Lean: 5S Methodology

Before my mom left for work, she assigned various chores to me and my siblings. She wanted a nice clean house to return to after a long day of work. From these childhood chores, I learned good habits for maintaining cleanliness. A clean space not only looks nice, but makes everyday life easier: With the floors clear, you don’t worry about tripping over things With the tables clear, you don’t worry about knocking things over With the valuables in a special area, you don’t worry about losing them We’re all capable of great things, but we let distractions waste our time and focus. I’ve leafed through various self-help books and they all advice contemplating on what is truly important in our lives. After cutting out all the useless noise, we can focus on the important matters The common advice for improving work efficiency is having a clean work station, because a clear environment is a clear mind. If we know exactly where our tools and resources are, it becomes one less factor to consider...

6S DMAIC: Measure

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 18: Chinese Fried Chicken (1/5/18)

We returned to the massage parlor again to get another round of massages. Xuezhu was feeling some soreness in her traps and back, so she got a special massage. After the massage, they put a special carriage over her back. It held some smoldering logs, which heated up her back. There was a wooden lid covering them, but it could be opened or removed if it gets too hot.  We returned back to her parent's house for lunch. Her mother cooked for us vegetables with dried shrimp, and chicken with taro. The vegetables were very savory from the salty shrimp, and reminded me of a similar dish my mom makes. We then went to the mall area to get our haircut. Xuezhu usually waits until she visits China to get her haircut or colored, since its much cheaper than in US. We snacked at the KFC at the mall, because I wanted to try it out. Xuezhu told me that fast food restaurants like McDonald's, Pizza Hut, and KFC were considered to be really fancy when they were first in...
