In this paper, we propose a new evaluation method in the field of sign production, by applying the quantitative methods. We show the results of the evaluation items to extract the sign of improving customer satisfaction, introduces the concept of deviation signs, experiments were conducted practical method to evaluate the new sign. The method of experiment consists of the following two steps. First, we determine the evaluation items of the sign. Next, using the evaluation criteria, we evaluate the before and after improvement of signs of actual improvement. In order to improve customer satisfaction, we introduce the concept of deviation value of the sign here. Our proposal has given a new guideline for the production of the sign to determine the items that should be improved sign specifically, to compare values before and after improvement assessment improvement.
