Correlation Analysis ? A statistical analysis to investigate / measurement of association between two variables (X, Y) is called analysis. ? Correlation tells you the trend of Y when X value increase/decrease. ? Correlation Analysis using Scatter Diagram Analysis. ? Correlation coefficient indicates closeness of a relationship between X and Y. ? Regression Analysis (1) Y = f (x1, x2, x3,… ) Status and characteristics of a process Modeling Mathematical equation X Y ? Regression Analysis (2) ? Types of Regression Model ?

In analysis step, potential X’ s were identified with a possible prioritization as to their importance in controlling Y. Improve step provides tools to explore and uncover the vital X’ s and how much impact each X has on the response Y. ? One of the major tools used for both exploration and confirmation of the effect of X’ s on the Y’ s is experimental design (DOE). By experimentally manipulating the independent variables, DOE provides an efficient and economical means for reaching valid and relevant conclusions about a process. ? Types of Experimental Design Screening ◎ Full factorial ◎ 2K factorial ◎ Fractional factorial Optimization ◎ Multilevel experiments ◎ Composite design ◎ Response surface method ? I2 Formulate Optimum Model ? The vital few important X’ s were identified and characterized in I1. The tools in I2 follow a methodology for establishing levels of these X’ s that will provide improved performance for the Y. . DMAIC Methodology 5 Stages DMAIC Methodology and Statistical Tools ?
