If someone has a technical issue, they could have someone else assist them with the issue, or they could also have someone assist them by teaching them how to solve that issue. This will further increase their technical knowledge, and if more people are taught, less people would have that same issue. This also applies to training on something new. The more people learn how to use something, the better. The most important thing I learned about training is that it is a necessary and quick way to help teach people who are less knowledgeable about the subject.
