Sustainability Report 2007

In order to ensure swift response and full support for our customers in the event of a defective product arising, we have installed a Information Management System for Quality Claim (RAINBOW System) and a Traceability System that link together all of our global production bases.

RAINBOW Diagnosis

We administer our quality control system and examine the management status of our production bases in order to improve the level of quality and to prevent the occurrence of quality defects in all of the plants we control both at home and overseas.

The diagnostic team organized inside the company carries out examinations production line by production line in all of our domestic and overseas production bases in accordance with a set schedule at the beginning of each term. If a problem is diagnosed, the company concerned must judge ways to solve the problem. Follow-up examinations for the purpose of verification and guidance are then made of the details of the determined activities and the results they yield.

In addition to this, once the diagnostic process has been completed, training programs and other activities are held to improve the skills of the workers in order to prevent further quality problems.
