A1 Set Up Improvement Goal ? In M3 the current product capabilities were defined. ? Step A1 provides the tools to define performance objectives. ? The purpose is to set objective to establish a balance between improving customer satisfaction and available resources. ? A1 step covers following topics: – Establish performance goals – Assess shortterm and longterm sigma in terms of measurement benefits (decrease in COPQ, increase in revenue) – Determine improvement direction by the gap analysis between goal and current level ? Paths to Performance Goals Performance Goals Process Improvement (Entitlement) Process Change (Breakthrough) Baseline Process Measurement ? Benchmarking Why Benchmark (1)?

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. ?
