Without his invaluable help and dedicated involvement at every step of the process, this thesis would not have been possible.
Secondly, I would like to extend my heartfelt thanks to all the teachers in the Department of Industrial Engineering who have enthusiastically imparted a wealth of knowledge to me during these two years. Lastly, and most importantly, I would like to express my deepest appreciation to my husband and my two children for their unwavering support and assistance throughout my journey of studying and writing this thesis. I take full responsibility for any errors or inadequacies that may be present in this work. ii ABSTRACT ISO 9001:2015 and Lean Six Sigma methodologies are widely adopted by companies worldwide nowadays.
While there have been studies integrating these approaches into a single framework, they have generally remained at a generic level without delving into specific sectors. In Vietnam, there is a growing need to implement ISO 9001:2015 and Lean Six Sigma as a means to assess a company's readiness to join the global supply chain. However, many small and medium Vietnamese companies are facing difficulties in applying the above systems due to the lack of available guidance to facilitate the integration of these practices. This research focuses on developing an integrated system of ISO 9001:2015 and Lean Six Sigma tailored specifically for the furniture manufacturing industry.
The aim is to enhance the industry's capabilities and improve its competitiveness in the market. Building upon previous integration frameworks, this research provides a detailed examination of each ISO 9001 requirement and identifies the appropriate processes and Lean Six Sigma tools to complement them. The proposed integrated system has undergone review and been accepted for implementation at a furniture manufacturing company. It is specifically designed for the furniture manufacturing industry, enabling the application of ISO 9001:2015 and Lean Six Sigma with greater ease and efficiency.
It also reduces the risk of misapplying ISO standards and Lean Six Sigma tools. This tailored integrated concept map can be further developed and extended to other leading industries in Vietnam, such as textiles, footwear, and food processing. By doing so, it will contribute to improving the competitiveness of Vietnamese companies in the market. iii TÓM TẮT LUẬN VĂN THẠC SĨ Hiện nay, hệ thống quản lý chất lượng theo tiêu chuẩn ISO 9001:2015 và phương pháp Lean Six Sigma được các công ty trên toàn thế giới áp dụng rộng rãi.
Mặc dù đã có những nghiên cứu để tích hợp các cách tiếp cận này thành một hệ thống duy nhất, nhưng chúng vẫn dừng ở các mô hình chung chung mà không đi sâu vào bất cứ lĩnh vực cụ thể nào. Tại Việt Nam, nhu cầu triển khai ISO 9001:2015 và Lean Six Sigma như một cách thức để đánh giá mức độ sẵn sàng tham gia chuỗi cung ứng toàn cầu của một công ty ngày càng tăng. Tuy nhiên, nhiều công ty vừa và nhỏ của Việt Nam đang gặp khó khăn trong việc áp dụng các hệ thống trên do thiếu các tài liệu hướng dẫn thực hiện tích cả tiêu chuẩn ISO 9001:2015 và các công cụ Lean Six Sigma vào hệ thống quản lý hiện có của công ty. Nghiên cứu này tập trung vào việc phát triển một hệ thống tích hợp ISO 9001:2015 và Lean Six Sigma được thiết kế riêng cho ngành sản xuất đồ nội thất.
Mục đích là để tăng cường khả năng và nâng cao khả năng cạnh tranh của nó trên thị trường. Dựa trên các mô hình tích hợp đã đề xuất trước đó, nghiên cứu này thực hiện xem xét chi tiết về từng yêu cầu của ISO 9001 và xác định các quy trình và công cụ Lean Six Sigma thích hợp đáp ứng các yêu cầu của tiêu chuẩn, qua đó từng bước hình thành hệ thống quản lý tích hợp. Hệ thống tích hợp đề xuất đã được xem xét và được chấp nhận để triển khai tại một công ty sản xuất đồ nội thất. Hệ thống được thiết kế đặc biệt cho ngành sản xuất đồ nội thất, cho phép áp dụng ISO 9001:2015 và Lean Six Sigma một cách dễ dàng và hiệu quả hơn, giúp làm giảm nguy cơ áp dụng sai các tiêu chuẩn ISO và các công cụ Lean Six Sigma.
Mô hình khái niệm tích hợp phù hợp được hình thành trong nghiên cứu có thể được tiếp tục phát triển và mở rộng sang các ngành công nghiệp hàng đầu khác ở Việt Nam, chẳng hạn như dệt may, da giày và chế biến thực phẩm. Qua đó sẽ góp phần nâng cao năng lực cạnh tranh của các doanh nghiệp Việt Nam trên thị trường. iv THE COMMITMENT OF THE THESIS’ AUTHOR I hereby declare that the master’s thesis titled ―Integrating ISO 9001:2015 Standard and Lean Six Sigma Tools into a Quality Management System.
