You would be on this screen to start your experiment design tasks as well as to perform the analysis of results.

[2] Experiment Design Options: Orthogonal Arrays This screen offers available orthogonal arrays that are used to design the experiments. Several 2, 3, and 4-level arrays are available to meet the needs based on the types of factors included in the study. [3] Main Effect Graph – Basic Analysis of Results This screen shows the main effects of factors in the study. Plots for a single factor or multiple factors can be displayed on the same screen. [4] Pie Chart of Factor Influences This screen shows the relative influences of the factor to the variation of results that is obtained after ANOVA. [5] Optimum Condition The optimum factor levels that produce the most desirable condition is shown on this screen. If desired, the most conservative performance can be estimated by altering the number of significant factors included in making the estimated performance. [6] Variation Reduction This plot shows the variation reduction expected upon implementation of the optimum condition in graphical form. The process capability indices like Cpk & Cp can also estimated from the computed data.
