With the continued acceleration of global economic integration, themarket competition is becoming increasingly fierce,and especially in theelectronics manufacturing industry. The major electronics brands are facingmore and more severe cost and supply challenges. Many of the companieswill strengthen to control and reduce the supply chain costs to enhance thecompetitiveness of their businesses when they are facing the challenges.

And I use part I as an example of application of DMAIC.Theprocess for the research is: identify the key defectsâ†'analyze the reason fordefectsâ†'find the solution for improvingâ†'continuous improvement. Inthe project we used MSA (Measurement System Analysis), ANOVA (analysisof variance), single factor experimental design and other related tools. Bythese tools, we try to optimize the process and find the best solution forprocess. We improved the yield from50%to91%and reduce the cost. Thesuccessful implementation of the project provided a reference to otherimprovement project for similar products. And also it can help other companyto implement the6Sigma.
