6S DMAIC: Measure

Image
After we define the problem, we need evidence to support that it wasn’t just a freak accident. If odds are that it’ll never happen again, we won’t need to anything, right? In daily life, we are conditioned by habit; in diet, sleep, work, stress, and so on. When something unusual happens, it raises alarms that something might be wrong. In manufacturing engineering, data can be tracked using Statistical Process Control (SPC). Operators and equipment records process data of test, measurement, and yield. When the process is automated, a large database of “normal” data can be determined. Once a baseline is established, there are still allowable tolerances that are expected from noise and variation. An example SPC chart. When data exceeds the UCL (3 sigma above mean), there needs to be action! As expected from Six Sigma: any data point that crosses beyond the Lower Control Limit (LCL) or Upper Control Limit (UCL) should be measured. With these deviations compared against a long history of da...

Asia Trip Day 8: Osaka for Kobe Beef (12/26/17)

Sleeping on the Shinkansen The next morning we headed over the station to take the Yamanote line back to Shinjuku station to catch the Shinkansen to Osaka. On the first day, we made seat reservations at the JR office. The Hikari Shinkansen has reserved and non-reserved seats, and obviously it would be the safest to get a reservation. We selected a non-peak time (around 8:30 am), so there weren’t any large crowds. The ride from Tokyo to Osaka was about 1.5 hours. Xuezhu picked up lunch bento boxes from within the station. Some toilets in Osaka. The faucet would run after flushing We arrived at Shin-Osaka station, and transferred to the Midosuji line to arrive at Namba station. All of the points of interest for Osaka were within walking distance of each other. We dropped our luggage at our hotel, which was a typical hostel (HostelQ).  I was feeling pretty fatigued because of the long day yesterday and the fact that I didn’t get too much sleep the night bef...

Asia Trip Day 12: Day of Rest (12/30/17)

Look at the massive forearms on this guy Xuezhu and I were physically sore from the trip in Japan, primarily in the traps, shoulder, and back from walking around all day wearing our heavy backpacks. She took me to a massage parlor, which had several blind masseurs. The building was old and a little messy. They took us to the back through several doors into a private room. Xuezhu had a blind woman to massage her, but I got a normal guy. This was my first massage, and it was quite brutal. My masseur was super strong, as evidenced by his massive foremans. He really dug into my muscles, and it felt like he was trying to crush them. It was the most agonizing when he was working on my traps and calves. The whole body massage lasted about an hour, and after that I felt battered and bruised in a different way. Mushroom! Mushroom! After the massage, we met with her dad at a restaurant specializing in mushroom hot pot. Since I was still recovering, they wanted to take me somewher...
