摘要

6 sigma曾為許多世界級企業帶來傲人的績效，尤其帶領奇異(GE)公司邁向顛峰，成為該公司採行之最重要的管理措施。6 sigma使企業在改善問題的能力、管理體系的效能、管理思維與邏輯，以及內部溝通、知識分享等各方面有卓越的貢獻，使得6 sigma將成為追求高競爭力企業的最佳管理工具。本研究希望藉由我國已導入6 sigma之企業，透過問卷調查與專家訪談方式，了解我國企業導入6 sigma之作法與其對績效之影響。
本研究以國內已導入6 sigma之製造業為主要研究對象，研究方法以奇異推動6 sigma內涵特徵的九個構面，經由文獻與專家修正，對應九個構面整理出36項措施，作為國內企業導入6 sigma之作法之衡量變數，並以企業導入6 sigma產生的「六項績效指標」為應變數；經由迴歸分析與專家訪談，得到下列研究結果︰

1.企業導入6 sigma之做法與「成本與品質不良率降低」的績效呈現正相關。
2.企業導入6 sigma之做法與「業績成長、獲利增加、縮短交貨週期」等績效無顯著關係。
3.企業導入6 sigma之做法與「顧客滿意提升」的績效呈現正相關。
本實證研究之結果，可供國內急欲導入6 sigma之企業的參考依據，使其導入6 sigma更為順利，有效達到提升競爭優勢的目標。
