Industrial Organization, Continued.
Division of Labour.
The Influence of Machinery 1.The first condition of an efficient organization of industry is that it should keep everyone employed at such work as his abilities and training fit him to do well, and should equip him with the best machinery and other appliances for his work.We shall leave on one side for the present the distribution of work between those who carry out the details of production on the one hand, and those who manage its general arrangement and undertake its risk on the other; and confine ourselves to the division of labour between different classes of operatives, with special reference to the influence of machinery.In the following chapter we shall consider the reciprocal effects of division of labour and localization of industry; in a third chapter we shall inquire how far the advantages of division of labour depend upon the aggregation of large capitals into the hands of single individuals or firms, or, as is commonly said, on production on a large scale; and lastly, we shall examine the growing specialization of the work of business management.
Everyone is familiar with the fact that "practice makes perfect," that it enables an operation, which at first seemed difficult, to be done after a time with comparatively little exertion, and yet much better than before; and physiology in some measure explains this fact.For it gives reasons for believing that the change is due to the gradual growth of new habits of more or less "reflex" or automatic action.Perfectly reflex actions, such as that of breathing during sleep, are performed by the responsibility of the local nerve centres without any reference to the supreme central authority of the thinking power, which is supposed to reside in the cerebrum.But all deliberate movements require the attention of the chief central authority:
it receives information from the nerve centres or local authorities and perhaps in some cases direct from the sentient nerves, and sends back detailed and complex instructions to the local authorities, or in some cases direct to the muscular nerves, and so co-ordinates their action as to bring about the required results.(1*)The physiological basis of purely mental work is not yet well understood; but what little we do know of the growth of brain structure seems to indicate that practice in any kind of thinking develops new connections between different parts of the brain.
Anyhow we know for a fact that practice will enable a person to solve quickly, and without any considerable exertion, questions which he could have dealt with but very imperfectly a little while before, even by the greatest effort.The mind of the merchant, the lawyer, the physician, and the man of science, becomes gradually equipped with a store of knowledge and a faculty of intuition, which can be obtained in no other way than by the continual application of the best efforts of a powerful thinker for many years together to one more or less narrow class of questions.Of course the mind cannot work hard for many hours a day in one direction: and a hard-worked man will sometimes find recreation in work that does not belong to his business, but would be fatiguing enough to a person who had to do it all day long.
Some social reformers have indeed maintained that those who do the most important brain work might do a fair share of manual work also, without diminishing their power of acquiring knowledge or thinking out hard questions.But experience seems to show that the best relief from overstrain is in occupations taken up to suit the mood of the moment and stopped when the mood is passed, that is, in what popular instinct classes as "relaxation." Any occupation which is so far business-like that a person must sometimes force himself by an effort of the will to go on with it, draws on his nervous force and is not perfect relaxation: and therefore it is not economical from the point of view of the community unless its value is sufficient to outweigh a considerable injury to his main work.(2*)2.It is a difficult and unsettled question how far specialization should be carried in the highest branches of work.
In science it seems to be a sound rule that the area of study should be broad during youth, and should gradually be narrowed as years go on.A medical man who has always given his attention exclusively to one class of diseases, may perhaps give less wise advice even in his special subject than another who, having learnt by wider experience to think of those diseases in relation to general health, gradually concentrates his study more and more on them, and accumulates a vast store of special experiences and subtle instincts.But there is no doubt that greatly increased efficiency can be attained through division of labour in those occupations in which there is much demand for mere manual skill.
Adam Smith pointed out that a lad who had made nothing but nails all his life could make them twice as quickly as a first-rate smith who only took to nail-making occasionally.
