### Taguchi

I think some of us find Taguchi is a difficult part for our PIUSS study, because of the statistical elements involved. To be honest, I don’t think it really involves that much statistics, even if it does, probably just some easy math calculations. And we all know in the real world, we don’t need to do those complicated Orthogonal Arrays calculations, nowadays, we have our computer which can help us to do the calculations.

Taguchi theory is mainly used as a way to improve process, not by simply tampering the process, but looking at all the elements involved in a process, and by altering one or two at a time to see if there is any difference in the end result, so we can see clearly what the most influential factors are. If we don’t look at the calculations involved, I think the concept is quite simple. By looking at the Interactions and Noise Factor, the process can be optimised.

Running the Taguchi theory in practice might be costly and time consuming, but the benefit of an improved process are endless.

1. that’s what I think about. We got computer to do all the calculation. That’s why I choose this as project. But now I am just so afriad I may be too innocent…

2. Guys we must not run away from the problem, we must find the root cause… we must improve our understanding in statistics… we must… we must….
