Customer churn analysis: Churn determinants and mediation effects of partial defection in the Korean mobile telecommunications service industry

Retaining customers is one of the most critical challenges in the maturing mobile telecommunications service industry. Using customer transaction and billing data, this study investigates determinants of customer churn in the Korean mobile telecommunications service market. Results indicate that call quality-related factors influence customer churn; however, customers participating in membership card programs are also more likely to churn, which raises questions about program effectiveness. Furthermore, heavy users also tend to churn. In order to analyze partial and total defection, this study defines changes in a customer's status from active use (using the service on a regular basis) to non-use (deciding not to use it temporarily without having churned yet) or suspended (being suspended by the service provider) as partial defection and from active use to churn as total defection. Thus, mediating effects of a customer's partial defection on the relationship between the churn determinants and total defection are analyzed and their implications are discussed. Results indicate that some churn determinants influence customer churn, either directly or indirectly through a customer's status change, or both; therefore, a customer's status change explains the relationship between churn determinants and the probability of churn.     

New Product Strategy, Structure, Process, and Performance in the Telecommunications Industry

A continuous flow of new products is the lifeblood for firms that hope to remain competitive in high-technology industries such as telecommunications. Faced with rapidly shrinking product life cycles, these firms must aggressively pursue the quest for more effective new product development (NPD). Ongoing success in such industries is dependent on choosing the right mix of new product strategy, organizational structure, and NPD processes. Rather than considering the interrelationships among these success factors, however, most previous studies of NPD have examined these issues individually. This shortcoming is compounded by the fact that past studies of NPD have typically cut across industry lines. Gloria Barczak addresses these problems by proposing that a firm's choice of new product strategy, structure, and process are interrelated, as are the effects of those choices on NPD performance. Because these choices and their effects also may be dependent on the unique characteristics of the industry in which a firm competes, her study focuses exclusively on firms in a specific, high-technology industry, telecommunications. The study finds that no single NPD strategy, in and of itself, stands out as being better than any other for the telecommunications industry. Instead, it appears that a company's focus should be on ensuring the best possible fit between its chosen NPD strategy and its corporate goals and capabilities. In keeping with the current focus on cross-functional teams, the study results indicate that project teams and R&D teams are the most effective means for organizing NPD efforts in the telecommunications industry. Perhaps not surprisingly, R&D teams are more important for first-to-market firms than they are for fast followers and late entrants. An R&D team provides the technical skills necessary for playing the role of pioneer. Regardless of the firm's NPD strategy and structure, the presence of a product champion is an important element in the success of new product efforts. In an era of rapid, technological advances, idea generation and screening efforts are essential to the success of telecommunications firms. To ensure that they do not fall into the trap of introducing technology for technology's sake, pioneering and fast-follower firms in particular must recognize the importance of staying in touch with their markets. Such market-oriented activities as customer prototype testing and concept definition and testing can help these firms ensure that their technological developments are in line with customer needs and requirements.     

Regulation and competition in the European mobile communications industry: An examination of the implementation of mobile number portability

Over the past two decades, the mobile communications industry has seen a considerable drop in the consumer switching charges made by service providers in order to promote effective competition and ensure a level playing field for new market entrants. Mobile Number Portability (MNP) is an important regulatory measure taken to reduce switching costs, and it is believed to play an important role in fostering competition in the mobile market. MNP implementation has varied significantly across European Union countries, particularly with respect to porting time and customer fees, both of which are important factors when deciding whether to switch to another provider. The research examines the effects of MNP implementation on competition in the European mobile communications industry. The study findings indicate that subscriber churn rates are negatively affected by both the level of charges levied on subscribers wishing to maintain their current number (porting) when switching mobile providers and the length of time required to switch. The implications of the effectiveness of MNP regulation for competition in the mobile communications industry are discussed.     

