TECHNICAL AND TECHNOLOGICAL DEVELOPMENT THE FOUNDATION OF SOCIAL CHANGES

Mehmed Avdagi

Economy Academy University Faculty of Education of graduate lawyers and graduate economists for executive staff - Novi Sad, Sarajevo, BOSNIA AND HERZEGOVINA, e-mail: ppdivut@bih.net.ba

Summary: technical and technological development, as the foundation for social changes, cannot be relativized in the sense that social changes also occur independently. Most certainly, they can be significant stimulators for technical and technological development due to their innovations, but they can also be the brakes, which we were convinced of through medieval era of humanity. Therefore, technical and technological progress and development necessarily change social relations as well as the relations of entire society, in which case the institutions of society can help or hinder, but cannot stop the progress because it is in the nature of man to constantly explore and bring innovations into his life and the lives of his contemporaries. Key words: Technical and technological changes, social changes, eras, innovations, pre-industrial age, industrial revolutions, post-industrial society. Technology is defined as practical application of knowledge; as a set of all practical resources which man uses in order to satisfy his needs, i.e. as a systemic application of organized knowledge in practical activities, especially the production activities; as any other tool or technique, the production process and the method used for work or creating something, and which serve the people for increasing their capabilities. Technical and technological products lead to changes in social relations, system of people's thinking, their convictions and way of life. Discoveries of light bulb, telephone, radio, film, television, cars and Internet, during several decades, have led to major social changes in the way of life, organization of life, work, production, business and time of the millions of people. Technology is society, and society cannot be understood, nor illustrated without its technological tools [6]. Therefore, when in 1970s, primarily in the USA, people began to establish new technological paradigm, based on information technology, it was all about a specific part of American society, which has, in interaction with global economy and geopolitics, began to materialize in the new form of production, communication, management and living. The fact that the establishment of that paradigm took place in USA, mostly in California in 1970s, had significant effects on the forms and evolution of new information technologies. For example, regardless of the key role of military financing and market in establishing the early phases of electronic industry during the period from 1940s to 1960s, technology boom that has occurred in the early 1970s, to a certain extent, can be linked with the culture of freedom, individual innovation and entrepreneurship, which have emerged from the culture of American Universities in 1960s. Technology implies the use of scientific and technical achievements in the sense of solving practical problems, and in that way, it has a strong influence on man, organization and way of life, as well as the society as a whole. Which are those big social changes that had a strong influence on both the organization of work and social production, and the latter ones on the society and its changes? If the society does not determine the technology, it can suppress its development, primarily through the mediation of state. Another possibility, again through the intervention of state, is to begin with the accelerated process of technological modernization, which can change the destiny of economy, military power and social welfare in only a few years. Therefore, the ability, or inability, of the society to master the technology that is of a strategic significance to each historic period largely shapes the destiny of society, so we could even say that,

