Integration of Manufacturing and Services

Integration of Manufacturing and Services More recently manager have recognized the importance of both manufacturing and cervices and the need to integrate the two primary objective of this text is to emphasize integrate integration Companies that want to succeed as world-class operations therefore must devote resources to both areas In addition production and service must be compatible with each other and stra

OM in Services

OM in Services As stated earlier Theodore Levitt was probably one of the first to demonstrate how many of the concepts and tools that had been developed for manufacturing operations could also be applied to service operations. By using these tools  services also could realize many of the inefficiencies of operation that had previously been limits to manufacturing. McDonald’s provided several good example

The Marriage of OM and Information Technology

The Marriage of OM and Information Technology Today as we noted earlier information technology (IT) plays a critical role in the design and management of production processes  Business process reengineering  supply chain management and sophisticated tools for systems integration such as SAP all defined later in the book require integrated solutions that marry OM and IT.  To illustrate a survey of consulting

OM Emerges as a Field

OM Emerges as a Field In the late 1950 and early 1960 scholars began to write texts dealing specifically with operations management as opposed to industrial engineering or operations research. Writers such as Edward Bowman and Robert Fetter Analysis or Production and Operations Management 1957 and Elwood S. Buffa  Modern Production Management CI 961 clearly noted the commonality of problems faced by all manufac

Operations Research World War II with its complex problems of logistics control and weapons systems design provided the impetus for the development of the interdisciplinary mathematically  oriented field of operations research. Operations research (OR) brings together practitioners in such diverse fields as mathematics psychology and economics. Specialists in these disciplines customarily form a team to structu

Hawthorne Studies

Hawthorne Studies Mathematical and statistical developments dominated the evolution of operations management from Taylor’s time up to around the 1940. One exception was the Hawthorne studies conducted during the late 1920 and early 1930 by a research tears from Harvard Business School and supervised by the sociologist Elton Mayo. These experiments were designed to study the effects of certain environmental

Scientific Management

Scientific Management This all changed with the introduction of scientific management at the beginning of the twentieth century. Although we could claim that operations management has existed since the dawn of civilization scientific management was probably the first historical landmark in the field in that it represented for the first time a systematic approach to manufacturing. This concept was developed by F

Historical Development of OM

Historical Development of OM Prior to 1900 Up through the end of the eighteenth century agriculture was the predominant industry in every country. Manufacturing as we  now it today did not exist. Items were usually custom made by skilled artisans who spent many years in apprenticeship learning every facet of how to make a good or provide a service. No two products were ever these. For many products trades or gu

Job Opportunities in Operations Management: Relating OM to Other Business Functions

Job Opportunities in Operations Management: Relating OM to Other Business Functions Exhibit  lists some of the line and staff jobs that usually fall within the operations function. There are more staff specializations in manufacturing than in services because of the focus on materials management and control. Operations Management is a required course in many business schools. not only because it deals with th
