Great post, Harold - and, by extension, Tim too. Given ideas relating to continuous improvement, learning and application of new knowledge, the notion of 'best practice' has always truck me as an odd one. It's like the Holy Grail, forever out of reach. I think most, in the spirit of learning by doing, should start with 'practice' or, at most, 'good practice'. By adapting such practices to their own environments and work context they will evolve it into something slightly different, picking up the tacit knowledge along the way.
