Thedecision table above represents discount determination system used indetermining the points at which discounts are given to the customerson the purchases that they make. UMUC gives discounts to allcustomers with non-volume purchases, the decision table has takeninto consideration this category of customers and hence they aregiven discounts on purchase of specific single products. Thepercentage of discount for non-volume has not been specified as givenon the case study.
Thevolume discounts are being considered due to growth in volumepurchases, the discounts will be given depending on the volumesinvolved as shown in the decision table. Another important conditionthat has to be considered is the 2% additional value given after 30days of purchase, this value has to be added to the final purchasingvalue before determining the final discounts for the purchases. Theactions will be taken at various payment section as shown in thetable which include the quantity discounts, electronic invoicing, andthe electronic payment sections
