Foundations and Implications of a Proposed Unified Services Theory

Diverse businesses, such as garbage collection, retail banking, and management consulting are often tied together under the heading of “services”, based on little more than a perception that they are intangible and do not manufacture anything. Such definitions inadequately identify managerial and operational implications common among, and unique to, services. We present a “Unified Services Theory” (UST) to clearly delineate service processes from non‐service processes and to identify key commonalities across seemingly disparate service businesses. The UST defines a service production process as one that relies on customer inputs; customers act as suppliers for all service processes. Non‐services (such as make‐to‐stock manufacturing) rely on customer selection of outputs, payment for outputs, and occasional feedback, but production is not dependent upon inputs from individual customers. The UST reveals principles that are common to the wide range of services and provides a unifying foundation for various theories and models of service operations, such as the traditional “characteristics of services” and Customer Contact Theory. The UST has significant operational corollaries pertaining to capacity and demand management, service quality, services strategy, and so forth. The UST provides a common reference point to which services management researchers can anchor future theory‐building and theory‐testing research.     

INTERPERSONAL SENSEMAKING AND THE MEANING OF WORK

In this paper, we present a model of interpersonal sensemaking and describe how this process contributes to the meaning that employees make of their work. The cues employees receive from others in the course of their jobs speak directly to the value ascribed by others to the job, role, and employee. We assert that these cues are crucial inputs in a dynamic process through which employees make meaning of their own jobs, roles, and selves at work. We describe the process through which interpersonal cues and the acts of others inform the meaning of work, and present examples from organizational research to illustrate this process. Interpersonal sensemaking at work as a route to work meaning contributes to theories of job attitudes and meaning of work by elaborating the role of relational cues and interpretive processes in the creation of job, role and self-meaning.     

Pricing and Operational Performance in Discretionary Services

In many services, for example, website or landscape design, the value or quality derived by a customer depends upon the service time, and this valuation differs across customers. Customers procure the service based on the expected value to be delivered, prices charged, and the timeliness of service. We investigate the performance of the optimal pricing scheme as well as two commonly used pricing schemes (fixed fee and time‐based pricing) for such services on important dimensions such as revenue, demand served, and utilization. We propose a novel model that captures the above features and wherein both service rate and demand are endogenous and functions of the pricing scheme. In particular, service time is an outcome of the pricing scheme adopted and the heterogeneous valuations of customers, unlike in the queueing‐based pricing literature. We find that the service system may benefit from a greater variance in consumer valuations, and the performance of pricing schemes is impacted by the shape of the distribution of customers' valuation of service time and the responsiveness desired by customers. Both the fixed fee and time‐based schemes do well relative to the optimal pricing scheme in terms of revenue in many plausible scenarios, but there are substantial differences between the pricing schemes in some important operational metrics. For instance, the fixed fee scheme serves more customers and has higher utilization than the time‐based scheme. We also explore variants of the fixed and time‐based schemes that have better revenue performance and show that the two‐part tariff which is a combination of fixed and time‐based pricing can do as well as the optimal scheme in terms of revenue.     

Capacity rationing in rental systems with two customer classes and batch arrivals

Service differentiation is an emerging method to improve profit and to better serve high-priority customers. Such an approach has recently been introduced by one of Europe's leading rail cargo companies. Under this approach, customers can choose between classic and premium services. Premium service is priced above classic service and premium customers receive a service guarantee which classic customers do not receive. The company has to decide under which conditions it should ration its fleet capacity to classic customers in order to increase service of premium customers. We model such a situation as a batch-arrival queuing loss system. We describe the model, solve it optimally, and derive quantities of interest such as service probabilities. We further analyze it by performing numerical experiments based on the data from the company that motivated our research. We show that the potential of capacity rationing can be substantial in situations like the one we analyzed. We also derive conditions under which rationing is especially beneficial, such as under high unit fleet holding costs or in the presence of batch arrivals compared to single arrivals.     

