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 Executive, 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.

Structure of Response to Product Issues

Information on issues involving KIOXIA products in the market is collated by the KIOXIA CEO, who is also the Chief Quality Executive Officer, or Quality Executive, through what we call CPL1 Incident Response Liaison. We then take necessary action after consultation with our QS2 Risk Committee.
No serious quality incidents occurred in FY2020.

  1. CPL is an abbreviation combining CL (contractual liability) and PL (product liability).

Improving the Quality Management System (QMS)

KIOXIA Group has obtained ISO9001 certification, 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 implement practical education to broaden the base of FMEA activities which is leading to better FMEA processes.
