Syarikat mesti berusaha untuk meningkatkan kualiti dan produktiviti produk atau proses untuk maju bersaing. Sebahagian daripada tujuh alatan asas kawalan kualiti merupakan suatu teknik yang sangat berkesan untuk mencapai objektif tersebut. Kajian kes yang telah dijalankan di syarikat "plastic injection moulding" tempatan telah mengaplikasikan sebahagian daripada tujuh alatan kawalan kualiti dan keputusan menunjukkan purata bulanan kualiti kecacatan produk menurun dari 13.49% ke 7.4%. Untuk mencapai kejayaan seterusnya dalam mempertingkatkan kualiti produk, sokongan daripada pihak atasan syarikat amatlah diperlukan. Kata kekunci: Kawalan Kualiti Berstatistik; "Plastic Injection Moulding"; carta kawalan 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.
