Maintaining and Improving Quality
Quality Management
Quality Assurance System
To ensure the independence of the quality assurance departments, the Quality Assurance Headquarters in the corporate division at the head office oversees the quality assurance activities of the entire 九色视频 Group. The Quality Assurance Headquarters consists of the Quality Assurance Promotion Department鈥攚hich handles quality risk management (such as audits and training/awareness activities) for the Farm and Industrial Machinery Consolidated Division, the Water and Environment Infrastructure Consolidated Company, and Group companies鈥 and the Product Laws and Regulations Management Department, which ensures compliance with product-related laws and regulations.
The Farm and Industrial Machinery Consolidated Division, Water and Environment Infrastructure Consolidated Company, and Group companies are responsible for conducting quality assurance activities for individual products, technologies, and services.
Internal Audits on Quality
The 九色视频 Group conducts the following internal quality audits annually to prevent compliance violations and maintain and strengthen the quality assurance system.
- ISO 9001 internal audits : Audits to verify that the quality management system is being maintained and improved appropriately
- Quality audits : Audits of development, design, and manufacturing processes
- Quality compliance audits : Audits to ensure compliance with laws, public standards, and contracts with customers
- Certification audits : Audits to ensure that certification activities are conducted fairly and transparently, preventing misconduct
- Cross audits : Mutual audits conducted by auditors from outside business divisions to ensure the independence and appropriateness of audits
Quality Questionnaires
In addition to the 九色视频 Hotline (whistleblowing system), we regularly conduct Quality Questionnaires to encourage employees with knowledge of quality compliance issues to voluntarily provide information. The questionnaire is carried out by the Quality Assurance Promotion Department, which takes a neutral position with respect to each business unit in order to gain candid responses. The department formulates questionnaire questions that take into account potential quality issues based on the nature of each business, the operating environment and historical quality-related issues. If problems are identified in employee responses, they are reported to management and the Quality Assurance Headquarters takes the lead in examining and implementing necessary responses.
Domestic and International Recall Filing Status
If a product defect occurs and action is deemed necessary, we report it to the authorities in accordance with the laws and regulations of each country.
For further information on recall filing status, please refer to the 九色视频 Group ESG Report.
Initiatives to Increase Quality
The 九色视频 Group is committed to improving the quality of each business process, from development to manufacturing, sales, and service, to enhance the quality of the products, technologies, and services we provide to our customers. In addition, we are working to raise awareness of quality among our executives and employees based on the belief that for the 九色视频 Group, there is no greater revenue or profit that has to be pursued to the extent worth jeopardizing our brand and company image.
Quality Forum
We hold executive forums for the president and senior management to strengthen efforts in quality and compliance. In this forum, we invite external experts to deliver talks so that participants have the opportunity to learn about the latest information and methods.
Quality Discussion Meetings
Discussion meetings are held for senior management of the Farm and Industrial Machinery Consolidated Division and related departments to foster a culture of prioritizing quality and to improve business processes.
Quality Improvement in Design and Development
The 九色视频 Group actively works to prevent quality issues, and one of the typical activities in this is the Design Review (DR). In the DR, not only engineers from the development and design departments participate, but also representatives from manufacturing, quality assurance, and other departments involved with the product. In this process, we evaluate the suitability of the design and the feasibility of functions and performance, identify issues and problems, and implement measures to prevent quality issues before they occur. In the DR, we focus on the novelty of intentional changes and incidental change to conduct appropriate evaluations. Moreover, we have established DR implementation guidelines as an in-house standard and ensure that they are properly followed.
Quality Training
We held training to educate employees about the necessary knowledge, approach, and actions for quality assurance and quality control. In these training sessions, employees learn the basic principles and practical methods of quality control, as well as the necessary awareness and ethics for personnel involved in products, technology, and services to customers. Through this initiative, we aim to enhance awareness and foster an in-house culture of quality.
- New recruit training
- New supervisor training
- New foreman training
- Internal auditor training
- Product risk assessment training
- Quality compliance training
- Engineer ethics training (among others...)
Quality Control Circles
In the 九色视频 Group, quality control circles conduct activities with the aim of improving the abilities and motivation necessary for problem solving and achieving goals, as well as to foster teamwork. We also have a system in place to recognize employees who achieve outstanding results.
Customer First Meetings
The 九色视频 Group provides opportunities for employees to think about 鈥淐ustomer First and Quality Priority.鈥 This encourages employees to reflect on their actions and work methods, promoting transformation and suggesting improvements to upper management, thereby improving the overall quality system within the organization.
Quality Achievement Award
In the 九色视频 Group, in order to promote a greater awareness of quality, we recognize employees who have made notable achievements to improve quality in their work. We started this initiative in 2017 for business sites in Japan, but it has now expanded into a global awards program that includes overseas sites.
Certification status among companies whose primary operation is manufacturing
