HISTORICAL EVOLUTION OF PRODUCTION AND OPERATIONS MANAGEMENT



      Progressing through a series of names - manufacturing management,
 production management, and operations management - all of which 
describe the same general discipline, the evolution of the term reflects
 the evolution of modern operations management. The traditional view
 of manufacturing management began in the eighteenth century when 
Adam Smith recognized the economic benefits of specialization of labor.
 He recommended breaking jobs down into subtasks and reassigning
 workers to specialized tasks in which they would become highly skilled 
and efficient. In the early twentieth century, Frederick. W.Taylor implemented
 smith’s theories and crusaded for scientific management throughout the vast 
manufacturing complex of his day. From then until about 1930, the traditional
 view prevailed and many techniques we still use today were developed.
       Production management became the more widely accepted term from the
 1930s through the 1950s.As Frederick Taylor’s  work became more widely known,
 managers developed techniques that focused in economic efficiency
 in manufacturing. Workers were “put under a microscope” and studied 
in great detail to eliminate wasteful efforts and achieve greater efficiency.
 At this same time, however, management also began discovering that
 workers have multiple needs, not just economic needs. Psychologists,
 sociologists, and other social scientists began to study people and
 human behavior in the work environment. In addition, economists,
 mathematicians, and computer scientists contributed newer, more 
sophisticated analytical approaches.
         With the 1970s emerged two distinct changes in our views.
 The most obvious of these, reflected in the new name ---operations
 management -------was a shift in the service and manufacturing sectors
 of the economy. As the service sector became more prominent, the
 change from “production” to “operations” emphasized the broadening
 of our field to service organizations. The second, more subtle change
 was the beginning of an emphasis on synthesis, rather than just 
analysis, in management practices. Spearheaded most notably by 
Wickham skinner, American industry was awakened to its ignorance
 of the operations function as a vital weapon in the organization’s 
overall competitive strategy.
