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.

blog more

Two week of study the PIUSS has finished, and I haven’t made any entry on the blog, which I admit, is not a good sign for PIUSS results. All of us received our mark for our CBE, and now I think we all realised how important is blogging. Some of us may still think blogging is a hard thing to do, like me. Now it is the time to walk out our comfort zone, blog more with quality entries, then we can all get full marks for our reflective study part.


It is the learning process. We all knew that blogging contribute around 15% to our our score, but sometimes, lack of motivation or don’t know what to say, all these factors discouraged us from blogging. Till the recent CBE results, we see clearly what marks we got for our blog entry, undeniable fact. So time to change, time to improve the learning process. Let’s all blog more.