698

although the technology by itself does not determine historical evolution and social changes, the technology is the foundation of society by which it is changing. Social production has passed through big historical periods, eras of production and work, such as: - pre-industrial - industrial - post-industrial Pre-industrial, craft or agrarian era of production and work lasted until the 18th century, and it was characterized by: - hunting and fishing; - agriculture (large share of natural production, and in addition to the use of labor, the physical force of animals had a large share in the production); - crafts and trade; - creation of primitive tools; - construction and architecture (pyramids, Great Wall of China, Greek and Roman architecture); - development of settlements; - division of labor by sex and age. Crafts are based on manual production and direct tools handling, processing largely depended on the craftsman (he is a direct participant and executor of production). Craftsman had to be familiar with all the phases of work (with the appearance of manufacturing, the work process, based on manual work, i.e. craft, is divided into individual partial operations that are performed by particular workers). The productivity is determined and limited by muscle strength, and transport is reduced to manual movement and use of handcarts. Craft work and craft technology of production is slow and expensive, but aesthetic production, in which the product is distinctive, is special and expensive. Significant social effects of craft technology are: - craftsman is respected and enjoys the reputation and status, because he owns the knowledge and skills necessary for that process of work and production; - work conditions in workshops were mostly poor (suffocativeness, humidity, inadequate temperature, great physical efforts, long working days, short vacations); - there existed the producer's satisfaction with the produced object (pride and personal satisfaction with the object that was made and which has materialized their knowledge, skills, work, art and aesthetic); - the work was interesting and it enjoyed a reputation; - economically speaking, work and production process were slow, low-productive and expensive. This era of production, work and society was autarchic; with customs as collective patterns of life and oral culture (press was in traces). Life was subjected to a higher order God is the eternal Creator of everything; you have to work the whole day, from childhood to late old age: non-working days are Sundays and holidays; the children were taught simple rules of life. However, the Age of Discovery has provided the necessary stamp for the development of industry. The Age of Discovery is a period in history that lasted from the half of 15th century to the half of 16th century. During those hundred years, European explorers visited the most of populated areas in the world and discovered that the world is much more spacious and diverse that anyone could imagine. Their reports, which were spreading thanks to the new printing technique, attracted the attention of wide audience. Expansion of geographic and other knowledge was enormous by its width and speed, and thus no other period in history until then can be measured with it. Big geographic discoveries had roots in new technologies and ideas that have appeared during the Renaissance, and they involved the progress in cartography, navigation and shipbuilding. Therefore, the Age of Discovery is considered a boundary between the ending of Middle Ages, and beginning of a new great era of human history called the New Age. The need for greater amounts of floating products at the end of 15th and in the first half of 16th century will lead to the emergence of a new form of production, manufacturing, and to the emergence of the entrepreneurship, because the medieval economy could not adjust the production to the requirements of the world's market. The entrepreneurs organized the production out of the city centers, employing a bigger number of workers, and each of those workers has performed only one action in production process. In that way, the division of labor and specialization were implemented, the productivity and quality of the products were increased and their price was reduced. Manufacture (from Latin manus, hand; facere, to do) is also the name of the new mode of production with implemented labor division and of the workshops in which it was produced in this way. Non-European areas were conquered, European countries were conquering their colonies, which were economically exploited. Colonies served as sources of raw materials and export markets. Colonial forces were maximally exploiting the population of conquered countries. Under the influence of the industrial revolution, there comes to the changes in crafts technology: craftsman is still an important factor of production, but the division of labor and specialization of work are more and more developed, so that the worker performs one or a few work operations, while the craftsman coordinates the process of work and production. Industrial revolution is a term that implies rapid development of productive

