Implementation of Six Sigma in the DMAIC Approach for Quality Improvement in the Knitting Socks Industry
Öz
This study aimed to determine the level of sigma defects of socks and provide suggestions for quality improvements in reducing the percentage of socks defects. The scope of this research is in one of the garment industries with socks produced on the Lonati Single brand Knitting machine, which has decreased production due to production defects that do not meet the target. The methodology used in this study is the Define Measure Analyze Improve Control (DMAIC) approach and implementation of Six Sigma. The results of this study that the level of Sigma before a repair is 3.7017 and after the repair is 3.9614 and proposes that all improvement efforts be included in the Standard Operational Procedure (SOP) to be documented and applied because the percentage of socks defects decreased from 11.08% to 5.54%.

Bu çalışma, çorapların sigma kusurlarının seviyesini belirlemeyi ve çorap kusur yüzdesinin azaltılmasında kalite iyileştirmeleri için önerilerde bulunmayı amaçlamıştır. Bu araştırmanın kapsamı, üretim hatalarının üretim hedeflerinin karşılanamaması problemine neden olduğu, bu sebeple üretimi azalmış olan ve Lonati Single marka örme makinesinde üretilen çorapların yer aldığı hazır giyim sektörlerinden biri üzerinedir. Bu çalışmada kullanılan metodoloji, Define Measure Analyze Improve Control (DMAIC) yaklaşımı ve Altı Sigma'nın uygulanmasıdır. Onarım öncesi Sigma seviyesinin 3.7017 ve onarım sonrasının 3.9614 olduğu bu çalışmanın sonuçları; tüm iyileştirme çabalarının dokümantasyonunun sağlanması ve uygulanabilmesi için Standart Operasyonel Prosedüre (SOP) dahil edilmesini önermektedir çünkü çorap hataları çalışma ile 11.08%’ den 5.54%’ e düşürülebilmiştir.
