Service quality (SQ), in its contemporary conceptualisation, is a comparison of perceived expectations (E) of a service with perceived performance (P), giving rise to the equation SQ = P − E. [1] This conceptualistion of service quality has its origins in the expectancy-disconfirmation paradigm. [2]
A business with high service quality will meet or exceed customer expectations whilst remaining economically competitive. [3] Evidence from empirical studies suggests that improved service quality increases profitability and long term economic competitiveness. Improvements to service quality may be achieved by improving operational processes; identifying problems quickly and systematically; establishing valid and reliable service performance measures and measuring customer satisfaction and other performance outcomes. [3]
From the viewpoint of business administration, service quality is an achievement in customer service. [4] It reflects at each service encounter. Customers form service expectations from past experiences, word of mouth and marketing communications. [5] In general, customers compare perceived service with expected service, and if the former falls short of the latter the customers are disappointed.
For example, in the case of Taj Hotels Resorts and Palaces, wherein TAJ remaining the old world, luxury brand in the five-star category, the umbrella branding was diluting the image of the TAJ brand because although the different hotels such as Vivanta by Taj- the four star category, Gateway in the three star category and Ginger the two star economy brand, were positioned and categorised differently, customers still expected high quality of Taj.
The measurement of subjective aspects of customer service depends on the conformity of the expected benefit with the perceived result. This in turns depends upon the customer's expectation in terms of service, they might receive and the service provider's ability and talent to present this expected service. Successful companies add benefits to their offering that not only satisfy the customers but also surprise and delight them. Delighting customers is a matter of exceeding their expectations.
Pre-defined objective criteria may be unattainable in practice, in which case, the best possible achievable result becomes the ideal. The objective ideal may still be poor, in subjective terms.
Service quality can be related to service potential (for example, worker's qualifications); service process (for example, the quickness of service) and service result (customer satisfaction).
Individual service quality states the service quality of employees as distinct from the quality that the customers perceived. [6]
Historically, scholars have treated service quality as very difficult to define and measure, due to the inherent intangible nature of services, which are often experienced subjectively. [7]
One of the earliest attempts to grapple with the service quality concept came from the so-called Nordic School. In this approach, service quality was seen as having two basic dimensions: [8]
The technical quality is relatively objective and therefore easy to measure. However, difficulties arise when trying to evaluate functional quality. [8]
A customer's expectation of a particular service is determined by factors such as recommendations, personal needs and past experiences. The expected service and the perceived service sometimes may not be equal, thus leaving a gap. The service quality model or the ‘GAP model’ developed in 1985, highlights the main requirements for delivering high service quality. It identifies five ‘gaps’ that cause unsuccessful delivery. Customers generally have a tendency to compare the service they 'experience' with the service they 'expect'. If the experience does not match the expectation, there arises a gap. [9] Given the emphasis on expectations, this approach to measuring service quality is known as the expectancy-disconfirmation paradigm and is the dominant model in the consumer behaviour and marketing literature. [10]
A model of service quality, based on the expectancy-disconformation paradigm, and developed by A. Parasuraman, Valarie A. Zeithaml and Len Berry, identifies the principal dimensions (or components) of service quality and proposes a scale for measuring service quality, known as SERVQUAL. The model's developers originally identified ten dimensions of service quality that influence customer's perceptions of service quality. [11] However, after extensive testing and retesting, some of the dimensions were found to be autocorrelated and the total number of dimensions was reduced to five, namely - reliability, assurance, tangibles, empathy and responsiveness. These five dimensions are thought to represent the dimensions of service quality across a range of industries and settings. [12] Among students of marketing, the mnemonic, RATER, an acronym formed from the first letter of each of the five dimensions, is often used as an aid to recall.
