Chapter 1 Introduction to Operations and Competitiveness Prepared by Şevkinaz Gümüşoğlu Using different POM references
Production/Operations management (POM) is concerned with the production of goods, services and information. All business enterprises produce goods, services and information. They try to serve in the satisfaction of human need in one way. So production activities are the foundation of a nation’s economic system.
What Operations Managers Do? They plan, organize, staff, direct, coordinate the production/ operations What is Operations Management? design operations, and improvement of productive systems What is Operations? a function or system that transforms inputs into outputs of greater value What is a Transformation Process? a series of activities along a value chain extending from supplier to customer activities that do not add value are superfluous and should be eliminated 1-3
WHAT IS PRODUCTION& OPERATIONS SYSTEM A production/operations system is a configuration of resources combined for the provision of goods or services. A production/operations system is that part of the organization that exists primarily to generate and produce the organization products, i.e. goods or services..

What is the labor of division? The division of labour is the specialisation of cooperating individuals who perform specific tasks and roles. Historically, an increasingly complex division of labour is associated with the growth of total output and trade, the rise of capitalism, and of the complexity of industrialised processes. The concept and implementation of division of labour has been observed in ancient Sumerian cooperating individualstradecapitalismindustrialisedSumerian
Mesopotamian) culture, where assignment of jobs in some cities coincided with an increase in trade and economic interdependence.Mesopotamianeconomic interdependence In addition to trade and economic interdependence, division of labour generally increases both producer and individual worker productivity.
In contrast to division of labour, division of work refers to the division of a large task, contract, or project into smaller tasks — each with a separate schedule within the overall project schedule. Division of labour, instead, refers to the allocation of tasks to individuals or organisations according to the skills and/or equipment those people or organisations possess. Often division of labour and division of work are both part of the economic activity within an industrial nation or organisation.division of workdivision of work
James Watt was the most important person especially beginning the industrial revolution. Job shop production was organized in Whitney’s gun factory as the method of manufacturing in batches. Charles Babbage provided us too much contribution for management. Frederic Taylor is the father of management science.
Henry Ford begun job flow production in manufacturing which are called serialized production systems. http://www.youtube.com/swf/l.swf?video_id=S4KrIMZ pwCY http://www.youtube.com/swf/l.swf?video_id=S4KrIMZ pwCY
Harris gave us some important information about inventory control. Shewhart used the statistical theory for Quality Control (QC). Computer and Operations Research (OR) are used for business. Deeming and Juran presented us Total Quality Management (TQM). Toyota used pull system instead of push system (Just-in-Time JIT). Motorola developed Six Sigma Method for Quality Manegement Boeing devoloped & the other firms World Class Manufacturing
W HY STUDY PRODUCTıON / OPERATıONS MANAGEMENT (POM)? We study POM for four reasons: a. POM is one of the three major functions of any organisations, and it is integrally related to all the other business functions. All organisations market (sell), finance (account), and produce (operate), and it is important to know how the POM segment functions. Therefore, we study how people organise themselves for productive enterprise. b. We study POM because we want to know how goods and services are produced. The production function is the segment of our society that creates the products we use.
c. We study POM to understand what production/ operations managers do. By understanding what these managers do, you can develop the skills necessary to become such a manager. This will help you explore the numerous and lucrative career opportunities in POM. d. We study POM because it is such a costly part of an organisation. A large percentage of the revenue of most firms is spent in the POM function. Indeed, POM provides a major opportunity for an organisation to improve its profitability and enhance its service to society.
The production and operations management is also used to denote the wide scope of application. Production operations management or, more simply, operations management include the service industries as well.
Ch 1 - 2 The Operations Function & The Field of Operations management Operations as a transformation process Operations as a basic function Operations as the technical core OM is defined as the design, operation, & improvement of the production systems that create the firm’s primary products or services. OM is fuctional fields of business with clear line manegement responsibilities.
This point is important because operations management is fruquently confused with Operations Research(OR) & Management Science(MS) and Industrial Engineering(IE). This sitiuation is need to support the application of QM to decision making in all fields.
OM is related with other business function like Management, Finance, & Accounting and etc. Because; –Accountants need to understand the basic of Investment Management, Capital Uti.&labor standarts to develop accurate cost data, perform audits & prepare financial reports. Cost Accountants in particular must be aware of how JIT and CIM work. –Finance managers can use investment& capital. Concepts to judge the need for capital investment, to forecast cash flow, & to manage current assests. Make or buy,plant expansion etc.
–Marketing specialists need to understand what operations can do relative to meeting customer due dates, product customization,& new product introduction. So Marketing & Operations Management have overlapping interests. –Human Resource Managers must know how jobs are designed, relationship between standart & incentive plans, & the types of production skills required of the direct workforce. –Management Information System (MIS) specialist often install OI systems that they themselves design or that are developed as off-the-shelf software by computer companies. As a major business application of computers in POQC.
–Everybody know that entrepreneurs often fail because they run out of working capital due to poor production planning and inventory management. Because of all these reason The firm’s Corporate Strategy is based on the corporate mission and in essence reflects how the firm will plans to use all its resources and functions to gain competitive advantage. The Operation Strategy specifies how the firm employ its production capabilities to support its corporate strategy. Within the operations function, management decisions can be divided into three broad areas: Strategic (long term) decisions : Tactical (intermediate decisions), Operational planning, control (short-term) decisions.
We have omitted in the notes the theoretical treatments and have concentrated on providing an easy-to-read, easy-to- understand treatment of the basic POM knowledge. In other words, our aim was to give students a solid understanding of the analytical tools necessary to solve production/operations problems. Finaly the purpose of production/operations is to satisfy people’s wants. And then we can define; PO System.
Operations as a Transformation Process Copyright 2011 John Wiley & Sons, Inc. 1-32 INPUT Material Machines Labor Management Capital TRANSFORMATION PROCESS OUTPUT Goods Services Feedback & Requirements
To produce goods and services various form of inputs are brought together in a transformation system.
R ESOURCES IN P RODUCTION /O PERATIONS S YSTEMS Managers in production and operations functions practice production/operations management. They do not practice behavioural science, quantitative methods or systems analysis, although they utilise these underlying disciplines. Likewise doctors do not practice biology, although they know how to use biological methods. While methodologies are certainly important, they are not essence of POM. PO managers are principally concerned with the use of physical resources;
Therefore we shall take a physical view of PO systems and concentrate on the physical resources used by the system which for convenience will be categorized as follows: Materials, i.e. the physical items consumed or converted by the system, e.g. raw materials, fuel, indirect materials. Capital, i.e. the physical items equipment and facilities, used by the system, e.g. plant, tools, vehicles, buildings. Human Resources, i.e. the people, workers and managers, who provide or contribute to the operation of the system, without which neither machine nor materials are effectively used.

