    Productions and Management Amalgamated

    Production implies application of processes (technology) to raw materialsto add value to the desired product using the best method, without

    compromising on the preferred quality. There are three ways of Production:(i) Production by disintegration: By separating the contents of crude oil

    or a mixture, the desired products are produced. For instance the crude oilis disintegrated into various fuel oils. Similarly, salt production is also anexample for product produced by disintegration.

    (ii) Production by integration: In this type of production, differentcomponents of the products are conglomerated to get the desired product.In this process, physical and chemical properties of the materials usedmay be modified. Examples include: assembly of two-wheelers, four-wheelers and so on.

    (iii) Production by service: In this case, the chemical and mechanicalproperties of materials are enhanced without any physical change. For example, heat treatment of metals. In reality, a combination of theaforementioned methods is used. In general, production is the use of anyprocess or procedure designed to transform a set of input elements into aset of output elements, which have use value and economic value.Management refers to getting things done by the people, by means of planning,coordination, organizing, directing and controlling the activities to fulfil specifiedgoals, within the framework of consensual policies. At present, productionmanagers require scientific base along with personal tactics to manage the

    people working under his supervision to attain the desired objectives.Source : Compiled by author

    1.1 Introduction

    The word production immediately conjures up images of large rooms filled withmachines of every shape and size, materials of all hues and colours, and peopleworking to fulfil their targets. The coordination between all these Ms (i.e. man,machine, materials, money and method) is done by the sixth M, i.e., management.This is what production and operations management is all about. It is concerned

    with the production of goods and services and is responsible for ensuring thatthese operations are efficient and effective. In other words, production andoperations management is to manage the efforts and activities of people,equipment and other resources of the organization in order to change raw materialinto finished goods and services.

    Production and operations involve the conversion of input into outputthrough a transformation process. In the early days production involved theprocesses followed for mass production of tangible goods. As the complexitiesof business grew, management of the systems responsible for productionbecame essential. Later, even services began to be produced or rendered.These were intangible. So some principles were needed which could encompassthe entire system that produced a commodity or delivered a service. It wasfound that the same principles could be effectively applied in the managementof processes that produced goods as well as those that produced services.This is production and operations management.

    control, organizational behaviour, safety management and maintenancemanagement, etc. So production and operations management deals with theconcepts and principles that are employed by organizations to make themefficient and effective. This unit introduces the concept of production managementthat uses the decision-making tools of operations research and the principles of industrial engineering, quantitative techniques, organizational behaviour and others.

    Objectives

    After studying this unit, you should be able to: discuss the history of production management define production management describe the production process analyse production as the heart of an organization list the objectives of production explain the scope of production interpret the importance of technology in production

    1.2 History of Production and Operations Management

    Before learning further, it is important to take a look at the history of productionand operations management. This will help you to understand that technology isthe backbone of all production functions.

    1.2.1 Industrial Revolution Era

    The Industrial Revolution of Great Britain during the late eighteenth century broughtabout extensive mechanization of production systems. It resulted in a shift fromhome based production to large scale production outside the home. Equipmentwere created that could produce in large quantities. Workers reported to a

    supervisor, who planned the work and issued orders to workers. Many inventionssuch as James Watts steam engine, Jenny Cartwrights power looms andMaudslays cutting lathes, etc., contributed to the Industrial Revolution.

    During this period, Adam Smith, the father of modern economics publishedAn Enquiry into the Nature and Causes of Wealth of Nations or popularly calledThe Wealth of Nations. The three main concepts propounded by him weredivision of labour, pursuit of self-interest and freedom of trade. He felt that other

    Sikkim Manipal University Page No. 4

    costs besides wages, such as rent and profit, also affected the price of acommodity.

    Smith believed that division of labour could greatly increase production.

    1.2.2 Era of Scientific Management

    The era of scientific management began in the United States of America in theearly 20th century. Fredrick Winslow Taylor is called the father of scientificmanagement. He propounded the following four principles:

    1. Replace the rule of thumb work method with methods based on a scientific

    study of tasks.2. Scientifically select, train, and develop each employee rather than leaving

    them to train themselves.

