The BWE measures vary greatly among different forecasting techniques for the same auto type. 
Since the replenishment policy is fixed , the BWE measures show the effect of forecasting methods used and may suggest a good method for order management.
Moreover, BWE measures from a few specific forecasting methods are consistently greater than those from others. Likewise, the ANOVA results further confirm the variation of BWEs with the choice of the forecasting method. 
These observations mean that if a less-desired forecasting technique is used, the BWE problem can be multiple times more serious than that from an alternative forecasting technique. 
Namely , if a firm can apply right forecasting technique for demand forecasting, it helps to control the problem of the BWE.
