摘要

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 increasing the competitiveness of new products in the market. Thus, numerous TFTLCD enterprises have increasingly focused on and invested in NPD to ensure increased sales and profitability. When enterprises accelerate NPD, suppliers are forced to follow and shorten their development schedule. This conformity has become the focus of most suppliers. However, under a highly competitive environment, vendors frequently delete or omit several processes inappropriately in NPD to meet business needs. Suppliers also frequently lack a clear standard, which leads to NPD failure. To enhance product quality and ensure customer satisfaction, the supplier quality management (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 detecting quality issues during the initial development and verification process. An actual case study of a TFT-LCD manufacturer is used to demonstrate the effectiveness of the proposed model and procedure.

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他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。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。