    3. Provide detailed instruction and supervision to each worker.

    4. Divide work nearly equally between managers and workers; the duty of establishing standards and enforcing them rests with the managementalone.

    Taylor also propounded the time and motion study. This involved breakingup the job into its component parts and measuring each component in terms of the time required to do it. This study was carried forward by his associates, thehusband and wife duo of Lilian and Frank B.Gilbreth, who coined the term motionstudy. The Gilbreths used a camera to record and examine detailed micro-movements, and invented cyclographs and chronocyclegraphs to observe rhythmand movements.

    Another known pioneer of the scientific management era was Henry Gantt.The Gantt chart that he created is a visual display chart used for schedulingwork based on time; he showed the humane face of management and listed outthe conditions that have a favourable psychological effect on workers.

    By the end of the nineteenth century, the internal combustion engine hadbeen invented and the first assembly line manufacture of cars was started byHenry Ford in Detroit, USA.

    1.2.3 Era of Human Relations

    The impact of behaviour of workmen on their performance was increasinglyrecognized and some experiments were carried out at Hawthorne Works inChicago, USA. These tests called the Hawthorne studies or the Hawthorne

    1.3 Definitions of Production Management

    The domain of Production and Operations Management (POM) is not only limitedto the production of goods and services, but it also comprises all the activitiesthat are related to the process of production. The term production is applicableto entities like manufacturing units, machinery, equipment, assembly lines, etc.Fundamentally, it is linked to manufacturing. In the past, focus was onmanufacturing management, which was later modified to productionmanagement. Production theories and practices were being used in a broadrange of operations and conditions, which have very little or no link with industries

    or manufacturing. The outcome of these activities is not just production of goods,but also supply of services like banking, hotel management, health services,education, transportation, recreation and government operations. As a result of the broadening of the scope, the term production management began to bereferred to as operations management, where the theory, equipment andmethods are used for a varied nature of processes, both, in the manufacturingand in the service sectors.

    Here, we take a look at the definition of production. This process is acombination of one or more procedures that are put into execution for the purposeof conversion or transformation of an array of inputs into a predetermined arrayof outputs, in synchronization with the objectives designated to the productionsystem. Usually, a system comprises a process wherein an input is transformedor converted into the desired output with a feedback procedure, so that anyvariation or discrepancies can be spotted and fixed. This process is known astransformation.

    1.4 Production Process

    The production and operations of goods and services involve the conversion of input into output through a transformation process as shown in Figure 1.1.

    Input TransformationProcess

    Output

    Figure 1.1 Conversion of Input into Output

    As the complexities of organizations grew, it was found that merelyconverting input to output was not enough. Feedback from the output stage wasnecessary to adjust the changes required in input or the transformation process.So, production control was done to take care of fluctuation in inputs, if any. Thequality of the produced output was now constantly compared to the quality of the desired output and feedback mechanisms were put in place to monitor performance of the transformation process.

    Transformationprocess

    Input This includes the six Ms, i.e., man, machine, materials, money, method and management.

    It is a value-addition process that modifies or adds value to the input and converts it into a form that is more useful and sold to a customer, which can be done in many ways as represented subsequently.

    1.5 Production: The Heart of an Organization

    Production is the primary business of an organization. All other wings or activitiesof an organization exist subject to the existence of production. Without productionor anything to sell, there is no organization at all. An organization usually hasseveral departments and each department has a specialized function.

    Marketing establishes the demand for goods and sells what is produced. Finance provides the capital for equipment and resources. Human Resource Management provides and manages manpower.

    Purchasing is concerned with procurement of materials needed to runthe organization.

    Materials Management takes care of inventories. Law Department safeguards the organization on legal issues. Public Relations department builds the image of the organization. R&D is responsible for Research and Development.

    But it is the production department which produces goods and services. Itplays a vital role in achieving a firms strategic goal.

    Customer satisfaction: Customer satisfaction is vital to the survival of an organization. The organization researches the expectations of thecustomer or service to be rendered and decides on the product. Anorganization can survive only if its products satisfy the customers on thebasis of the following criteria:

    (i) Quality of the product as per acceptable standards

    (ii) Easy maintenance and reliability of the product

    (iii) Functionality of the product as offered by the seller Profitability: The pricing of the product should be competitive to achieve

    sales. For this, the market price of products should be competitive andcommensurate with the features offered in the product. A good organizationproduces the right quality that meets all product specifications, at optimalcost. The organization should focus on minimizing costs and maximizingrevenue for increasing profitability.

