Manufacturing
Manufacturing is the production of merchandise for use or sale using labour and machines, tools, chemical and biological processing, or formulation. The term may refer to a range of human activity, from handicraft to high tech, but is most commonly applied to industrial production, in which raw materials are transformed into finished goods on a large scale. Such finished goods may be sold to other manufacturers for the production of other, more complex products, such as aircraft, household appliances, furniture, sports equipment or automobiles, or sold to wholesalers, who in turn sell them to retailers, who then sell them to end users and consumers.
Manufacturing
Mechanical engineering may be defined as the manufacture, installation, and repair of all kinds of machinery (including machine tools), prime movers and boilers, and engines.

Production
To those who clamor, as many now do, "Produce! Produce!" one simple question may be addressed:—"Produce what?" ...What can be more childish than to urge the necessity that productive power should be increased, if part of the productive power which exists already is misapplied? Is not less production of futilities as important as, indeed a condition of, more production of things of moment? ... Yet this result of inequality ... cannot be prevented, or checked, or even recognized by a society which excludes the idea of purpose from its social arrangements and industrial activity.
R. H. Tawney, The Acquisitive Society (1920), p. 39.
