"The transport mechanism, the technology, is only half of the formula. The other half is understanding learning and teaching. Traditional training people don't necessarily have the IT background. IT people don't have what the training people have, which is a pretty good knowledge base about how to teach people and how people learn. So, what's emerging right now are some newer credentials that sort of marry those two. There are two things now that may move you up the management ladder. One is a degree in a field that marries the two. The other is, of course, job experience. The problem is that this stuff is expanding fast, and there's not a large pool of people with a lot of experience. Therefore, the credentials are becoming more important."
