Lec Notes © Stevenson, McGraw Hill, 2007- Assoc. Prof. Sami Fethi, EMU, All Right Reserved. Introduction; Chapter1 Basic Concepts Input- Materials, labour, information, technology, equipment, legal constraints, government regulations etc.... What type of skill do the employees need? What type of materials does the firm need? Value-Added Activities- Performed with tools machines, techniques, human skills etc....i.e. Processing. How will the firm use its resources to produce its products/ how can the firm improve its operations? Output- Good and services. what are their needs/what sort of products will be produced? 7 MGMT 405, POM, 2010/11. Lec Notes © Stevenson, McGraw Hill, 2007- Assoc. Prof. Sami Fethi, EMU, All Right Reserved. Introduction; Chapter1 Value-added Value-added is the difference between the cost of inputs and the value or price of outputs. In non-profit organization, value-added of output is their value to society. The greater the value-added, the greater the effectiveness of these operations (i.e. High way construction, state school construction etc...). In profit organization, value-added of output is measured by prices that customers are willing to pay for those goods and services. Firms use the money generated by value-added for research and development, worker salaries and profit. The greater the value-added, The greater the amount of funds available for these purposes. 8 MGMT 405, POM, 2010/11. Lec Notes © Stevenson, McGraw Hill, 2007- Assoc.

Lec Notes © Stevenson, McGraw Hill, 2007- Assoc. Prof. Sami Fethi, EMU, All Right Reserved. Introduction; Chapter1 Why Product Packages? Because there are relatively few pure goods and pure services and therefore companies sell Product packages for their own benefit or interest. Product packages are a combination of goods and services. Product packages can make a company more competitive. 10 MGMT 405, POM, 2010/11. Lec Notes © Stevenson, McGraw Hill, 2007- Assoc.

Tangible Act Manufacturing and Service are often different in terms of what is done but quite similar in terms of how it is done. For example, manufacturers decide what size factory needed and service organizations must decide what size building is needed. Manufacturing and Service differ cause manufacturing is goods-oriented and service is act-oriented. 13 MGMT 405, POM, 2010/11. Lec Notes © Stevenson, McGraw Hill, 2007- Assoc.

