Answer: All Apply except (A)
Explanation:
(A) Using a shorter time horizon - Product sales forecast can be made more accurate by using a longer time horizon. A forecast is an insight into future business turn out, not a rushed inquisition. The forecaster should be able to go into the future in steps; how will product purchase be in the short run, middle run and long run. That will help better in decision making for the production of the product.
(B) Aggregating to product families or location - Product sales forecast can be made more accurate by aggregating to product families or location. Product families will comprise complementary products, substitutes, and other related products. The market for these other products has to be considered in the forecast. Product location is the location where sales of that product is intended. The other products and then consumers in this location should be studied.
(C) Using multiple sources of information - Of course this is a good tactic for attaining solid information. Use already available data on the sales of the particular product and other related products; use questionnaire or one-on-one interview of customers; do market survey.
(D) Gathering data closer to the customer - Forecast can be made more accurate by gathering data closer to the customer. The main aim of production is to get a product to the final consumer. Infact, this is when production becomes complete. The customers are the main target. Gathering data close to them gives the near best set of data. You get to know their opinion on the product and the factors that will make them buy more or buy less of the product. They are to be well included in the forecast.