In spite of the dominance of the expectancy-disconfirmation paradigm, scholars have questioned its validity. In particular scholars have pointed out the expectancy-disconfirmation approach had its roots in consumer research and was fundamentally concerned with measuring customer satisfaction rather than service quality. In other words, questions surround the face validity of the model and whether service quality can be conceptualised as a gap. [13]
Measuring service quality may involve both subjective and objective processes. In both cases, it is often some aspect of customer satisfaction which is being assessed. However, customer satisfaction is an indirect measure of service quality. Research has also indicated that the presence of service quality leads to several outcomes including changes in perceived value, customer satisfaction and loyalty intentions with consumers. [14] [15]
Given the widespread use of internet and e-commerce, researchers have also sought to define and measure e-service quality. Parasuraman, Zeithaml, and Malhotra (2005, p. 5) define e-service quality as the “extent to which a website facilitates efficient and effective shopping, purchasing, and delivery.” Wolfinbarger and Gilly (2003, p. 183) define e-service quality as “the beginning to the end of the transaction including information search, website navigation, order, customer service interactions, delivery, and satisfaction with the ordered product.”. [16] [17]
A recent paper examined research on e-service quality. [18] The author identified four dimensions of e-service quality: website design, fulfillment, customer service, and security and privacy.
Subjective processes can be assessed in characteristics (assessed be the SERVQUAL method); in incidents (assessed in critical incident theory) and in problems (assessed by Frequenz Relevanz Analyse a German term. The most important and most used method with which to measure subjective elements of service quality is the Servqual method.[ citation needed ]
Objective processes may be subdivided into primary processes and secondary processes. During primary processes, silent customers create test episodes of service or the service episodes of normal customers are observed. In secondary processes, quantifiable factors such as numbers of customer complaints or numbers of returned goods are analysed in order to make inferences about service quality.
In general, an improvement in service design and delivery helps achieve higher levels of service quality. For example, in service design, changes can be brought about in the design of service products and facilities. On the other hand, in service delivery, changes can be brought about in the service delivery processes, the environment in which the service delivery takes place and improvements in the interaction processes between customers and service providers.
Various techniques can be used to make changes such as: Quality function deployment (QFD); failsafing; moving the line of visibility and the line of accessibility; and blueprinting.
In order to ensure and increase the 'conformance quality' of services, that is, service delivery happening as designed, various methods are available. Some of these include guaranteeing; mystery shopping; recovering; setting standards and measuring; statistical process control and Customer involvement management. [19]
The relationship between service quality and customer satisfaction has received considerable attention in academic literature. The results of most research studies have indicated that the service quality and customer satisfaction are indeed independent but are closely related that and a rise in one is likely to result in an increase in another construct. [20] [21]
A service is an act or use for which a consumer, company, or government is willing to pay. Examples include work done by barbers, doctors, lawyers, mechanics, banks, insurance companies, and so on. Public services are those that society as a whole pays for. Using resources, skill, ingenuity, and experience, service provider's benefit service consumers. Services may be defined as intangible acts or performances whereby the service provider provides value to the customer.
Services marketing is a specialized branch of marketing which emerged as a separate field of study in the early 1980s, following the recognition that the unique characteristics of services required different strategies compared with the marketing of physical goods.
The loyalty business model is a business model used in strategic management in which a company's resources are employed so as to increase the loyalty of customers and other stakeholders in the expectation that corporate objectives will be met or surpassed. A typical example of this type of model is where quality of product or service leads to customer satisfaction, which leads to customer loyalty, which leads to profitability.
SERVQUAL is a multi-dimensional research instrument designed to capture consumer expectations and perceptions of a service along five dimensions which are said to represent service quality. SERVQUAL is built on the expectancy–disconfirmation paradigm, which, in simple terms, means that service quality is understood as the extent to which consumers' pre-consumption expectations of quality are confirmed or disconfirmed by their actual perceptions of the service experience. The SERVQUAL questionnaire was first published in 1985 by a team of academic researchers in the United States, A. Parasuraman, Valarie Zeithaml and Leonard L. Berry, to measure quality in the service sector.
