>The fact that only a very few people in the world can be successful with the things that make a concert pianist successful does not mean that concert pianists have failed. Or does it mean they have failed at making a guide? If you have a guide 'how to be a professional concert pianist' and people who faithfully follow it only have a 1 in a 1000 chance of succeeding, perhaps it is a bad guide. Now, maybe everything in the guide is necessary, but it isn't sufficient. It may also be the best guide around, as every other has a success rate of 1 in 10,000 or worse. However that doesn't mean it is a successful guide. It is still failing to capture something that is needed to become a successful guide that can be spread to the masses. If it is guide for how a successful pianist can become even better, then perhaps it is a problem of too many people thinking themselves successful pianist when they aren't. So maybe what we need is to better focus on identifying which organizations aren't mature enough to adopt something like XP so they stop trying out a path that will fail because they aren't ready for it.
