What is a basic purpose of marketing investigation?

Dear Mr. Farrukh,

I think that the term ''marketing investigation'' is quite appropriate and widely used-simply type it in some browser to see how many results you will get using this term.

Anyway, thank you for answering my question.

The basic purpose of marketing investigation or research is only to get answer where we stand in the market wit our product or to make the strategy accordingly.

Basic purpose to identify market trends, changes, evaluation of USP  and competitive edge. 

Marketing investigation or marketing research is "the process or set of processes that links the consumers, customers, and end users to the marketer through information — information used to identify and define marketing opportunities and problems; generate, refine, and evaluate marketing actions; monitor marketing performance; and improve understanding.

basic purpose of marketing investigation is used to identify the need of the customer and produce the product as per customer specification to increase the sales and grab the market

In my opinion, the more appropriate question would be:

"What is the basic purpose of Marketing Research?"

Answer: The basic purpose is to identify the right "Marketing Mix" for a product or a service.
