In the early day of the post-war corporation, the question of purpose hardly arose. Companies like DuPont had been given an obvious reason to invest in the production of smokeless gunpowder by the Second World War, and at its end they found themselves in possession of a lot of capital equipment and chemical know-how. They went out looking for new things to do with cellulose and petrochemicals because it would have been strange not to. As they grew more complicated, they had to reorganise their corporate forms and management structures; academic writing in management was really just catching up with the things that engineers and accountants were inventing out of necessity.
