Notes
  • Spare parts generate high sales margins and improve customer loyalty by extending the useful life of base products. Forecasting and managing the spare-parts business is challenging, however, due in no small measure to short life cycles and long support life for the base products. At Hewlett-Packard, the Replacement Parts Business (RPB) was challenged by shortages that drove customers to competing parts suppliers. To deal with this threat, an HP team refined the company’s forecasting methodology. This paper describes the business issues involved and the forecasting processes developed. Of particular methodological interest is their approach to (a) choosing between monthly and quarterly forecasts, (b) adjusting the historical data for price/​promotion effects, and (c) combining regression and time-series forecasts.
