The man is obviously quite bright. Brighter than me I'm sure. His talks apply to plant production - producing something requiring quality control like a lamp or an auto part. Not relevent to customer service based or web based or even entertainment based businesses (intellectual property, etc.). He seems to be convinced that he himself is the sole, self enthroned revolutionary without whose work the world would be doomed to its "old ways" prior to his "groundbreaking" theory of constraints - critical "chain"(path). I'm sorry but i just don't get all the hype. He seems to drone on like some religious leader looking to found his own industrial hyper-productive cult. But it's chatter chatter chatter. I couldn't get past the fourth hour. Was highly turned off by his self aggrandizing and back patting. Skip it.
