and encourage enterprises to break through the traditional relationship model between enterprises and customers and propose new products. Lethe (2006) confirms the relationship between enterprises and customers through the observation of the benchmarking customer research, finding a positive correlation to innovation. He posits that good relations between enterprises and customers results in more efficient benchmarking, identifying new potential products, reduce the cost of new product development and increase market acceptance of products.
