Thanks for your comments. For the most part, I don't think we are in disagreement here (even if we are saying things in different ways). One of the ideas that animate this post is that we shouldn't always be looking for 'perfection' (or at least 'best practices') as the lens through which look for models and insights to help guide our own planning and implementation behavior. 'Lots of practice' -- and the ability to learn and improve as a result! -- seems to be what separates initiatives that do well from those that don't, no matter their starting points.