Modeling the Effects of a Service Guarantee on Perceived Service Quality Using Alternating Conditional Expectations (ACE)*

This paper addresses the dearth of empirical research on the relationship between service guarantee and perceived service quality (PSQ). In particular, we examine the moderating effects of a service guarantee on PSQ. While a recent study provided empirical evidence that service quality is affected by service guarantee and employee variables such as employee motivation/vision and learning through service failure, the nature and form of the relationships between these variables remain unclear. Knowledge of these relationships can assist service managers to allocate resources more judiciously, avoid pitfalls, and establish more realistic expectations. Data was obtained from employees and customers of a multinational hotel chain that has implemented a service guarantee program in 89 of its hotels in America and Canada. As the employee variables could affect performance in a non‐linear fashion, we relaxed the assumption of model linearity by using the Alternating Conditional Expectations (ACE) algorithm to arrive at a better‐fitting, non‐linear regression model for PSQ. Our findings indicate the existence of significant non‐linear relationships between PSQ and its determinant variables. The ACE model also revealed that service guarantee interacts with the employee variables to affect PSQ in a non‐linear fashion. The non‐linear relationships present new insights into the management of service guarantees and PSQ. Explanations and managerial implications of our results are presented and discussed.     

Self‐Service Operations at Retail Stores: The Role of Inter‐Customer Interactions

Inter‐customer interactions are important to the operation of self‐services in retail settings. More specifically, when self‐service terminals are used as part of customers’ checkout processes in retail operations without the explicit involvement of retailers as the direct service providers, inter‐customer interactions become a significant managerial issue. In this article, we examine the impact of inter‐customer interactions at retail self‐service terminals on customers’ service quality perceptions and repeat purchase intentions at retail stores. We conduct a scenario‐based experimental design (N = 674) using a 2 × 2 factorial design in which inter‐customer interactions are divided into “positive” vs. “negative” and occur during the “waiting” or during the actual “transaction” stages of self‐services at a retail store. We use attribution theory to develop the hypotheses. The results demonstrate that, through their interactions, fellow customers can exert influences on a focal customer's quality perceptions and repeat purchasing intentions toward a retail store. Furthermore, these influences were impacted by how customers attribute blame or assign responsibility toward the retail store. Service operations managers should leverage these interactions by designing into self‐service settings the capacities and interfaces that are best suited for customers’ co‐production of their self‐service experiences.     

The effects of employee burnout on customers: An experimental approach

ABSTRACT

This study investigated the different effects of employee burnout dimensions (depersonalisation and emotional exhaustion) on customer service perceptions. We hypothesised that customers who interact with depersonalising employees will feel angry and hostile, which, in turn, should be related to low service perceptions. Emotional exhaustion was hypothesised to attenuate this effect because customers might perceive exhaustion as a reason for the depersonalising behaviour and may be affected less negatively. Each of the 156 study participants read 12 vignettes in which university employees displayed depersonalisation and emotional exhaustion symptoms. Multilevel analysis showed that employee depersonalisation negatively affected customer perceptions towards employee service and organisation service. Customer anger and hostility mediated this effect. Employee emotional exhaustion moderated the indirect effect such that depersonalisation had the strongest effect on customer service perceptions via anger and hostility when the employee did not display emotional exhaustion. Findings highlight the importance of studying the effects of depersonalisation and emotional exhaustion separately, and taking into account customer affective processes.     

It takes three to tango: Leadership and hostility in the service encounter

Leadership effectiveness is contingent on the ability to affect followers' emotions. This paper explores a model suggesting that the quality of the relationships between leaders and their followers (LMX) relates negatively to a display of negative emotions by employees during their interactions with customers, and subsequently relates to employees' performance and customers' emotions. The model was tested on a sample of 95 service employees and on 485 interactions between these employees and their customers. The findings show that LMX was negatively related to the display of hostility by employees towards their customers. Employee hostility was negatively related to employees' ability to provide a solution to customers' problems, which was further related to customers' hostility towards employees. We discuss the implications of these findings for both theory and practice.     

