Improving the Quality of Products
Sony pursues design-, manufacturing- and parts-related initiatives aimed at improving product quality.
Design-related quality initiatives
In the initial stages of the design process, the individual in charge of a particular business group verifies new technologies and new parts and, from a user's perspective, determines how a product is to be used. At the conclusion of the design process, the individual in charge confirms the degree to which the intended level of product quality, reliability and usability has been realized.
In addition, to ensure our ability to provide customers with products of a quality worthy of the Sony brand, we required OEM/ODM companies and parts suppliers to comply with Group-wide quality standards. Compliance with these standards is also tested at the end of the design process.
Such approaches prevent the occurrence of problems pertaining to new technologies and new product parts, as well as ensure product designs that incorporate consideration for user convenience.
Manufacturing-related quality initiatives
In its effort not to receive, manufacture or ship anything with quality-related problems, Sony adheres to a policy of workmanship at all of its manufacturing sites that ensures customers can use Sony products with confidence. Initiatives include setting important targets at each site and implementing Plan-Do-Check-Act (PDCA) processes, thereby facilitating the achievement of such targets and the continuous improvement of product quality. Sony has also established standard product quality rules to ensure Sony products manufactured by OEM/ODM companies are of the same high quality as those manufactured at Sony production sites.
Parts-related quality initiatives
Recognizing the importance of parts and determined to manufacture products built for long-term use, Sony carefully selects key parts independently for each of its major product categories and is pursuing focused efforts aimed at increasing the reliability of the parts it uses through cooperation with relevant departments and Sony's headquarters.
Improving Product Safety
Ensuring the safety of the customers who use Sony products is one of the highest priorities for the Sony Group. Accordingly, at every stage of its business activities, including product development, planning, design, production, marketing, and after-sales service, Sony takes steps to comply with safety standards based on laws and regulations while constantly striving to surpass those standards in order to maintain the safety of its products. As part of these efforts, Sony appoints managers in charge of product safety assessment from a medical perspective. When developing products employing new technologies, Sony also seeks advice on product safety from a medical perspective from outside experts, which it then incorporates into product development, design and engineering. When deemed necessary, Sony also conducts evaluation tests to assess safety with the assistance of a specialized organization.
In addition, Sony strives to ensure that the safety-related explanations and information it provides to customers are accurate, easy to understand, and clearly presented. If a safety-related problem involving a Sony product is reported, the Sony Group immediately collects information and examines the facts, and then takes the steps necessary to rectify the problem.
Improving the Long-Term Reliability of Products
The Quality Reliability Lab continues to enhance Sony's product reliability, thereby ensuring Sony's ability to deliver safe, durable and reliable products to customers.
Sony has assigned specialists to work full time on improving technologies essential to product reliability and continues working to ensure the long-term reliability of its products by developing elemental technologies for preventing the deterioration, wear and corrosion of materials and parts, as well as technologies necessary to ensure the reliability of new technologies and products and to evaluate such technologies and products.
The reliability and evaluation techniques, and the information obtained through these activities, are openly accessible and available to all Sony employees via training sessions, seminars, and websites, and are utilized to improve design and parts selection processes. Sony also presents some of its own knowledge on evaluation techniques at academic meetings and industry conferences and gatherings, in its efforts to contribute to the industry.
