Because it's a small-scale operation without proper systems, new employee "basic training" is really difficult, but I happened to find this lecture, and it was a great help. Just as the instructor said, there were many things that made you think, 'Do I really need to teach even this?' and though they are new hires, it's awkward to directly and openly teach such things. These were points of difficulty for the company, but I feel this lecture can resolve those issues, and that's what I liked most. If your workplace is experiencing similar issues, I highly recommend it.
