Yamaha Quality Control: Quality Management
Yamaha's Quality & Engineering Planning Division handles testing requested by the various product development divisions in accordance with the Yamaha Quality Management System. The Yamaha Quality Management System for professional audio products conforms to ISO9001:2015 standards and is certified by BV (Bureau Veritas — an internationally recognized certification company based in France). Its standards are applied and maintained from product planning through development and production to sales. The Yamaha system, however, has been customized to even more stringent criteria that reflect some very ambitious internal quality goals. The Quality Management System applies not only to operations in Hamamatsu, Japan, but to all other Yamaha pro audio factories in Japan and Indonesia as well. The all-inclusive scope of the system ensures that the same policies, objectives and standards are shared by all Yamaha pro audio staff and facilities, no matter where they may be, so that the required level of product and service quality can be maintained on a worldwide scale.
