With the advent of the machine industry this pecuniary rating of efficiency gained a new impetus and brought new consequences for technology as well as for business enterprise. Typically, the machine industry runs on a large scale, as contrasted with handicraft, and it involves a relatively wide and exacting division of labour between workmanship and salesmanship. Under the conditions of large ownership implied in this modern industrial system the workmen no longer have, or can have, the responsibility of the pecuniary management of the industrial concern; on the other hand the same conditions of large ownership and extensive business connections require the businessmen in charge to delegate the immediate oversight of the plant and its technological processes to other hands, and to devote their own energies to the pecuniary management of the concern and its transactions. Hence it follows that as the machine system and the highly specialised business enterprise that goes with it reach a larger scale and a higher degree of elaboration the businessmen in charge are, by training and by progressive limitation of interest, less and less competent to take care of the technological exigencies of the machine system. But at the same time the discretion in technological matters still rests in their hands by force of their ownership. So that, while the responsibility of technological discretion still rests on them, and cannot be fully delegated to other hands, the exigencies of business enterprise and of the training which it involves will no longer permit them to meet this responsibility in a competent fashion.