699

forces and technology in industry, transition from crafts to machinery is a label for industrial revolution, which occurred when it came to the replacement of biological drive power energy with the energy of the wind, water, coal, liquid fuel. There are two industrial revolutions: (First) Industrial Revolution is the process through which, in the second half of 18th and first half of 19th century in England and then in all other countries of West Europe, an entire series of new technologies was introduced, by which the contemporary economy, based on people's work, was replaced with industry based on steam engine. Industrial revolution has far-reaching consequences on economic, political and cultural situation in Europe and in the world. In the countries that went through industrial revolution, the industry obtained an advantage over agriculture. Industrial revolution has provided for many European countries to rapidly strengthen in comparison with other parts of the world, which has brought to the boom of colonialism in the 19th century, and also to the improved economic and other communication. A new economic and political context is created, and within that context, it comes to the disintegration of feudal systems and ascent of a new social force bourgeoisie. Namely, thanks to the revolutionary changes in the political map of Europe, the bourgeoisie finally takes the leading political role in the countries of Western Europe, and thus the economic force and initiative of the bourgeoisie gained momentum. In the second half of the 19th and at the beginning of the 20th century, it comes to the new scientific and numerous technical discoveries. Then, there was a time of great changes in economy the Second Industrial Revolution. The first oil well was discovered in the USA in 1859. From that moment, the oil will gradually become the most important source of propulsion energy in the world. In the decades that followed the discovery of oil, there were a few revolutionary inventions. In 1885, English engineer Henry Bessemer found the procedure for production of steel disassembled raw iron. That discovery encouraged the development of heavy industry. In 1877, German engineer Nikolaus August Otto designed the engine with internal combustion. In 1896, German Rudolf Diesel invented the engine that runs on oil. Industrial era of production is the era of mass production, which represents a system of industrial production, which is characterized by producing large amounts of products. Is originated as a system of replacing traditional craftsmanship, craft skills and creativity, with mechanized factory operations of mass production, for the production in large amounts. Its strong development has began in 1903, in the Ford car factory in USA by introducing the mobile belts in the production process. In the economic aspect, this type of production has led to the development of labor division, improvement of technological process, development of the production organization, reduction of production costs and increase of profit. From the technical and technological aspect, this is the period of mechanization. In the process of mechanization, the work is intensified and the productivity of work is increased, labor division is more developed, man is freed from the use of manual work because the machine is the one that now performs the operations that were done by man, and it turns the worker into its supplement. For that reason, the number of the employed workers (living labor) is reduced, the work is intensified in the production process and for that reason, it becomes non-creative and alienated, monotonous and boring, and work motivation decreases. The work is simplified and the training for performing it is reduced. Hence, the changes in education occur (in accordance with the knowledge and amount of knowledge necessary for this form of the technology of production). Even though the worker is relieved from fatigue, still, because of the simplified production process and routinization of work, which is uninteresting, non-creative and alienated, there are abstinences, absences from work, and various professional diseases of the producer. In addition to previous characteristics and properties of mechanization, there should also be mentioned the significant social consequences of mechanization, and they are referred to: - relieving the workers from fatigue; - attachment of the machines to one territory, which will provide the faster development for that territory, and it will last until the emergence of electric power and automatization, when the decentralization of production forces starts, which will, with the introduction of nuclear technology, contribute to further development of that process; in that way, the process of abolishing the privileges of particular regions of the industrial development begins; - progress of economy; - dissatisfaction of workers due to poor working conditions (working day lasted for 15, 14, 12, and later for 10 hours, and women and children worked for 14 hours in difficult conditions, even at night); - emergence of trade unions [1] and other workers' associations for the protection of economic, political and social interests of workers. In the period of introducing nuclear facilities, electronic computers and synthetic materials in the practice, there comes to the several waves of scientific and technological development. This period of high developmental investments and strong automatization can be observed through three phases. In the first, there comes to the production and use of new materials, exploitation of the new energy sources, strong expansion of science and technology, as well as the development of modern organization of work, while in the second phase, it comes to a