Satisfaction of individual mobile phone users in Spain

Consumer satisfaction is a key determinant of consumer retention, consumer welfare, and is also a strategic variable for competition and international comparisons. Spain's mobile customer satisfaction is the lowest in the European Union. The focus of this paper is to identify the determinants of residential mobile phone users' satisfaction among private consumers of mobile telecommunications in Spain. Two innovative aspects of this paper are the focus on a nationwide representative sample of residential consumers in Spain, and the usage of rich individual data to convey high quality statistical information. The correlation of each of the aspects to the overall satisfaction are measured. Also, relationships between different aspects of satisfaction and its determinants are formulated. The paper specifies econometric models and estimates them using a survey of 4249 mobile phone users. The results indicate that customers are less satisfied with larger carriers, and are more satisfied with smaller and newer operators. Policy recommendations are suggested to improve customer satisfaction, contribute to customer retention and improve the position of the country in the international rankings.     

Network effects and preference heterogeneity in the case of mobile telecommunications markets

This paper demonstrates how revealed- and stated-preference analyses can be used for modeling network effects in the field of mobile telecommunications. The aim of this study was to verify if network effects may still play a role in the Polish mobile telecommunications market, measure their strength, identify their sources and variability across consumers by accounting for consumers' observable and unobservable preference heterogeneity, evaluate their monetary value to consumers, and finally, to verify if the marginal utility associated with network effects is constant. The analysis of consumers' revealed choices (currently used mobile telephone operator) allowed the identification of major differences between customer bases of incumbent and new entrant operators, and insight into the business strategies adopted in the presence of asymmetric regulation of mobile termination rates. The second part of the study—the analysis of the consumers' stated choices (made in carefully prepared and designed hypothetical choice situations, known as the choice experiments) made it possible to directly model consumers' utility functions and, in this way, investigate the nature of network effects in mobile telecommunications markets. From the results, the presence of strong network effects, which are related to the ratio of consumers' social network group using the same operator, and to the magnitude of on-net price discounts, is confirmed. These network effects can be disaggregated to pecuniary and non-pecuniary effects. Through the utilization of the random parameters multinomial logit model, consumers' observable and unobservable preference heterogeneity can be accounted for, which proved a scientifically revealing and potentially policy-relevant approach. The results might be of a particular interest to other researchers aiming at modeling consumers' preferences as well as to mobile telephone operators and regulatory authorities—it is shown that capacity for vigorous price competition between mobile operators is limited by non-price factors, which affect subscriber's choices, especially in the presence of asymmetric mobile termination rates.     

The public incumbent's defeat in mobile competition: Implications for the sequencing of telecommunications reform

Within a mere 5 years of market competition, the mobile communications sector in Taiwan has exceeded a 100% penetration rate, currently ranking near the top of the world. In an even more stunning development, the public incumbent, Chunghwa Telecom, has handed the leadership status to a market entrant, Taiwan Cellular Corp., despite phenomenal mobile communications growth. This paper explores the factors that hamstrung Chunghwa Telecom in competition against its rival entrants. Our econometric analysis substantiates the fact that handset subsidies are the most effective instrument for mobile firms to gain market share. Chunghwa Telecom, due to its public ownership status, was nevertheless prohibited at first from adopting such a marketing strategy.The empirical results provided in this paper indeed pinpoint the importance of the sequencing of reform mandates in developing telecommunications: a prolonged privatization could help to promote competition in the industry. Public ownership makes Chunghwa Telecom vulnerable to political intervention and operational inefficiency, which is a barricade to performance and competitiveness for the not-yet-privatized company in a liberalized market. Taiwan's case presents an interesting deviation from conventional development theories, while it deserves scrutiny as it paves a shortcut to successful implementation of telecommunication reform in a timely fashion.     

