With fierce competition in traditional manufacturing industry, it is urgent to find an effective way to gain competitive edge for enterprises to win market share. In this paper, we introduce novel ideas on new product design and customized product marketing in order to improve enterprises competitiveness by discovering business insights from multidimensional data, including product/customer profiles, sales data, Voice of Customers (VoC), and so on. A detailed case study on one famous home appliance manufacturer in China is given. Especially, VoC is introduced into new product design and the statistical model - Analysis on Variance (ANOVA) is applied to conduct in-depth data analysis. © 2013 IEEE.