Introduction; Chapter1 Historical Evolution of Operations Management Industrial revolution (1770’s) in England Scientific management (1911) Mass production Interchangeable parts Division of labor Human relations movement (1920-60) A psychologist focusing on human factor in work-tiredness and motivation. Decision models (Harris 1915-inventory model, 1960-70’s) The factory movement was accompanied by the development of several quantitative techniques. After ww II-the importance of military and manifucturing sectors, the models of forecasting, inventory management, project management were developed. Influence of Japanese manufacturers JIT production, quality revolution, continual improvement etc. MGMT 405, POM, 2010/11. Lec Notes 24 © Stevenson, McGraw Hill, 2007- Assoc. Prof. Sami Fethi, EMU, All Right Reserved. Introduction; Chapter1 The evolution of POM Production of goods remained at a handicraft level untill the Industrial revolution took place. In 1764 (1770s), the Industrial revolution began and James Watt invented the steam engine and advanced the use of mecanical power to increase productivity. Eli Whitney (1798) found out and introduced the concepts of standardised parts and interchangeable parts. He then developed musket system because the type of muskets were handcrafted-he produced 10000 muskets by using the concept of interchangeable parts. By using the same concept, he allowed the manifacture of firealarms, clocks, watchs, sewing machines etc.. Soon after, by conducting the concept of steam engine, Richard Trevithick (1802) invented the first train and Richard Fulton (1807) invented the first steam boat. 25 MGMT 405, POM, 2010/11. Lec Notes © Stevenson, McGraw Hill, 2007- Assoc. Prof. Sami Fethi, EMU, All Right Reserved. Introduction; Chapter1 The evolution of POM The first steam boat and the first train indicate a long stream of application in which human anad animal powers were replaced by engine power. The Industrial revolution was the transformation of a society from peasant and local occupation into a society with world wide connections in terms of great use of machinery and largescale commercial operations. This is the first step of factory system. This system replaced the traditional production system by the concept of mass-production by bringing together large numbers of semi-skilled workers. Adam Smith’s ‘The wealth of nations’ (1776) pointed out the importances and advantages of the division of labor where the production process was broken down into series of small tasks and each performed by a different worker. MGMT 405, POM, 2010/11. Lec Notes 26 © Stevenson, McGraw Hill, 2007- Assoc. Prof. Sami Fethi, EMU, All Right Reserved. Introduction; Chapter1 The evolution of POM With aid of the concept of the division of labor: Workers who continually perfomed the same task, they would gain skill and experience. Saving time or avoiding lost time due to changing jobs. Workers’ concentration on the same job increased would lead to the development of special tools and techniques for faster and easier task. Specialization jobs and division of labor began to take place. A prominent mathematician and engineer Charles babbage (1832) promoted an economic analysis of work and pay on the basis of skill requirement. In the earliest days of manufacturing, goods were produced using craft production-highly skilled workers conducting simple, flexible tools to produce small quantities customized goods . 27 MGMT 405, POM, 2010/11. Lec Notes © Stevenson, McGraw Hill, 2007- Assoc. Prof. Sami Fethi, EMU, All Right Reserved. The evolution of POM Introduction; Chapter1 Frederick Taylor (1911) who is often referred to as the father of scientific management, published ‘the priciples of scientific management’. This helped to achieve wide tasks in industry. Frank Gilber (principles of motion economy), Henry Gantt (schudeling and charts design for system) and Herrington Emerson (organizational efficiency) used Taylor’s ideas to improve the system of operation and production management. Influence of Japanese manufacturers JIT production, quality revolution, continual improvement etc. Using the concept of JIT production, Japanese manufacturers changed the rules of production from Mass Production to Lean Production. Lean production prizes flexibility rather then efficiency, as well as quality rather than quantity. This indicates the first step of ‘Era of Industrial globalization’. MGMT 405, POM, 2010/11.

Introduction; Chapter1 School of Management The process school of management was developed by Henry Fayol in 1900 management can be viewed as a continuous process the function of planning, organizing and controlling The behavioural school of management was developed by Elton Mayo in 1920 human relation movement on production output Productivity depends not only on the physical environment but also on social norms and personal feelings (i.e. Western Electric’s Hawthorne plant) 30 MGMT 405, POM, 2010/11. Lec Notes © Stevenson, McGraw Hill, 2007- Assoc. Prof. Sami Fethi, EMU, All Right Reserved. Introduction; Chapter1 School of Management The quantitative school of management is concerned with decision making, mathematical modeling as well as system theory represents a productive system In 1915, Harris developed an Economic Order Quantity model for inventory management In 1931, Shewhart developed a Quantity decision model for use in Statistical quality control work In 1947, George Dantzing developed PERT/CPM In the late 1950s and early 1960s Edward Bowman, Robert Fetter and Elwood Buffa developed the concept called Modern poduction Management As computers became available in the 1950s, the power of opeartions research was multiplied 31 MGMT 405, POM, 2010/11. Lec Notes © Stevenson, McGraw Hill, 2007- Assoc. Prof. Sami Fethi, EMU, All Right Reserved. Introduction; Chapter1 School of Management The School of Modern Management In the late 1960s, MRP and CPR were introduced by Joseph Orlicky and Oliver White In the late 1970s, MRP II, JIT, TMQ and KANBAN systems were developed the School of Modern Management includes the system and the contingency approaches. these are also called new contemporary management approaches the system approach points out that an organization has interdependent factors as such individuals, status, motives, goals etc and must work together the contingency approach reveals that organizations are different so different and changing cases need to conduct different approaches and techniques in reaching a solution 32 MGMT 405, POM, 2010/11.