Competition and regulation in China's 3G/4G mobile communications industry—Institutions,governance, and telecom SOEs

When it comes to the analysis of the intrinsic mechanism of market behaviors and hence competition development and regulatory imperatives in the Chinese telecommunications industry, currently there is no consistent pattern offered in the literature. In China's emergent 3G/4G era, market behaviors can be affected by various institutional factors, along with various forms of informal forces, which may translate into different implications for competition regulation. Based on extensive archival research and interview, this current study aims to bridge the gap by following an interpretive approach. An input–output model was substantiated for pattern-matching in the Chinese context base on the postulation of a series of propositions and hence Industry-Gray-Box. Accordingly, two categories of market behaviors, that is, market-driven vs. institutions-driven, were arguably delineated as being underpinning the competition development. Policy implications and future reform imperatives were discussed. This study may advance knowledge in terms of: (1) the establishment of a relatively consistent pattern for mapping the landscape of China's communications industry; (2) the substantiation of the inner working mechanism of China's SOE system in the telecommunications sector; and (3) original first attempt in identifying different roles of telecom SOEs and the governing forces that affect them. The paper also offers extensive and cohesive insights on China's formal and informal institutional environment in general and for telecommunications in particular. Measurements developed in this study may serve as basis for future study.     

Specific customer knowledge and operational performance in apparel manufacturing

Customer knowledge is an important organizational asset that can be exploited to yield competitive advantage to a firm. However, empirical research on the application of customer knowledge to improve operational performance has been lacking in operations management. In this study we explore how customer knowledge can be used to improve operational performance under a supply chain environment in the clothing industry. We first conceptualize the relationship between customer knowledge and operational performance and delineate their attributes based on a review of the pertinent literature. We then formulate several hypotheses based on past studies and interviews with experienced industry personnel. We develop a self-reported questionnaire to collect data to test the hypotheses. Finally, we conduct a number of regression analyses to identify the key attributes (constructs) of customer knowledge that have a significant impact on operational performance. This paper contributes to research by demonstrating that there are relationships between specific customer knowledge and different facets of operational performance, and provides practitioners in clothing manufacturing with managerial insights on how to leverage customer knowledge for operational performance improvement.     

Development and implementation of customer solutions: A study of process dynamics and market shaping

A broad, dynamic network perspective on solution processes remains scarce. This article presents the process of developing and implementing customer solutions and its effects on the wider business environment by investigating customers and suppliers in the global mining industry (Australia, Chile, and Sweden), analyzing the deployment of a new customer solution, and assessing the changes to the competitive environment and focal firms' relationships with other customers and suppliers. It shows that the forces that drive customer and supplier interests and motivation to co-develop customer solutions may change over time, thus redefining the aim and scope of solutions and creating failure risks. Customers present problems; suppliers respond, on the basis of not only the feasibility of the customer-specific solution but also of their evaluation of future solutions in a broader market; then suppliers aim to standardize successful solutions across markets. Customers want close supplier relationships and unique solutions but also like standardized and repeatable solutions, so they can share development costs with competitors and expose the supplier to competition to avoid lock-in effects. From a network perspective, a novel solution can have a market-shaping effect and evoke reactions from other actors who want to enhance their market position. However, these changes are not necessarily deliberate, and the dynamics that market introductions of solutions trigger may be difficult to predict.     

How value and trust influence loyalty in wireless telecommunications industry

Despite making significant investments in enhancing the customer service experience, long-term customer loyalty remains an elusive dream for many service providers. Particularly in the telecommunications industry, switching providers even from within continuous contract relationships is easy and companies struggle to retain their customers. Trust and value are considered cornerstones of long-term relationships, so it is perhaps surprising that previous research on how relationship age and usage level actually affect value, trust and loyalty is inconclusive. The current research is set in the telecommunications services field and draws on a large-scale survey undertaken in Finland. The findings support the contention that perceived value relates positively to loyalty, and that trust mediates that relationship. Surprisingly, in the telecommunications industry, increasing relationship age and usage level strengthen neither value and loyalty nor the links between trust and loyalty. The results may be explained by the unique characteristics of the highly competitive mobile telecommunications sector, and confirm the view that loyalty does not pay without strategies that value long-term customers and thereby build trust with new customers.     

