Abstract
In the report of Tsuda (1966) a "2-storied quality chart" and a "Parallel flow quality chart" were proposed. In this report 2 cases, one from the product planning and debelopment process which was focused on the European market and another from the product introduction preparation process into the Japanese market, will be reported after the Nissan Primera Project on which basis the above 2 models were debeloped. By comparing these models with those actual cases, the author expects that readers will more easily understand these models including the concepts behind them and that these models will be verified as good development tools.
