“Rather than theorize about productivity in the abstract, he visited working factories—mostly small at that time—whose owners were putting an altogether new concept into practice. The first chapter of The Wealth of Nations is entitled “Of the Division of Labour.†When he visited a pin factory, Smith discovered that no fewer than eighteen separate operations were involved in fabricating a simple pin. And his insight, based on practical observation, was that productivity could be enormously increased if each worker did just one or two of those operations instead of all of them. Damrosch, Leo.
