For Japanese companies operating in Thailand and wishing to promote indigenous enterprises, the fostering of entrepreneurial mind in Thai businessmen is essential in order to realize QCDS (quality, cost, delivery, service), a typical goal of Japanese firms. This is perhaps more important than obtaining manufacturing technology and updating production machinery and equipment. The latter two can be achieved by increasing human resources and raising funds. By contrast, business mentality is deeply rooted in the national character of the Thai people. To change this, fundamental measures, such as a radical reform of the educational system, is required.
