We propose a concept model and a function model of Internet/Extranet/Intranet Based Quality Information System (IEI-QIS)， which absolutely integrates the quality information of the enterprise， customers and suppliers and serves as powerful tools to benefit quality management of modern extended enterprises. The browser/server based and three-tier architecture of the system is also investigated.
