隨著科技的發展與3C產品的普及化，筆記型電腦幾乎已經成為開發或已開發國家中人人必備的消費型電子產品，其市場發展已經相當成熟。近年來，伴隨著智慧型手機﹅平板電腦等產品的不斷疊代，筆記型電腦中也出現了二合一便攜本或稱為可拆卸式筆記型電腦這類的新鮮產品。這類產品開始吸引消費者的目光與增強其購買意願，因此越來越多的品牌業者紛紛加入與推出二合一的筆記型電腦，也為本來趨於飽和的筆記型電腦市場的未來發展留下了懸念。
本研究針對個案公司銷售的可拆卸式筆記型電腦在市場上所遭遇高客退率的問題，運用精實六準差DMAIC手法進行改善。在本研究中，專案小組藉由界定﹅量測﹅分析﹅改善與控制有系統性的方法找出影響產品品質的真正因素，透過有效的監控主要零組件組裝治具的磨損程度，將製程不良率由原20.9%降低至3.5%，並導入自動化測試設備，消除人員的誤判與將作業時間由原24分鐘縮減至17.5分鐘。最後利用統計製程管制圖與定期的品質會議等方式管理與監控生產製程，避免再發。在實施改善方案後，客退率從3.09%降低至2.01%，每年預估可節約成本達77萬美
金，其中包含44萬美金的外部失敗成本。

Laptop computers are readily becoming a necessity in people’s life regardless whether you are residing in developing or developed countries due to consumer technology evolving at an unprecedented pace.
With the constant roll out of smart phones and tablets, a new form factor Hybrid emerged within traditional notebooks lineup. With customers around the world quickly embracing Hybrid products named detachable notebooks, this led to many more manufacturers joining the Hybrid race. Hybrid’s emergence has created market growth opportunities for the laptop market that was thought to be converging on the point of saturation.
In this thesis, we focus on the problem that company is dealing with. Base on the DMAIC steps of Six Sigma and Lean tools, the project team found out the main factors affecting the product quality. By controlling the degree of wear, the production defective rate was decreased from 20.9% to 3.5% and the field failure return rate was
decreased from 3.09% to 2.01%.
The project team also implemented the automatic testing equipment and let the operations time down to 17.5 minutes from 24 minutes. Finally, by using SPC tools and daily quality review meeting, the management and engineering teams can easily manage the quality performance and prevent it recurrent. The estimated annual cost
saving is up to $777,231 including $416,691 warranty cost.