Termination notice of mobile network operator customers after a tariff switch: An empirical study of postpaid subscribers in Germany

Proactive subscriber churn management strategies of mobile network operators (MNOs) require that steps are taken to keep customers before they hand over a formal notice of termination to their provider. Therefore, several studies have analyzed how MNO customers who gave a termination announcement differ from individuals who did not communicate this message. However, no work has examined such differences among subscribers who recently switched to another tariff of their MNO. Therefore, this paper explores socio-demographic, service consumption and tariff change differences between contract cancellation “announcers” and “non-announcers” in a sample of 1810 postpaid customers who had changed their rate plan not long ago. Cancellation announcers were more likely to be males who decreased their mobile voice consumption after their tariff switch, had already attempted to churn in the past, had moved from an unmetered to a metered rate type, paid higher monthly bill amounts and received no discounts on their current rate plan that was introduced on the market some time ago. Among subscribers who gave a termination notice, early (late) cancellation announcers were more likely to be older (younger) customers with a growing (shrinking) SMS consumption after their tariff switch, had not attempted (had already tried) to leave their current MNO in the past, and were in a rate plan that was (not) recently introduced. The findings contribute to the literature on mobile customer retention and have implications for practitioners and scholars.     

It ain't over 'til it's over: Evaluating reacquisition opportunities in business-to-business markets

Using a qualitative critical incident research technique, this paper examines how sales firms evaluate defected customers in order to determine their worthiness for reacquisition. Findings from interviews with fifty professional salespeople suggest that, when sales firms assess reacquisition opportunities, these opportunities are evaluated based on the likelihood of reacquisition and the value of the customer (i.e., ease of reacquisition and value of the customer). Salespeople report that the barriers to reacquisition, leveraging remaining customer relationship and investigating their own value-adding capabilities are critical in determining the ease of reacquisition. In addition, salespeople report that account size, profitability, market influence and cross-selling potential are fundamental in determining the value of a customer. Furthermore, the importance of ease and value in reacquisition assessments varies with (1) the reason for the customer defection, (2) the formalization of a firm's reacquisition process, and (3) market opportunities. Managerial implications and future research directions are discussed.     

The development and diffusion of customer relationship management (CRM) intelligence in business-to-business environments

CRM data is among the most important and comprehensive information available to management in many organizations. This is particularly the case in business-to-business marketing, where the firm's extended working relationship with its customers is frequently crucial for the maintenance of a healthy business. However, in many instances management has treated CRM data as highly specific to its client relationships and has therefore neglected to analyze this information across market segments, customer categories, and customer–firm relationship forms in order to draw meaningful conclusions for driving business decisions.     

Pricing calls to mobiles: analysis of the UK Monopolies & Mergers Commission Reports on mobile termination charges

The UK Monopolies and Mergers Commission (MMC) nine-month inquiry into fixed-to-mobile termination charges provides an exhaustive analysis of competitive and cost factors in mobile telephony. Its recommendations are discussed and compared with those of the telecommunications regulator, OFTEL, which referred the mobile operators to the MMC after failure to agree a further reduction in charges in early 1998. The MMC, following the same general statutory duty required of OFTEL, to promote competition under the Telecommunications Act 1984, provided a radically different analysis and disagreed with most of OFTEL's specific proposals suggesting that some were anti-competitive. As telecommunications regulators are increasingly required to implement pro-competitive regulation, the MMC's reports show that the evolving approach of sectoral regulators contains some significant flaws.     

Customer interactivity and new product performance: Moderating effects of product newness and product embeddedness

Understanding customer needs which drive significant product innovation is particularly challenging for new product development (NPD) organizations. Research has addressed how organizations benefit from interacting with customers, but more conceptualization is needed into the dimensions of the customer interaction process. In a business-to-business (B2B) setting, customer interactivity is conceptualized as a multi-dimensional construct consisting of bidirectional communications, participation, and joint problem solving during NPD projects. Drawing upon organizational information processing theory, customer interactivity is hypothesized to be positively related to customer information quality when developing highly innovative products, but not when developing modifications or extensions of existing products. Another condition affecting this relationship studied is the embeddedness of the new product in the customer's business environment. Customer interactivity is hypothesized to be positively related to information quality for highly embedded product, but not for low embedded product. Results from a sample of NPD organizations in several B2B industries support these hypotheses. The study contributes to the marketing literature and practice by identifying important dimensions of the customer interaction process which lead to more proactive organizations, and identifying two moderating conditions of the customer interactivity and NPD performance relationship.     

