Quality Assurance

  Guided by a key component of its overarching philosophy, the Yamaha Group engages in Customer-Oriented and Quality-Conscious Management. In its efforts to fully satisfy its customers, the Group offers quality products and services that incorporate new and traditional technologies as well as refined creativity and artistry.

Quality Management System

  The Yamaha Group has put in place a Group-wide quality management system to ensure the production of high quality products and the provision of high quality services (see the Yamaha Group Quality Management System diagram).

  Under this system, quality policies and targets as well as important quality-related measures being implemented by the Yamaha Group are deliberated by the Quality Committee and then issued from the president to operating divisions. Each business division sets its own divisional targets in line with the quality policies and objectives set by the president. All production bases both inside and outside Japan follow ISO 9001 international standards for quality management systems or operate a management system in compliance with this and engage in activities designed to achieve quality targets.

  The Quality Assurance Division confirms the status of achievement based on monthly quality reports submitted by each business division, conducts monitoring based on the quality audits (see next item) and submits the results to the Quality Committee.

  The Quality Management Representative Conference, which comprises officers in charge of quality management from each business and sales division, reports on initiatives in each division, shares information and reflects this in examinations of policy aimed at resolving common challenges.

Quality Audit

  Yamaha Corporation’s Quality Assurance Division conducts audits to check whether the quality assurance systems of each business division as well as nd checks that the quality of products and services meets the standard to which the Yamaha Group aspires. While urging the necessary improvements, the results of these audits are taken into account in improving the Company-wide quality management system.

  Each business division instructs and audits the factories both inside and outside Japan over which they have control. Every effort is made to further enhance product quality.

Acquiring ISO 9001 Certification

  As of March 31, 2013, the Yamaha Group had acquired certification under the ISO 9001 international standard for quality management systems at 25 business divisions in Japan and overseas. These 25 divisions make up 71% of the entire Yamaha group on an employee numbers basis.

Quality Management Training

  In order to develop human resources capable of contributing to improvements in quality, the Yamaha Group's personnel training system is comprised of expert training related to “quality assurance,” as well as training tailored to individual job positions. The goals of this system are to raise awareness and enhance skills with respect to quality management. The Group has prepared offered courses covering a wide range of such topics in fiscal 2012 including as quality engineering, FMEA and FTA*1, with 149 people taking part in fiscal 2012.
