How might a firm find out about whether there is a need for a new product?

Hi, hahaqaz!

One way would be to take a poll of the needs of potential customers by making phone calls to them.

Another way would be to send out survey sheets.

Are you asking the question because of a class that you're taking or because you run some kind of business or are a part of a business, please?

Thanks!

Basic defined marketing along with demographics of the area, financial earnings, etc.
