Syntex was a company carrying on business in cosmetics and perfumes. It was not following the marketing concept and was catering to a target market which was using its products. In other words, it only concentrated on what it would make, and did not bother about changes in preferences of its target market.
It was later joined by Mr. George, a marketing graduate who advised the company regarding the changing consumer preferences, and the changes that were necessary to be incorporated in the product. He emphasised upon the income factors, and social factors only. He modernised the products to a great extent, and invested about 30 lakhs on new packing, etc. Even after six months of these changes brought about by him, the company did not seem to have proportionate increase in sales. The assistant manager and the product manager were not very happy with the changes, and thought that although an effort has been made in the right direction, some important factors concerning consumer behaviour had been neglected.

As a Marketing Manager of the company, design a consumer behaviour research methodology plan to identify the crucial factors concerning consumer behaviour.