700

significant increase of work productivity, there is more efficient finding and use of information, as well as the increase of technological knowledge. In the end, the third phase is characterized by an extraordinary development of information technologies. Despite the attempts to observe these phases separately, it is much better to note that it is about one process, with dynamic changes in a relatively short period which is called scientific-technological revolution. Therefore, the transition from the phase of mechanization to phase of automatization is called scientific-technological revolution, which implies the mechanization and automatization of production process (with cybernetics and informatics), the use of new energy sources, changes in the object of work and changes in the content of work (increase of education and eligibility of labor), shortening of working hours, increased leisure time, international integrations, growth of spiritual production (knowledge, science, education, which become significant elements of productive forces), increased development of fundamental services and their quality, professional mobility (change of profession, but also the adoption of new knowledge and skills in the same professions). Characteristics of automatization are automatization of the process of production, assembly and packaging (automatized machines receive the instructions from the environment and decide without the mediation of a man), integration of production processes, continuity of production process, rationalization of production. Automatization can be: - partial such an organization of production and work, in which the producer, man, participates in some production phase (for e.g. switching on or off the mechanical facilities), - complete (total) from which a man is completely excluded i.e. he is excluded from the production process and management. Automatization process brings along the problems and disadvantages that refer to the fact that in its case there is an excess of labor and unemployment, that the producers find it difficult to adapt to the rapid changes, that the old habits are rapidly changing and that there appear new ones, as well as new knowledge and skills, that numerous ecological problems appear. However, besides those disadvantages and problems, automatization also brings along the advantages that refer to the reduction of the participation of direct, living work, reduction of energy consumption, raw materials consumption and the intervention of man in production process, improvement of working conditions, increase of productivity of production, faster mastering of the space, control of biological processes (growth, diseases, maintenance of food). Social consequences of automatized technology of production refer to the fact that work is responsible, that it requires more knowledge, education and experience in relation to the work on assembly line. Post-industrial society is a society of intellectual labor, production of knowledge and information: information are non-material (inexhaustible and durable, because they can be used unlimitedly), mass (mass use) and useful (use-value is increased, if they are used more than once). In post-industrial society, it is evident that education and science are increasingly developed at the global level and they become the initiators of the development of society and social organization of work; organized knowledge is the main driving factor of scientific and technical development; education is very rapidly developed, because scientific and technical development and innovations will represent the essential factors of progress. Scientific, cultural and technological achievements become massively available. Dominance of service industry over production leads to the reduction of the number of employed people in agriculture and industry and feminization of the labor, i.e. mass employment of females. Inconstancy of employment and frequent changing of the production jobs, increase of unemployment rate, increase of social differences between the rich and poor are important characteristics of this society as well as strong urbanization, frequent migrations, changes of residence, increase of time spent for going to work, as well as the increase of social contacts, but it is difficult to establish lasting friendships (alienation). In addition, of course, all of these processes will also bring to the disintegration of traditional families. Therefore, for the post-industrial age, era of production and work, it important and characteristic that in: - economic sector- comes to the transition from processing industry and economy of mass industrial production to the production of services; - technology central significance goes to new industries, based on science and production of knowledge; nit comes to the change in the approach to the use of information; - sociological aspect information society is formed and new technical elites and new forms of stratification are developed, as well as new forms of organization of the social and individual life. Post-industrial era of production and work introduces new technologies, which are highly intensified and which develop a high productivity. They are scientifically, technically and informationally highly determined, require little raw materials and less pollute the environment (with the exception of nuclear technology and biotechnology); influence the development of other technologies and industries, because they are base technologies. In addition, they increase the level of changing the professions, supersede the live work from the sphere of production and increase the unemployment, change the way of life and influence the social changes lead to the changes in organization of work processes.

701

In its essence, post-industrial society is the society of knowledge in the double sense because theoretical knowledge: - more strongly links the science and technology, and in which the research is the source of innovation, and - becomes a significant field of financial appropriation of GSP. Post-industrial society is the society of the new values, new way of life, new forms of communications and new technologies. Providing services, creating intellectual technologies (electronic computers, informatics, cybernetics), the universities and institutes become significant because science and education have a special importance. Production of services (transition from economy of goods to service economy), production of knowledge, information and science (knowledge becomes the foundation of innovations and of shaping the social policy), the existence of telematics, i.e. the connection of computers with telecommunications, social control of technology, dominance of intellectual technologies in the processes of decision-making, socio-cultural technologies in the processes of decision-making, socio-cultural changes that imply changes in the way of life, as well as the changes that emphasize the significance of the ideas, knowledge, science and new values those are the essential technical, technological and social characteristics of post-industrial society. CONCLUSION For understanding the relationship between the technology and society, it needs to be realized that the role of a state, which slows down, releases or leads the technological innovation, is the key factor in the overall process, because it expresses and organizes social and cultural forces that prevail at certain time and in certain space. For the good part, the technology expresses the ability of society to reach the level of technological knowledge by the mediation of social institutions, including the state. Historical process, through which such a development of production forces goes on, is characterized by the properties of technology and its involment in social relations, processes and changes. The same can be said for the current technological revolution. It did not appear by accident and spread itself in the historical period of global restructuring of capitalism, to which it served as key tool. Hence, the new society, which originates from such process of change, is capitalist and information at the same time, although in various countries it brings significant historical variations, depending on their history, culture, institutions and their specific attitude towards the global capitalism and information technology.