Telecommunications technology applications and standards : A new role for the user

Telecommunications is at a critical juncture in the development of technology, policy and industry structure. The industry is becoming increasingly global and competitive; technology is developing faster than it can be implemented; and telecommunications is becoming strategically important to user organizations. Regulatory bodies and standards organizations are struggling with these developments. Public policy that encourages both competition in the telecommunications industry as well as the organized participation of users in the development of new technology applications, technical standards and industry regulations is essential for realizing the prospective benefits of the information age.     

Technical innovation and 3.5 mobile phone generation: Lessons from Korea

In 1996, the Korean mobile communication market was the first in the world to commercialize the code division multiple access (CDMA). Since then, the voice-based mobile phone market has continued to grow and has now reached near saturation. Having recognized the potential of the mobile data service as a new source of profit, telecommunication operators are scrambling to evolve 3.5 generation (3.5G) technology in order to lead market competition. Recently, the Korean 3.5G mobile telecom market has faced stiff competition from CDMA-based EVDO Rev.A and global system for mobile telecommunications (GSM)-based high-speed downlink packet access (HSDPA). In addition, the world's first wireless LAN-based wireless broadband internet (WiBro) service was commercialized in June, 2006. This paper reviews the current status of the 3.5G technology and analyzes the service standardization strategies from the viewpoint of technological evolutions. This paper also suggests implications for Korea's specific circumstances where different mobile telecom technologies complement and compete with one another. Korea's experiences may serve as important lessons for other countries or operators who try to introduce the 3G and look beyond mobile telecom technologies.     

Customer solutions in the capital goods industry: Examining the impact of the buying center

Based on in-depth interviews with customers, this study explores the customers' view of relevant solution criteria in the capital goods industry. Our research examines (1) whether the initial four-process conceptualization of customer solutions also holds for this industry, or whether it has to be extended and (2) which criteria of the customer solution matter the most for each member of the buying center. This study reveals that customers purchasing solutions in the capital goods industry expect the provider to be excellent in terms of six customer/supplier relational processes, namely (1) customer requirements definition, (2) customization and integration of goods and/or services, (3) their deployment, (4) post-deployment support, (5) signaling activities, and (6) inter-process management. Moreover, we found that the relevance of these processes differs across the most important members of the buying center (users, buyers, and deciders) due to their specific organizational function.     

Does IT alignment between supply chain partners enhance customer value creation? An empirical investigation

In today's hypercompetitive market, a firm's individual efforts, by themselves, are not sufficient to respond to marketplace changes in a timely and effective manner. Rather, the firm must rely on its intermediaries and bundle their respective resources to create responsiveness and added value to customers. In this investigation, the authors draw on the relationship marketing literature and the resource-based perspective to examine how firms can increase their customer value creation by exploring two specific driving forces, i.e., strategic importance of supply chain partners and interfirm integration, and relationship-enabled responsiveness as the dynamic capabilities derived from the driving forces. Using the developed scales for customer value creation, hypotheses are tested on data collected from 184 firms. Results suggest that strategic importance of supply chain partners motivates interfirm integration, i.e., strategic collaboration and information technology alignment, setting the stage for enhanced relationship-enabled responsiveness, and subsequently, customer value creation for the firm.     

The drivers of customer attractiveness,supplier satisfaction and preferred customer status: A literature review

In this paper, we focus on the preferential treatment of buyers by their suppliers. As there is a lack of detailed information regarding the reasons that suppliers serve some buyers better than others, our research addresses a supplier's evaluation of customers and how this evaluation can be influenced by buyers. To give an overview of the drivers of preferential treatment by suppliers, the provided literature review covers three research fields that are considered crucial to this issue: (i) customer attractiveness, (ii) supplier satisfaction and (iii) preferred customer status. By integrating these research topics, we provide a state-of-the-art analysis and overview of the various drivers of preferential treatment, build a preliminary conceptual model and suggest several directions for future research. The identification of the drivers and the resulting conceptual framework can serve as a stepping stone for additional research in this new field.
