Abstract: | This study identifies factors that seem to influence a new firm's ability to accurately forecast new product sales. William Gartner and Robert Thomas present a conceptual model and develop hypotheses that specify antecedent factors prior to new product launch, such as the founder's expertise and the marketing research methods used, as well as environmental factors occurring after product launch, such as competitive factors and market volatility, that influence new product forecasting accuracy. The hypotheses were tested with data collected from a survey of 113 new U.S. software firms. Some tentative guidelines for improving sales forecast accuracy among new firms are offered. Directions for future research are discussed. |