    Timeliness: The product produced or service rendered may be qualitativeand cost-competitive but if it does not reach the consumers when theyrequire it, the organization loses. The consumer does not wait for a goodor service; he acquires it from a competitor. Therefore, production andoperations management plays a vital role in providing the product or service

    on time by effectively maintaining production schedules.To summarize, we can say that an effective POM needs to produce goods

    or render services of the right quality in right quantities at the right time and atminimal costs. It should also ensure that there is no wastage in the systembecause this results in cost escalations and severe delays.

    If the above-mentioned factors are not kept in mind, then it could lead tofailure of the management in achieving its objectives and targets.

    1.8 Importance of Technology in Production

    Technology makes way for fast and efficient operations in manufacturingcompanies, as well as facilitates cost-saving measures. Technology broughtsignificant changes to traditional production systems that have been so beneficialto all industrial players, including suppliers and customers. A pharmaceuticalcompany, for example, employs advanced machineries in concocting,capsulizing, and wrapping medicine. Traditionally, the making of medicine wasmanually done. However, to prevent contamination and mitigate errors fromhuman intervention, pharmaceutical companies have employed robots andcomputerized machines, resulting in the mass production of medicine at faster speeds and lower costs.

    It is now quite difficult to imagine a world without modern inventions.Countries in Europe, North America, and some parts of Asia are particularlyexperienced at applying modern technology in producing products and services.The Finnish pharmaceutical sector for instance is characterized by a high-levelknow-how, attracting foreign capital to the country.

    1.8.1 The HumanMachine Interface

    Humanmachine interface refers to the user interface in a manufacturing systemor process control system tools used for incorporating the human factors in theinterface design are developed.

    Rapid changes in technology in the last few decades have resulted increating machines that are capable of performing tasks that have traditionallybeen done by people. Robots, for example, have relieved workers of menial anddangerous tasks such as welding or lifting heavy objects. In offices, wordprocessors have broadened the scope of secretaries jobs. On the one hand,technological developments have enhanced the role of the worker in productionsystems. On the other hand, increased automation has resulted in a threat to

    job security; for instance, totally automated factories are a reality in countriessuch as Germany and Japan. This presents a dilemma for operations managers:What should be the proper balance between human work and machine work?

    Automation has significantly changed the nature of the workforce. It hasdecreased the need for low skilled, direct factory workers but has increased thedemand for highly trained specialists. There are now a large number of technical,professional, and managerial workers who are performing complex, long-cycleactivities. A workers time is mostly devoted to mental processes, with muchless time being spent on physical work. The degree of human and machine

    work varies from industry to industry. Human involvement is generally more inthe primary sector and less as we go into the secondary and tertiary sectors.

    The level of automation and use of human labour in an industry should beselected so as to provide the lowest unit manufacturing cost at highestproductivity. The relative roles that human beings and machines have played inproduction have changed during the course of history. Prior to the IndustrialRevolution, manufacturing tasks were performed primarily by people. Activitiessuch as weaving cloth, forging and bending metal, etc. were labour intensive.

    As the Industrial Revolution progressed, machines provided more power for manufacturing, but workers retained much of the control of the process. For example, lathes and drill machines required a large amount of operator assistance. Today, numerically controlled machines and robots permit less humaninvolvement in the production process. In service organizations, we also seeevidence of this evolution in ATMs of banks, railway bookings, etc.

    The focus has now shifted from issues of human production to humanmachine interface. In order to make effective decisions regarding the introductionof new technology, managers need to understand the fundamental differencesbetween machines and people.

    Advantages of humans over machines

    They can think creatively and adapt to new and unexpected situationsmuch better than machines.

    They can take subjective decisions and have reasoning abilities. Buthumans tire after some time; their productivity is not uniform over time;due to boredom, frustration, fatigue, etc., they are not capable of performingheavy-duty jobs and their memory is short and limited.

