薄膜液晶顯示器（Thin film transistor liquid crystal display，TFT-LCD）是一關鍵之產業，它可應用之領域非常廣泛。在現今競爭之市場上，一個有效的新產品開發系統是提高企業競爭力之主要做法。有多數的TFT-LCD企業已開始增加注意力在新產品之開發，以確保提升公司銷售量及利潤。當各企業開始在加速新產品之開發時，供應商也開始被要求遵循並縮短它們的新產品開發時程，而這也已成為多數供應商所關注之焦點。然而在如此高度競爭性之環境底下，供應商往往會不正確的刪除或省略一些新產品開發步驟以符合客戶之需求。也因如此，供應商常常會遺漏一些基本要求之規格標準而導致新產品開發之失敗。
在TFT-LCD之供應鏈裡，只有產品設計工程師會參與協助供應商之材料品質問題之改善。然而，多數的設計工程師不懂得如何有效的管理供應商。另一方面，供應商品質管理部門（Supplier quality management，SQM）只有在量產階段會參與供應商品質管理活動，並未參與到新產品階段之管理。為了提升產品之品質及客戶滿意度，供應商品質管理部門必須發展一個快速且有效的新產品開發管理模式來確保供應商之新產品開發品質。本研究提出一個供應商新產品品質管理模式以及推行程序，以協助企業可以在新產品開發及驗證初期提早偵測供應商相關之品質問題。本研究以一個TFT-LCD製造商之真實案例來驗證所提出之模型和程序的有效性。

Thin film transistor liquid crystal display (TFT-LCD) is a key industry whose technology has many applications. An effective new product development (NPD) system is the key to the competitiveness of new products in the market. Thus, numerous TFT-LCD enterprises have increasingly focused on and invested in NPD to ensure increased sales and profitability. When enterprises accelerate NPD, suppliers are also forced to follow and shorten their development schedule. This conformity has become the focus of most suppliers. However, under a highly competitive environment, vendors often inappropriately delete or omit several processes in NPD to meet business needs. Suppliers also frequently lack a clear standard, which leads to the failure of NPD.
In a TFT-LCD supplier chain, only product designers are involved in NPD to identify problems in supplier material quality. However, these designers do not understand how to manage suppliers effectively. Moreover, the supplier quality management (SQM) division is only involved in the management activities during mass production, not during the NPD process. To enhance product quality and ensure customer satisfaction, the SQM division must have a fast and effective NPD management model to confirm supplier development quality. Therefore, this study proposes a supplier new product quality management model and its implementation procedure to aid enterprises in the early detection of quality issues in the initial development and verification process. A real case study from a TFT-LCD manufacturer is used to demonstrate the effectiveness of the proposed model and procedure.
