How important were the topics of training, service and maintenance in your decision to use imos?
Despite the fact that imos was imported to our Japan's company in 2015, we didn’t spend many time on focusing studying it. As a result, we couldn’t use it efficiently. In 2018, we decided to bring imos back to the Vietnam factory. This time, we required three people to study imos for six months, and the result is that now eight people can use imos. However, no matter how deep we try to get it, there's still a lot we don't understand, so the tracking system is absolutely essential.
