Market Research or Marketing Research is the process of determining the viability of a product or service in a given market, conducted directly with potential consumers. This can be done through surveys, product testing, and focus groups; and this process is a critical component in the R&D of a new product or service.
By gathering, recording and analyzing qualitative and quantitate data we can identify and assess challenges and determine opportunities, and overview the strengths and weaknesses of the product or service.
Market Research is very important even if you are already successful. You will simply fall behind if you stop evolving.
