Murata has established a Quality Policy to provide high-quality products that gain the trust and satisfaction of its customers.

We display posters bearing this policy in our workplaces to cultivate the awareness of employees. The policy is also distributed on a card for employees to carry with them to ensure they are thoroughly cognizant of the policy's content.

We remain committed to the continuous development of unique products and the cultivation of new areas of expertise. Our underlying approach is our belief that “better equipment is made from better parts and better design, and better parts are made from better materials and better processes.” With this belief, we consistently manage every stage, including design, material selection, procurement, production, sales, and servicing in cooperation with all members who comprise the Murata Group—top management to individual employees—by employing the Deming circle. In this way, we can economically produce quality products that meet market needs with full consideration for the natural environment.

Murata employs the Deming circle approach to ensure thorough quality management.

The Deming circle focuses on the sequence of processes in supplying products to customers by investigating and analyzing customers' needs and reflecting these results in product manufacture. Through this approach, we continuously augment the quality of our products by repeating a cycle of planning and design, manufacture, sales, and surveys and services.

In the design of products and manufacturing process and in the extending applications, Murata implements design reviews (DRs) to ensure high-quality products. Newly designed products, processes and applications pass through three phases: concept design (development phase), detailed design (practical design phase) and industrial design (industrialization phase). In each of these, Design Departments, design review functions and Quality Assurance Departments participate in carrying out DRs. The general manager of the Quality Assurance Department holds ultimate decision-making authority on acceptance and rejection, and any products and processes not achieving the requisite criteria are prevented from progressing to future stages.

All Murata Group plants inside and outside Japan have received quality management system ISO 9001 certification. Our quality management systems have also acquired ISO/TS16949 certification, a stricter international standard specific to the automotive industry.

Furthermore, the Quality Assurance Department at our Yasu Plant has been awarded ISO/IEC17025 certification for testing and calibration (inspecting the accuracy of measuring instruments) and gained Japan Calibration Service System (JCSS) accreditation. The department is also bolstering the level of its quality evaluation technologies.

As a globally developing corporation, the Murata Group is improving its quality systems on an ongoing basis to ensure uniform quality standards worldwide.
