Verify the correctness of manufacturing procedures and devices, production
stability and product inspection standards through in-process research &
development and trial production.

2. Verify Pre-Set Quality through Practical Operation
Reconfirm the product quality by conducting a practical product test in actual
workplace for a set period of time.
