The origin of management
Difficulties arise in tracing the history of management. Some see it (by definition)
as a late modern (in the sense of late modernity) conceptualization. On those terms it
cannot have a pre-modern history, only harbingers (such as stewards). Others, however,
detect management-like-thought back to Sumerian traders and to the builders of the
pyramids of ancient Egypt. Slave-owners through the centuries faced the problems of
exploiting/motivating a dependent but sometimes unenthusiastic or recalcitrant
workforce, but many pre-industrial enterprises, given their small scale, did not feel
compelled to face the issues of management systematically. However, innovations such
as the spread of Arabic numerals (5th to 15th centuries) and the codification of doubleentry
book-keeping (1494) provided tools for management assessment, planning and
control.
Given the scale of most commercial operations and the lack of mechanized recordkeeping
and recording before the industrial revolution, it made sense for most owners of
enterprises in those times to carry out management functions by and for themselves. But
with growing size and complexity of organizations, the split between owners
(individuals, industrial dynasties or groups of shareholders) and day-to-day managers
(independent specialists in planning and control) gradually became more common.
