He uses the metaphor of sheep herding vs shepherding. While I was reading, it came to my mind this picture. I think that this picture is interesting, because cattle shepherding is less common.
On the picture, Don Guillermo Lebrón is leading cattle to the next paddock (grass land) in a case of Voisen Managed intensive grazing at “La Parcela”, in Félix Pérez Cardozo,
This way of leading cattle is a result of training, with rules and rituals that are followed daily, for instance, going to the water tank or moving to the next paddock.
Of course the analogy has its limits, but comparing the traditional cattle management with this one gives a contrast as strong as the one between traditional supervisor/Project Management and HPT leadership. (Spanish)
