Structure Promoting Quality Control

KIOXIA Group has implemented a structure aimed at strengthening our quality-control activities. Led by our CEO, a quality control meeting is held twice a year in which our Quality Officers, Vice Presidents, Technology Executives, General Managers, and Senior Managers participate and where they discuss and decide on key issues of quality policy. The participants also evaluate the appropriateness and validity of quality management and risk measures. We communicate decisions made during these meetings to business divisions and ensure that they are actioned.

Improving the Quality Management System (QMS)

KIOXIA Group has obtained ISO9001 certifications, the basis of all quality management systems, and ISO/TS16949, a more advanced certification. Rather than merely assessing whether our products meet the requirements of these standards, we also endeavor to improve their overall effectiveness. We evaluate our products’ annually based on the eight QMS principles and other guidelines.

Improving Design Quality

In order to enhance our ability to ensure product quality at the design stage, KIOXIA Group conducts Failure Mode and Effects Analysis (FMEA) in order to prevent defects from reaching upstream. The aim of this activity is to enhance quality by anticipating failures or defects, called failure modes, targeting product design and processes in the later stages of development. We are implementing practical education to broaden the base of FMEA activities which is  leading to better FMEA processes.
