Quality Management System

Our mission is to provide customers with quality products and services that meet or exceed their expectations.
Quality Management (QM) is the management of all activities required to maintain and continuously improve this level of excellence and includes quality planning, assurance and control. The continuous improvement of quality is based on a Quality Management System (QMS) that aims for total customer satisfaction where emphasis is given to all aspects of quality to handover a product to the customer that satisfies all requirements.

QM for Customer Satisfaction by the Plan-Do-Check-Act (PDCA) Cycle

The first stage of customer satisfaction begins with our daily works. Normal business routine provides the most suitable platform for employees and organizations within Chiyoda (customers in the Company) to accomplish their duties and this practice will lead to customer satisfaction.
Continuous improvement stems from understanding a process that requires improvement and includes collecting and analyzing information such as customer satisfaction reports and complaints (feedback).

Concept of QM / QC / QA

The conceptual diagram for optimization of roles to deliver a product or service which focuses on meeting or exceeding customer expectations is shown below. QM commences with “customer focus”, provides confidence of meeting or exceeding customer expectations (Quality Assurance) and includes procedures to ensure established quality criteria are met (Quality Control).
