A Company is mainly engaged in production of notebook casings, and the outer casing is made of aluminum, such as stamping parts, CNC and a series of mechanical processing and anodizing parts. Many abnormalities are found in the production process, especially after the anodizing treatment, a black line defect appears on the product surface which makes the white background sharply contrasted, causing a large number of scrapped products. The Company decides to hire LeanChina Management Consulting Co., Ltd. to fully promote Six Sigma management. What is the purpose for the company to apply the Six Sigma DMAIC?
A. To improve existing process to solve the design problem of aluminum alloy parameters
B. To use a structured process to solve the design problem of aluminum alloy parameters
C. To convert qualitative needs to quantitative parameters
D. To forecast future sales that take into account inflation factors

某公司主要生产笔记本外壳,外壳为铝材需经过冲压、CNC等一系列机械加工以及阳极氧化处理。在生产过程中异常较多,尤其是阳极处理后产品表面出现一种黑线残缺,在白色底色上反差特别大,造成了大量产品报废。该公司决定聘请天行健康管理顾问公司全面推动六西格玛管理,公司应用六西格玛DMAIC的目的是什么?

A. 改进现有流程进而解决铝合金参数的设计问题

B. 使用结构化的流程解决铝合金参数的设计问题

C. 把定性需要转化为定量参数

D. 预测考虑了通胀因素的未来销售

参考答案: A

详细解析:

该题考察的核心是六西格玛法中DMAIC方法的目的。 (第四章产品设计与开发工具,4.7制造与装配阶段,4.7.2六西格玛设计,P193)
六西格玛法六西格玛法旨在通过各种流程中的专门改进来减少业务和制造流程的变动,它包含DMAIC和DFSS。
关于DMAIC和DFSS他俩的目的以及内容是有区别的:
DMAIC 是为了改进现有流程使其输出能满足客户的需求。
而DFSS是为了设计新产品和流程以满足客户需求。
题干关键信息是最后一句话,问的是DMAIC的目的,显然只有A选项是符合的。
B选项的描述应该是质量屋方法的展开,与题干无关,不选。
C选项是产品设计过程由产品概念描述转化为产品设计规格,与题干无关,不选。
D选项应该是ATAR模型在特定情况下的运用,与题干无关,不选。
综上本题选A。
