There are many examples of human endeavors that would not have ended well without training. Moon shots, marathon running, heart surgery and triple axles (not 100% sure what that is) are just a few that come to mind. But don’t just think of training as necessary only to achieve super human feats.
Training is one concrete way to maximize the value of your software investments, a more mundane but very worthwhile goal. It doesn’t matter what type of software it is, if users don’t use it (out of fear) or use it incorrectly, the investment will not pay off – aka, Failure. That failure can be avoided with well thought out training.text
