Step-by-step explanation:
The most suitable sales forecasting technique for estimating sales of a new product would generally be market tests. Market tests involve introducing the new product to a small, representative sample of the target market and recording actual sales. This technique provides more accurate data about consumer preferences and behaviors compared to other techniques.
For example, if a company is launching a new smartphone, they might conduct market tests by releasing a limited number of devices in specific locations and tracking sales. This would allow the company to gather real-world data on consumer demand and make more informed sales forecasts.
