The Quality Assurance Department, which had been working to improve service quality and planning and support activities related to the service department, transferred its planning and support activities related to the service department to the Service Planning Department in April 2014. In October of the same year, the ISO Promotion Center, which had been established in October 2008, was integrated and ISO operations began.
In April 2019, the Quality Assurance Division was newly established to strengthen the organizational structure under the division, and the job system was revised to a two-departments system. We have the Quality Assurance Department, which is responsible for improving the quality of the services (services, parts, products) provided to customers, and the Quality Planning Department, which is responsible for promoting technical and environmental compliance and ISO and environmental activities, and clarified the missions of both departments and strengthened their practicality.
Since then, the Quality Assurance Department has been renamed the Service Quality Department in April 2021 and the Service Quality Promotion Dept. in April 2024, and it continues to the present day.
In addition, the Hitachi High-Tech Science BT (Beam Technology) Service Business was transferred to our company in April 2021, and the Healthcare Business Service Division of Hitachi, Ltd. was transferred to our company in April 2024. With this transfer, our service quality is required to have even higher service technology and quality to respond to product diversification, and we are Service Quality Promotion dept. and improvement activities in collaboration with the people in charge of quality promotion in each service department.
The mission of the department for fiscal 2024 is to promote activities to maintain and improve service quality as the " Service Quality Promotion Dept.," which connects customers and engineers with safety and service quality, based on the concept of "the base is the starting point."

In April 2015, we introduced a technical certification system and revised the method for determining the technical level of devices and operating the similarity evaluation table. In March 2017, the technical certification system was revised with the aim of maintaining and improving service quality, including the addition of certification test items for each product group by department, and the implementation of maintenance confirmation tests every five years to confirm that the technical level is being maintained.

In recent years, when there is a need for further strengthening of risk management and fraud prevention measures related to social trust, it is essential to continue maintaining and improving service quality in order to eliminate service accidents and ensure social trust. In collaboration with the Hitachi High-Tech Quality Assurance Division and Product QA, we will work to ensure that all basic tasks are carried out in unison with each service division, and that safety and health are prioritized above all else, by repeating education and other measures to ensure that "Safety > Quality > Delivery > Cost" is put into practice.
In addition, in fiscal 2024, we will formulate service indicators to standardize the operational status of field products worldwide, and from fiscal 2025, we will work with the Hitachi High-Tech Customer Success Division and other relevant departments to standardize the technical certification system in the same way.
Service parts are also essential for ensuring the stable operation of customer equipment, and in April 2014 we launched a Parts QA Group to strengthen our response to defects at the manufacturer, including the inspection of purchased parts and the management of non-conforming products, and we will continue to work to improve the quality of service parts.
