摘要

精實製造與六標準差為目前最被廣泛討論與應用的兩種品質改善手法，兩者同時運用則稱為精實六標準差，可兼具精實方法縮短流程時間與六標準差減少變異的優點，目前以六標準差為主要架構之改善手法已普遍應用於製造及服務等產業。台灣在歷經921大地震等天災後也喚醒大眾對於施工品質的重視，因此目前國內各大知名營建企業皆強調以品質作為其公司特色；而六標準差正是一套重視顧客所關注的品質並同時達成效率提升的管理手法，可協助企業追求品質與降低成本，因此六標準差手法的思維應當也可運用營建產業。
預鑄工法目前在各種類型的營建工程的應用已相當常見，舉凡橋梁工程、隧道環片及建築結構等。因此，本文將以預鑄構件生產為例，運用精實六標準差手法進行營建生產力的改善，探討本項手法應用於營建工程的可行性，並比較改善前後不同的管理模式所造成的差異。最後提出應用於營建相關應用的建議，期能提供持續改善營建品質與提昇企業競爭力之參考。

Lean Production and Six Sigma are two quality improvement initiatives which have been widely discussed and applied in practice. The integration of these two initiatives is called Lean Six Sigma, and could take the advantage of both, that is, Six Sigma helps to eliminate defects, and Lean Production could shorten the flow period. Nowadays, using Six Sigma as the basic methodology for improvement has been generally applied in the manufacturing and service industries. In Taiwan, after the 921 earthquake and other huge disasters, the attention of the quality of construction had been awakened; therefore, all the well-known construction enterprises have emphasized the company characteristics with quality. Six Sigma takes attention to the quality that customers concerned and also contribute to the growth of profitability and efficiency. By the way, the thinking of Six Sigma approach should also be applied in construction industry.
The precast concrete is one of the construction methods currently applied in various types of construction projects. Therefore, this study will use the Lean Six Sigma as research method to improve the productivity of precast production, attempt to explore the feasibility for construction management, and compare the affection before and after different management models. The results of the study may provide recommendations for the construction-related application, and expect to enhance quality and competitiveness of construction enterprises.
