Quantity Adjust

ProcBox adjusts the user provided historical quantity to the current estimated procurement quantity.  ProcBox allows the user to select a quantity adjustment value to account for bulk discounts (or economies of scale and economic order quantities).  ProcBox adjusts the historical procurement costs to current year procurement by the user selected index.  The quantity adjustment value follows the learning curve values.   The following guidelines from “Cost Estimator’s Reference Manual – 2nd Edition” by Rodney Stewart can be used:

• Raw materials 93-96%

• Purchased Parts 85-88%
