, fresh vegetables would be perishable in two days where some fruits would be considered to be non-perishable in two days. Staff monitor which fruits and vegetables are running low every two or three days and draw up a list of that which needs to be ordered, based on re-order quantities and re-order levels. Sometimes they may need to readjust their re-order levels. A number of suppliers are used, and there is more than one possible supplier for each type of fruits and vegetables. Most of the ordering is done via the telephone. When deliveries are received, staff check the attached delivery note against the goods received.