QUALITY MANAGEMENT SERVICES

Mira Avramovi High Business School of Leskovac, SRBIJA, e-mail: mimik@infosky.net

Summary: Today, in terms of increasing competition and increasing demands of consumers, quality is the main factor in the survival of companies in the market. Increasing profitability and competitiveness and the development of the overall economy becomes the determining factor of a nation. Quality, effectiveness and competitive advantage become crucial factors in turbulent markets. Access to quality has evolved from terms relating to quality of products and services related to the notion of direction. TQM is the management system that ensures the achievement and maintenance quality, increased flexibility, efficiency and work effectiveness. The TQM system is fully oriented towards the market, and it is a process that begins and ends with consumers. This paper will discuss the dimensions of service quality, use of the TQM approach as a service and the service quality improvement process. For the writing of this paper, the relevant literature in the field of management and other economic disciplines will be used. Key words: service, quality, management services, marketing services, TQM system, the market, consumers. 1. INTRODUCTION Quality as a concept means to produce and provide market services that will fully satisfy the requirements, desires and expectations of consumers. Consumers are becoming more sophisticated, and it requires constant analysis and adjustment of market supply demand. Quality becomes a decisive factor in the effectiveness and competitiveness in a turbulent market. Problems in regards to the quality of service are directly related to the problem of meeting the needs and expectations of consumers. Quality management is an integral part of meeting the needs and expectations of internal and external customers. The process of quality management is linked to the management of internal operations and marketing. It requires a clear understanding of consumer desires and capabilities of the organization for their fulfillment. The system of promotion and quality management has developed rapidly in recent years. They can be categorized in order of occurrence: quality inspection, quality control, quality assurance, total quality control and the TQM approach to quality. Development of service management has led to progress in the standards of quality management. The International Standard (1) is a standard that was written especially for services and is adapted to the characteristics that accompany this activity. The standard explains to "professionals" in the application. It occurs as a result of the development of new concepts of service management, noting among other things, human aspects, social processes, customer perception, image, culture, organization and motivation. Most important is that it points out that consumer assessment of the final measure of quality of service. In addition, he points out that qualitative and quantitative characteristics of the services must be taken into account. 2. DEFININIG QUALITY OF SERVICE The word quality is often mentioned both in business and in everyday life. Many scientists and experts have attempted the answer to the question, What is quality? Depending on the approach and execution, there may be different definitions of the following types of service quality (2):

- transcendental approach and definitions of quality, - production-based definition,

- definition based on the user, - process-based definition, - value-baseddefinitions

The transcendental approach to the definition assumes that there is an unsurpassed service-degree of perfection. This is visible only through the experience of the service. This approach is particularly applicable in the feature and visual art forms. It requires repeated exposure to customer service. From the standpoint of managers, it does not help a lot of statements about the quality of services after the service is used, then it may be too late if the consumer is dissatisfied. Production-based definitions have a precise and measurable definition. The difference in quality is the result of the different ingredients or attributes from which the product is made. So here is a category of objective measurements of adaptable, physical tangible goods, where the taste, needs and preferences of consumers have no influence on the perception of quality. Definitions based on the user starting from the basic conclusion that the quality lies in the eyes of consumers, equated with maximum customer satisfaction. These definitions are subjective and are in demand. The production company gives process-based definitions, where the leading role-played is played by engineers and other specialists involved in the production. It is understood that approval of internally-defined specifications are often conditioned by the desire for greater productivity and lower costs. Value-based definitions of quality are seen in the dimensions of values and costs, ie. Quality is the value for the price. Quality can therefore be defined in different ways and with a distinct standpoint of the product and all processes. Unlike traditional physical, tangible assets, determining the meaning and essence of quality in the service sector is far more complex issue because, "it is not a function of statistical measures of quality, this includes physical disabilities or evaluation managers, it is the way the consumer views the service." (3) Continuing from this point, we can say that quality is, "a set of characteristics of an entity to meet established and expressed needs." Consumers buy products/services because of the benefits provided. The uses may be distinct, but the basic elements serve to satisfy certain desires and needs of consumers. Therefore, the definition should start with the facts. Basic concepts of quality in the service context are therefore to be in its definition and identification of earnings from the consumer, and from the consumers understanding and perception of quality. That proves that the quality of everything that the consumer or target market segments is as the consumer perceives it. Quality is the ability of this product or service to meet or exceed consumer expectations. 3. DIMENSIONS OF SERVICE QUALITY Consideration of the concept of quality in the service sector is very important for any company that is oriented to the market access of business and that the focus is the needs and desires of consumers and ways to respond in a profitable way to them on a long term basis. The positive effects of a strategic services company that issues access to quality is reflected primarily in the following: (4)

- helps the company to achieve a competitive advantage, - contributes to the company's image, - the main prerequisite of building a long-standing loyalty, - increases the value of services and thus enables the formation of higher prices, - increases company profit.

