Optimizing Process Performance by Statistical Validation Technique

introduction

Optimization means efforts to achieve the desired outcome out of a process. Let us visualize a process. A process has an output (we refer to as Y-metric), and the output is made of many factors at the input side (we refer to these factors as Xs’). To get the Y-metric to a desired level or value means aiming Y-metric at the target. In order to make this happen, the X factors must be manipulated in such a way Y-metric will achieve the set target. Normally there is more than one combination of the X factors that can result from this. This course teaches the participants about optimizing a process input parameter – then selecting the most practical (and economical too) one. Sometimes we are investigating just one single X factor, but most of the time these X factors are investigated simultaneously.

The other key learning in this course is the process outcome validation. When improvements are made, we are actually touching the X factors, and the result in Y-metric is monitored in real-time. Participants will learn the two elements monitored in Y-metric – the movement of the average and the shift in the spread size. Statistical tests are used to check the significance of the process outcome at the optimized (improved) setting of X parameters. Participants will be taught to confirm the improvement effectiveness by statistical testing methods. Based on the statistical analysis a correct action can be planned to improve the process further.

 

Objective

Upon completion of this workshop, participants will acquire the knowledge and application skills to find optimized setting of process inputs to achieve optimum outcome. The participants shall be able to:
