A demand forecast is the prediction of what will happen to your COMPANY's EXISTING product sales. It would be best to determine the demand forecast using a multi-functional approach. The INPUTS from sales and MARKETING, finance, and production should be considered. The final demand forecast is the consensus of all participating managers. You MAY also want to put up a Sales and Operations Planning group composed of representatives from the different departments that will be tasked to prepare the demand forecast.
