Kellogg's conducted extensive market research to develop and launch a new product extension called Crunchy Nut Bites. The research involved 4 stages: 1) discovering new ideas through focus groups, 2) selecting the best idea through consumer ratings, 3) crafting the idea into products by testing recipes and packaging designs, and 4) forecasting sales through in-home product trials. This thorough process led to the successful launch of Crunchy Nut Bites in 2008, which achieved sales of £6.9 million in its first year, demonstrating the value of market research in new product development.
