Abstract.

In order to survive in a competitive market, improving quality and productivity of product or process is a must for any company.

Some simple techniques like the “seven basic quality control(QC) tools” provide a very valuable and cost effective way to meet these objectives.

This paper presents a case study in which a local plastic injection moulding company deployed some part of the “seven basic quality control(QC) tools” to significantly improved the monthly defect quality from 13.49% to 7.4%.

However, to make them successful as cost effective and problem solving tools,  strong commitment from top management is required.