We know real production problems began to physical production in the industrial revaluation. For this reason the knowledge about the field is known as production management. And then service business came in to our life So it has been seen that production management concepts and tools could be easily applied in all types of enterprises.
In 1940 Operations Research Techniques were developed and computer became economical. Computers come along to give managers up-to-the- minute information about markets costs, production levels and inventories. Machines with linked computers that are responsible for changing them over from one job to another. Manufacturers began installing logic units in equipment.
Computers are the driving force in the long-wave changeover of manufacturing technology. The grouping of computer-controlled machines and development of industrial robots have now given production systems the flexibility to receive and respond to on line information. With robots, flexible manufacturing can deliver customized products.
Robots and flexible production system are reducing the demand for low skilled direct labor. Offsetting this surplus of untrained workers is the growing need for more technically trained control and maintenance personnel.
Retraining is needed to prepare low-skilled workers for the emerging more sophisticated fields of work. Learning organization is new important concept to manufacturing. Business of the future will be more active involving specialty items (high-tech metals) and advanced information and communications services.
A change in management technology is necessary. Because traditional old approach do not provide appropriate support for new kind of manufacturing systems developed often The mid 1980, New manufacturing technology cannot be used without changes in management technology.
By the year 2020, about 85-90 percent of workforce will most likely be engaged in nonmanufacturing activities. Now about 70 percent of world workforce are engaged in service activities. High-technology system (e.g. electronic, fiber optics, laser) will play en major role.
In the 1940s, nobody have guessed how much manufacturing technology would change by 1990. Using robots, in 1990 factories doubled output-with half as many blue-color workers-to match growth in consumer fueled by sharply lower costs and higher quality. We can say some new concepts: Smart Customer Smart factories “Smart Customers interact with smart factories to help design the goods and services that they want.”
The idea that the customer can use computer to intent out directly with the production process was suggested by Chrysler Coo. in 1960. Customers in 1990 dial the production process directly on their computerized telephones to set down their design specifications. For the particular varieties of the company’s product that they desire to purchase.
Companies have invented a variety of competing and co-operative strategies to fit their own unique situations. Some of the competitive approaches are continuous quality improvement, being first bringing new products to market increasing the firm’s value-added and so on. Competition relentlessly seeks to improve both manufacturing and management.
Technology and telecommunication have been brighten some new approach for business. Now we can write these two points as follows: 1) Changes in manufacturing technology- the use of information networks by people and computer driven equipment. 2) Changes in management technology- the managing of manufacturing technology for example JIT and Kanban, reengineering etc. As in all of these waves of technological change, there are new tactical production concepts and new strategic concepts that must be understood for the strategic production planning.
Because of global changes in business there are five main elements that capture the changing in manufacturing that are taking place. 1) There are fewer workers on the line. 2) There are fewer supervisors for the line. 3) More smart machines. 4) More workers engaged in planning systems. 5) More workers designing hardware and software.
So it is necessary a manufacturing system that receives all in formation that exists in the company, on-line and immediately. It has decision making competence based on all relevant information. So we can say that to use Computer Integrated Manufacturing (CIM) will be too important for us.

It seems that flexible manufacturing or World Class Manufacturing (WCM) created the need for top management that was oriented towards putting it all together with the systems viewpoint. We know, some enterprises is related with one or two or more business activities.
On the other hand production activities are related with all of them. Finally production/operations management is the study of the principles and quantitative and qualitative tools of decision making in periodic tasks of selecting, designing and updating a productive system and continual tasks of operating controlling and maintaining it.
