“Availability and affordability of the product were considered to be the key to the success of a firm”. Identify and explain the concept of marketing given in the above statement

Dear Student,
The concept is Production concept.
It is one of the Marketing Management Philosophies. This concept was based on the assumption that customers are primarily interested in products which are accessible and affordable. It  was introduced at a time when business was focused mainly on production and at that time demand was more than supply. It says that a business will be able to lower average production costs by producing more quantity or mass production of goods.
Regards.