For these reasons, the company must know what the dimensions of quality are that predominantly affect whether the consumer is satisfied or not, and whether or not it has an impact on his decision to buy. Specificity of services and business services sector makes a difference in the perception of quality in the context of service quality and size of manufacturing enterprises, tangible or physical goods. So, for certain durable consumer goods (eg. refrigerator), dimensions of quality defined in terms of manufacturing companies could present through the following: (5)

- performance - how it works - features - product attributes - reliability (whether or not it spoils) - appropriate specifications - validity (providing value over the long term) - the possibility of repair service - sensuous feeling of consumers (aesthetics, smell, taste) - perceived quality (the impact of reputation, brand, etc.).

Dimensions of the quality of service companies are subject to separate analysis. Specificity of services affects the specificity of observation dimensions of quality. Consumers are more difficult to objectively measure the quality of services in relation to the quality of the product, because there are fewer tangible signs (associated

704

mainly with the service environment and related products). In addition, the perception of service quality result from (subjective) comparisons of consumer expectations with actual service performance, which is again difficult to determine and compare in terms of the quality standards. Scores are made on the basis of results (used) services, but include a service evaluation process (delivery). According to the SERVQUAL model of service, quality dimensions are (6):

- reliability (ability to deliver promised services in an appropriate manner), - responsibility (effort, willingness to help and provide prompt service) - security (knowledge and courtesy of employees, and the ability to gain their trust) - empathy (providing personalized service, monitoring the customer as an individual) - tangible elements (presence of natural elements - the materialization of services).

SERVQUAL is a multidimensional scale that compares the perception of consumer expectations in terms of quality of service. Perceptions are measured on a scale of 1 (not at all agree) to 7 (total agreement). The results are compared with the responses of consumers in terms of expectations of "world-class companies," (ie. "great company" or "excellent company" in a given industry). While the specific issues related to the particular enterprise customer experience with the services of the company, and therefore define their perception (ie. the consumers personal vision) of which the results are given to an imaginary or real ideal company, in fact, represent the wishes and expectations of consumers in the service given business. The results are comparable in general and on specific dimensions and reveal where the largest discrepancies in consumer expectations are in the service sector. 4. APPLICATTION OF TQM, APPROACHES IN SERVICE The largest number of applications of the TQM approach was usually limited to the industrial sector. Managers have been under the influence of traditional thought and, until recently, believed total quality should be measured only if it produced a tangible product. However, it is now observed in the components that TQM philosophy is applicable to all business sectors, including service companies. Service companies must also prepare for the fierce competition within the service industry. The TQM approach, especially in recent times, has attracted more attention as the solution or key to continuously improving quality, and thus also achieving long-term competitive advantage. This approach does not always provide the expected results, but it creates a satisfactory improvement in the quality and competitive advantage. Quality improvement leads to a reduction in costs resulting from reduced errors and omissions as well as increased sales, which are the result of higher levels of customer satisfaction. The process of improvement of service quality has the essential aim to increase income from sales, and reduce costs by reducing or eliminating errors and omissions in the provision of services. Adoption of profitable decisions related to the cost of quality improvement is a key management issue. All efforts for the improvement of quality must be financially justified, which means knowing where to invest efforts and when to reduce their investments. The effects of improvement of service quality are: (8) Increased capabilities of service companies to attract consumers because of the positive personal message (word of mouth), as well as the ability of companies to promote their offers. This effect has a great similarity with the repositioning of products and is part of "offensive marketing," which strives to attract new consumers. Increased current customer satisfaction leading to repeat purchases so that small customer retention rates have an enormous impact on company profits. Marketing costs to attract new customers are five to six times higher than the costs of retaining existing customers and to existing customers, who tend to buy more than new customers. The way to keep current customers with a higher level of satisfaction is called "defensive marketing." The TQM model must take into account access to the quality of yield. This approach to quality is based on several assumptions:

- quality of the investment, - efforts to improve quality must be financially justified, - it is possible to overspend on quality, - not all costs that are invested in quality are equally valid.

