Abstract
It is evident that the quality of parts obtained from suppliers affects the quality of the products. The improvement of supplier quality can be obtained by longterm collaboration of the company and the supplier. This collaboration not only improves the quality of the supplier and the company but also improves delivery time, cycle time, productivity and profitability. As the companies grow and the products get complex, interaction between products increase and then the lack of quality becomes more complicated problem. Therefore, statistical and non-statistical tools and methods are used for the improvement practices of supplier quality. Recently, six sigma method is mostly preferred for quality improvement practices because this method is required to use too many quality tools and allows measurement of improvement by sigma and financial value.In this study, it is shown that six sigma method can be applied to supplied component in car manufacturing.. The method is used for improvement of the dyeing failure on FRP back wall of the cars. Sigma level increased from -1.97 to 1.48 and it was saved 9.14 € per car after corrective actions are applied both to the manufacturer and the supplier

Abstract
İşletmelerin tedarik ettikleri parçaların kalitesinin ürünlerinin kalitesini etkileyeceği açıktır. İşletme ve tedarikçisi arasında uzun dönemli işbirliği ile tedarikçi kalitesinin iyileştirilmesi sağlanabilecektir. Bu durum hem tedarikçi hem de işletmenin kalitesi ile birlikte, teslim süreleri, çevrim süresi, verimlilik ve karlılıklarında da iyileşmeler sağlayacaktır. Ancak işletmeler büyüdükçe ve ürünler karmaşıklaştıkça girdilerin birbiri ile olan etkileşimi artmakta ve kalitesizlik çok daha karmaşık sorun haline gelmektedir. Dolayısı ile tedarikçi kalite problemlerinin iyileştirme çalışmalarında pek çok istatistiksel ve istatistiksel olmayan araç ve yöntemden yararlanılması söz konusu olmaktadır. Altı sigma yöntemi son yıllarda kalite iyileştirme çalışmalarında en çok tercih edilen yöntem olma özelliğindedir. Çünkü yöntem pek çok kalite aracından yararlanmayı istemekte ve iyileşmenin sigma gibi bir ölçekle ve finansal değerle ölçülmesini sağlamaktadır.Bu çalışmada çok sayıda tedarikçiye sahip bir otomobil üreticisinin tedarik edilen bir üründe Altı Sigma yöntemi uygulanabilirliği gösterilmektedir. Çalışma araç FRP arka duvarı üzerindeki boya hatalarının iyileştirilmesi ile ilgili yapılmıştır. İyileşme önerileri hem işletme hem tedarikçi işletme için uygulanarak sigma düzeyinde -1.97 den 1.48’e artış ve araç başına 9.14 € luk kazanç elde edilmiştir
