Quality Assurance Committee

In 2006 the Daido Group established the Daido Group Quality Assurance Committee in what was a rapidly changing social environment. The Committee is chaired by a managing director, and Committee members consist of the eight plant managers of Daido Steel and division heads of 13 manufacturing-related companies.

The Committee for the Daido Steel Group is conducting activities to solidify customer trust by sharing information to achieve early solutions of critical issues, improving common issues to pre-empt quality complaints, and by using basic activities to reinforce the quality assurance infrastructure.

The Committee also concentrates on training programs such as quality education for certification, and the up skilling of front-line workers through competitions.

Quality Education

Daido Steel places great importance on quality education for front-line workers based on the Company’s fundamental idea that quality is created at the job site.

Specifically, education by job grade is given to all employees on Q7 techniques (such as Pareto charts, scatter plots, and characteristic diagrams), N7 techniques (such as relational diagrams, system diagrams and matrix diagrams), and IE techniques (such as process analysis, work process analysis, and utilization analysis/ratio-delay studies). These techniques are utilized in the execution of the field improvement activities including self-management activity (JK (jishu kanri: self-management), which is small-group activities). Groups that implement excellent self-management activities are given an award.