The process of quality management can be presented in a new way of using the model of service quality improvement and profitability. The model requires that the costs of quality improvement are treated on the same basis as other investment decisions. The absence of treatment costs as a result of lack of investment is a solid basis for assessing the financial impact. The model provides a framework for evaluating the financial impact of the efforts that have been taken into account to improve quality. The second assumption says that the efforts related to quality must be financially justified, or as a synergy, assuming that the quality justifies investment.

705

Some efforts to improve can be inefficient in the sense that there is too much wasted (decreasing returns), or that the money is spent on improving the wrong things (inefficient use of funds). The last two assumptions of the model must be fully consistent with the first two assumptions. Gronroos proposed a program of quality management services that helps implement a service management strategy, which causes a constant increase in service competition, as it should be increased. This program is composed of six subprograms:

- development of service concepts, - consumer expectations management program - service score management program, - internal marketing program, - physical environment management program, and - consumer perception management program.

The construction of a consumer-oriented service concept allows management to create high-quality resources and successful activities. Traditional marketing activities should never be planned and implemented in isolation. One must always be associated with the experience and skills of service providers who are ready and able to provide a service to consumers. The issue of managing customer expectations is an integral part of each program to achieve quality of service. This being the case, the intense management communication is an important element of service management. Technical quality of service is the result of interaction between consumers and sellers and is a part of the overall experience of services. The product of interaction is necessary in developing and maintaining accordance with the service concept, which is in line with the needs and desires of target consumers. The key to superior service quality and achieving competitive advantage is the functional quality of the process, which is observed in the interaction between customer and vendor services. This dimension of quality is dominant and is reflected through courtesy, flexibility, and general service staff to contact preference through their ability and willingness to act as part-time marketers. One of the major features of access control for total quality is the way we attract managers from all parts of the organization to work together, beyond the traditional functional boundaries, in order to improve quality and management. As a result, quality becomes an integral concept of production and marketing orientation. Marketing is always lacking in the method by which it can reconcile the wishes of consumers on the one hand, and possibilities for their satisfaction of the company on the other. Quality management services are a relatively unknown link. Therefore, the proposed series integration link between marketing and operations phases of planning and execution of operations are oriented to the improvement of quality. The effects of such management should be visible through improved productivity by way of improved sales (build loyal customer bases). The service quality management program should provide adequate orientation to managers in the field of providing services to consumers. The internal service provider market, contact staff, managers, marketers and other types of employees should be considered first. In that sense, continuous and strategic internal marketing processes are assessed as a key in the development of quality management. Physical resources, technology and system service organizations must be developed in line with efficient internal standards. The resources and physical environment can often produce a negative impact on the perception of the interaction between seller and buyer services. Therefore, management of the physical environment is an indivisible part of the overall program quality. It is advantageous to inform consumers on how to proceed in the interaction between customer and consumer services. If the consumer does not want, or does not know how to behave in accordance with the expectations of service providers, the quality can be destroyed. This can be reflected through the long waiting periods or a gloomy atmosphere, which greatly deteriorates the quality of services. 5. PROCESS OF IMPROVEMENT OF SERVICE QOALITY Improving service quality is not a simple process, considering that there must be significant implications for the entire culture of the organization. Activities that may lead to the successful improvement of service quality are:

- identifying the primary determinants of service quality, - managing consumer expectations, - manifestations management, - consumer education regarding service, - developing a quality culture, - automatic quality, - monitoring services.

706

Recognizing determinants of service quality is crucial for improving quality. There is a problem because consumers and service providers are not necessarily perceived service quality bas