Customer satisfaction is a term frequently used in marketing to evaluate customer experience. It is a measure of how products and services supplied by a company meet or surpass customer expectation. Customer satisfaction is defined as "the number of customers, or percentage of total customers, whose reported experience with a firm, its products, or its services (ratings) exceeds specified satisfaction goals." Enhancing customer satisfaction and fostering customer loyalty are pivotal for businesses, given the significant importance of improving the balance between customer attitudes before and after the consumption process.
The following outline is provided as an overview of and topical guide to marketing:
In business, engineering, and manufacturing, quality – or high quality – has a pragmatic interpretation as the non-inferiority or superiority of something ; it is also defined as being suitable for the intended purpose while satisfying customer expectations. Quality is a perceptual, conditional, and somewhat subjective attribute and may be understood differently by different people. Consumers may focus on the specification quality of a product/service, or how it compares to competitors in the marketplace. Producers might measure the conformance quality, or degree to which the product/service was produced correctly. Support personnel may measure quality in the degree that a product is reliable, maintainable, or sustainable. In such ways, the subjectivity of quality is rendered objective via operational definitions and measured with metrics such as proxy measures.
In marketing, a company’s value proposition is the full mix of benefits or economic value which it promises to deliver to the current and future customers who will buy their products and/or services. It is part of a company's overall marketing strategy which differentiates its brand and fully positions it in the market. A value proposition can apply to an entire organization, parts thereof, customer accounts, or products and services.
Inseparability is a term used in marketing to describe a key quality of services as distinct from goods, namely the characteristic that a service has which renders it impossible to divorce the supply or production of the service from its consumption. Other key characteristics of services include perishability, intangibility and variability.
Customer retention refers to the ability of a company or product to retain its customers over some specified period. High customer retention means customers of the product or business tend to return to, continue to buy or in some other way not defect to another product or business, or to non-use entirely. Selling organizations generally attempt to reduce customer defections. Customer retention starts with the first contact an organization has with a customer and continues throughout the entire lifetime of a relationship and successful retention efforts take this entire lifecycle into account. A company's ability to attract and retain new customers is related not only to its product or services, but also to the way it services its existing customers, the value the customers actually perceive as a result of utilizing the solutions, and the reputation it creates within and across the marketplace.
The service recovery paradox (SRP) is a situation in which a customer thinks more highly of a company after the company has corrected a problem with their service, compared to how they would regard the company if non-faulty service had been provided. The main reason behind this thinking is that successful recovery of a faulty service increases the assurance and confidence from the customer.
Intangibility refers to the lack of palpable or tactile property making it difficult to assess service quality. According to Zeithaml et al., “Because services are performances, rather than objects, they cannot be seen, felt, tasted, or touched in the same manner in which goods can be sensed.” As a result, intangibility has historically been seen as the most important distinction between services and products in the literature on services marketing. Other key characteristics of services include perishability, inseparability and variability.
Service recovery is an organization's resolution of problems from dissatisfied customers, converting those customers into loyal customers. It is the action a service provider takes in response to service failure. By including customer satisfaction in the definition, service recovery is a thought-out, planned process of returning aggrieved/dissatisfied customers to a state of satisfaction with an organization/service. Service recovery differs from complaint management in its focus on immediate reaction to service failures. Complaint management is based on customer complaints, which, in turn, may be triggered by service failures. But since most dissatisfied customers are reluctant to complain, service recovery attempts to solve problems at the service encounter before customers complain or before they leave the service encounter dissatisfied. Both complaint management and service recovery are customer retention strategies. Researchers recently proved that strategies such as value co-creation and follow-up can improve the effectiveness of service recovery efforts.

Operations management for services has the functional responsibility for producing the services of an organization and providing them directly to its customers. It specifically deals with decisions required by operations managers for simultaneous production and consumption of an intangible product. These decisions concern the process, people, information and the system that produces and delivers the service. It differs from operations management in general, since the processes of service organizations differ from those of manufacturing organizations.
Consumer value is used to describe a consumer's strong relative preference for certain subjectively evaluated product or service attributes.
