DOE & missions

It's a long day today. Unlike working, need to be more focused and concentrated. Most of all, need to learn soooo many  things. Yesterday a very wise man told me that he learned amazingly amount of knowledge when he did his master, school education totally opened his eyes. And now I'm feeling the same. Needless to say, there's always a lot to learn and discover in our lifetime, but sometimes you just have to work hard to get the knowledge and be sensitive enough to even recognize it's around you.

You can easily be inspired if you notice some little details or knowledge, or even just random words that people say. You never know what you're gaining. Life's full of surprise. And I love surprises!

This morning, thanks to Jarrett helping me untie the knots in my head of all the unfamiliar statistics analysis. I learned a lot in the morning. Am very proud of myself. In the afternoon, thanks to my teammates, we had a fun practice and analysis on the data, I'm really glad that I learned something totally new. This is actually one of my goal that I'm looking to achieve from the courses -- challenges. I believe challenges bring out the potential of a person to achieve something greater than one ever expects.

Now I know Taguchi (basic concepts), and how to analyse or create a product using the arrays and the statistic methods. I also enjoyed as much when running the experiments and actually doing all the practices and exercises. That helps the whole learning process. Coz you gotta use it if you're learning it - like languages~

Learning how to make a robust products also rang a bell on me as well. If I want the business to be sustainable, I need to have strong products or services. People never say no to innovative products. Anything that's new, funky, practical, interesting, convenient, delicate, fancy..etc, the market is always wide open for it. And making a robust product not only interests the customer, satisfies them, and also surprises them. As I said before, I love surprises! So the product will at least have 1 customer -- me. :-)

So today, my favorite part is practicing the real data analysis plus product manufacturing process. Learning by doing is the best, what else you ask for? :-) And being able to realize what we can discover after analysing the data after the experiment also taught me a lot that making sure I do the same in the future. It's a very objective and practical method to apply to.

Anyways, time to jot down few things to remind myself for today -- ANOVA, DoE, Mean value analysis, Interaction analysis, Signal to Noise Ratio Analysis (difficult, but very useful) -- details see paper notes.

In statistics, analysis of variance (ANOVA) is a collection of statistical models, and their associated procedures, in which the observed variance is partitioned into components due to different explanatory variables.

Design of experiments, or experimental design, (DoE) is the design of all information-gathering exercises where variation is present, whether under the full control of the experimenter or not.

*** Thanks to the team and Ivan, attached pls find our data for the helicopter exercise!
