Background to Identification as Materiality

Significance for TDK

The improvement of product quality and delivery performance will raise the satisfaction of 2CX (customer experience and consumer experience) and lead to the further use of TDK products by customers for their existing products and new development projects. As a result, it will contribute to expanding usage and shares at customers and enhancing orders received, sales, and income.
At the same time, by reducing in-process defects (quality failure costs) at manufacturing sites, it will contribute to the raising of Commercial Value and Asset Value in “Value Creation 2023," the TDK Group’s Medium-Term Plan.

Significance for Society

TDK products are developed, produced, and supplied to the market with the aim of realizing our Corporate Motto of “Contribute to culture and industry through creativity” and our Sustainability Vision of “Technology for the well-being of all people.” However, the occurrence of quality defects not only makes it difficult to achieve our objectives but also could lower customer satisfaction and cause damage to society.
Quality initiatives are an important factor for the realization of our Corporate Motto and Sustainability Vision. Since this effort to realize our Corporate Motto and Sustainability Vision is also connected to the solution of issues raised in the United Nations Sustainable Development Goals (SDGs), such initiatives have an important significance in supporting TDK’s role in society.
We believe that stakeholders also expect TDK to lower risks relating to product quality and to continue the stable supply of high-quality products.

Responsible Themes

  • Pursue zero-defect product quality
  • Reduce quality costs
  • Maximize customer satisfaction with product and service quality

For TDK, a manufacturing company, the ultimate goal is to realize zero defects, but we have not reached that point yet. To achieve our objective, at the moment we are bolstering efforts in the four steps: identification of causes, outflow prevention activities, preventative and predictive activities, and upstream-management-type manufacturing that does not produce defects. In each step, we are improving ways and means to raise the quality awareness of employees and promoting activities to eliminate defects in design, material, process, and management through integration with digital transformation (DX). In addition, we are striving to predict and prevent the outbreak of in-process defects through DX technology, including the building of basic technologies for deep learning*1 and AOI.*2 For TDK, which designs, manufactures, and supplies products, product quality is a most important issue and a foundation of our corporate activities. The TDK Group will come together, eliminate product defects in the four areas of design, material, process, and management, and establish an organization and corporate culture of upstream-management-type manufacturing so that “Made by TDK” becomes a synonym of top quality.

  • *1 Deep learning is a type of machine learning that boosts learning ability by combining artificial neural networks imitating the neural circuits of the human brain, thereby enabling the learning of various things and response to complicated problems.
  • *2 AOI stands for automated optical inspection, which refers to the quality inspection of products by means of continuous photography using a high-resolution camera system with different light sources, such as fluorescence, ultraviolet rays, LED (light-emitting diode), and infrared rays.

  • Maximize customer satisfaction with product and service quality

As a supplier, we make efforts to provide value in the form of deliveries that do not dent the customer’s business and also to enhance asset efficiency. As a result, we can maximize the satisfaction of customers and gain their trust. Furthermore, we believe that TDK’s tackling, as a supplier, of the twelfth Sustainable Development Goal of “Responsible consumption and production” will lead to the strengthening of our response to geopolitical risks, our consideration for society and the environment, and the governance needed to put related measures into practice.
To realize our goals in three years, we are currently promoting the “establishment of factory foundations based on plan-based production and on-time delivery,” and “standardization and refining of operation processes between sales companies and factories.” In addition, we will shift from the existing specific-optimal-type management of supply and demand to seamless supply chain management with a consolidated and overall-optimal perspective and realize quick decision making in a VUCA* world.
The improvement of delivery has been an important issue for many years. The TDK Group will maximize customer satisfaction by working together to transform into new operation processes and overcome this challenge.

  • * VUCA is an acronym standing for volatility, uncertainty, complexity, and ambiguity. It refers to conditions that are highly unpredictable for society and business.