    Advantage of machines over humans

    They are better suited for complex or repetitive tasks requiring precisionand speed.

    They are accurate, fast and precise and can perform heavy duty taskswhich are beyond the human capabilities.

    They can store and process large amounts of data. They are more reliable and consistent than humans. They do not cause Industrial relation problems like strikes, lockouts, etc. State-of-the-art automated plants increase the market value of the firm

    and improve client base in international markets. But their capability islimited to their programmed instructions. They are less flexible thanhumans and cause unemployment/ retrenchment of work force.

    The goal of the operations manager is therefore to provide the bestsynthesis of technology and people so that the objectives of the organizationare met.

    Technological changes have occurred in every industry and can becategorized into two groups - hardware and software.

    Hardware technologies have resulted in greater automation of processes.They perform labour - intensive tasks that were originally performed by humans.Examples of these major types of hardware technologies are numerically

    controlled machine tools, machining centres, industrial robots, automatedmaterials handling systems, and flexible manufacturing systems. These are allcomputer - controlled devices that can be used in the manufacturing of products.

    1.9 Summary

    Let us recapitulate the important concepts discussed in this unit: Frederick W. Taylor introduced the concept of scientific management. Production and operations involve the conversion of input into output

    through a transformation process. In the industrial revolution era, Adam Smith propounded three main

    concepts: division of labour, pursuit of self-interest and freedom of trade. By the end of the nineteenth century, the internal combustion engine had

    been invented and the first assembly line manufacture of cars was startedby Henry Ford in Detroit, USA.

    The Hawthorne studies or the Hawthorne experiments form the basis of several behavioural and motivation theories.

    Quantitative techniques originated during World War II. Operationsresearch teams were formed to deal with strategic and technical problemsfaced by the military. These techniques were later used for non-militaryapplications as well.

    The ISO 9000 series for quality management systems, and the ISO 14000environment management standards have been established and arefollowed across the world.

    Computerization of information, Internet facilities, digital processes, etc.

    have enhanced effective communication across the levels of hierarchy inthe production process. Production is a process or a set of procedures to be executed in order to

    convert or transform a set of inputs into a predetermined set of outputs inaccordance with the objectives assigned to the production system.

    Production is the primary business of an organization. All other wings or activities of an organization exist subject to the existence of production.

    GM has had a long history in India. Its cars were first imported in Indiabetween 1918 and 1928, mostly by the rich. The first generation of GMvehicles imported into India were Chevrolets small four-cylinder Tourers.They were preferred at the time owing to their fuel efficiency and the ease of

    running them. GM first entered the Indian market with the launch of itsChevrolet brand in 1928.

    After the economic reforms initiated in the early 1990s, especially theautomobile sector and the passenger vehicles segment witnessed massivegrowth. The gross turnover of the Indian automobile market grew from US$20,896 million in 2004-05 to US$ 38,238 million in 2008-09.

    GMI launched the Chevrolet Cruze in the Indian market in October 2009. Itwas well received in the Indian market and got positive reviews from industryanalysts. By June 2011, the Chevrolet Cruze had clocked in sales of 860units per month, making it one of the best performing premium sedans in

    the Indian market. Irrespective of the success of GMIs first small car, theChevrolet Spark, the company could not make any crucial impact on theIndian automobile sector.

    GMI expected that the Beat would increase its Indian sales from 70,000units in 2009 to 100,000 units in 2010. Before the Beat was launched in theIndian market, it was launched in Korea, Europe, and East Asia and wasselling 5,000 units a month in the Korean market. GM hoped to release theBeat in 150 countries around the globe to make it a truly global car. Apart

    from domestic production, GM planned to make India an export hub of theBeat and export 20 per cent of the units to the Europe and Asia Pacificmarkets. By this, GM hoped to follow many other global car manufacturersthat had made India their global automobile manufacturing hub. The increasein the sales of the Beat despite the problems faced by the Indian automobilemarket like increasing fuel prices and high interest rates on vehicle loanswas seen as a sign of improvement in its performance in the Indian market.

    Analysts said that GMI had started to understand the preferences of theIndian customers. They said that high fuel efficiency and the low price tagwere the primary reasons for the success of the Beat diesel in India.
