Many enterprises interested in agile adoption believe that their strategy should consist of sending a technical leader or manager to a training course and then having him or her take over a project (of course, there are also those who try to "save" money and buy a book on agile in replacement of training). But if you were to ask executives from companies that have succeeded in migrating to agile, the feedback would be not to cut corners, but to take the necessary training and get coaching.
