The view and metaphorical analogy of an organization as a machine was the result of the only frame of reference available at that time, and is anchored in the conditions then prevalent, large numbers of un- or semi-educated people aggregating into centers clustered around factories. When the view is combined with what business organizations are designed to do -- take raw materials and convert them as quickly and efficiently as possible into commercial products that will make a profit -- the comparison of organization to machine is easily made and readily apparent. As in the new machines available during the industrial revolution, organizations can be seen as composed of many "parts" which are the individual people and/or business departments (milling, stamping, forging, assembly, etc.). Any of which can be changed, modified, or replaced individually or totally.
The hierarchical, pyramidal representation also coincides with the machine where one part is crucial (power source), diffusing downward through power shafts which turn various wheels (departments) with many cogs (people) that produce something. The metaphor of the machine is useful and appropriate in bureaucratic organizations where repetition and conformity is useful, and where the output is a standard homogeny.