Pareto‐Improving Contracts for Express Package Delivery Services

We address the problem of an express package delivery company in structuring a long‐term customer contract whose terms may include prices that differ by day‐of‐week and by speed‐of‐service. The company traditionally offered speed‐of‐service pricing to its customers, but without day‐of‐week differentiation, resulting in customer demands with considerable day‐of‐week seasonality. The package delivery company hoped that using day‐of‐week and speed‐of‐service price differentiation for contract customers would induce these customers to adjust their demands to become counter‐cyclical to the non‐contract demand. Although this usually cannot be achieved by pricing alone, we devise an approach that utilizes day‐of‐week and speed‐of‐service pricing as an element of a Pareto‐improving contract. The contract provides the lowest‐cost arrangement for the package delivery company while ensuring that the customer is at least as well off as he would have been under the existing pricing structure. The contract pricing smoothes the package delivery company's demand and reduces peak requirements for transport capacity. The latter helps to decrease capital costs, which may allow a further price reduction for the customer. We formulate the pricing problem as a biconvex optimization model, and present a methodology for designing the contract and numerical examples that illustrate the achievable savings.     

Service Systems with Experience‐Based Anecdotal Reasoning Customers

The existing queueing literature typically assumes that customers either perfectly know the expected waiting time or are able to form rational expectations about it. In contrast, in this article, we study canonical service models where customers do not have such full information or capability. We assume that customers lack full capability or ample opportunities to perfectly infer the service rate or estimate the expected waiting time, and thus can only rely on past experiences and anecdotal reasoning to make their joining decisions. We fully characterize the steady‐state equilibrium in this service system. Compared with the fully rational benchmark, we find that customers with anecdotal reasoning are less price‐sensitive. Consequently, with a higher market potential (higher arrival rate), a revenue‐maximizing firm may increase the price if the service rate is exogenous, and it may decrease the price if the service rate is at the firm's discretion. Both results go against the commonly accepted pricing recommendations in the fully rational benchmark. We also show that revenue maximization and welfare maximization lead to fundamentally different pricing strategies with anecdotal reasoning, whereas they are equivalent in the fully rational benchmark.     

Lead Time and Price Quotation Mode Selection: Uniform or Differentiated?

Firms in service and make‐to‐order manufacturing industries often quote lead times and prices to customers. We define uniform quotation mode (UQM) as the strategy where a firm offers a single lead time and price quotation, and differentiated quotation mode (DQM) is where a firm offers a menu of lead times and prices for customers to choose from. Both modes are followed in practice. Firms should determine which is more profitable. We classify customers into two groups: lead time sensitive (LS) and price sensitive (PS). LS customers value lead time reduction more than PS customers. We develop mathematical models of both quotation modes and analyze them to determine the most profitable mode under specified situations as well as the best lead time and price quotations within each mode. We find that DQM is dominated by UQM whenever PS customers have positive utilities from UQM or LS customers have positive utilities from DQM. Otherwise, which quotation mode is better depends on multiple factors, such as customer characteristics (including lead time reduction valuation and product valuation of a customer, and the proportion of LS customers) and production characteristics (including the desired service level and service or production cost).     

Modeling and Managing the Percentage of Satisfied Customers in Hidden and Revealed Waiting Line Systems

We perform an analysis of various queueing systems with an emphasis on estimating a single performance metric. This metric is defined to be the percentage of customers whose actual waiting time was less than their individual waiting time threshold. We label this metric the Percentage of Satisfied Customers (PSC.) This threshold is a reflection of the customers' expectation of a reasonable waiting time in the system given its current state. Cases in which no system state information is available to the customer are referred to as “hidden queues.” For such systems, the waiting time threshold is independent of the length of the waiting line, and it is randomly drawn from a distribution of threshold values for the customer population. The literature generally assumes that such thresholds are exponentially distributed. For these cases, we derive closed form expressions for our performance metric for a variety of possible service time distributions. We also relax this assumption for cases where service times are exponential and derive closed form results for a large class of threshold distributions. We analyze such queues for both single and multi‐server systems. We refer to cases in which customers may observe the length of the line as “revealed” queues.“ We perform a parallel analysis for both single and multi‐server revealed queues. The chief distinction is that for these cases, customers may develop threshold values that are dependent upon the number of customers in the system upon their arrival. The new perspective this paper brings to the modeling of the performance of waiting line systems allows us to rethink and suggest ways to enhance the effectiveness of various managerial options for improving the service quality and customer satisfaction of waiting line systems. We conclude with many useful insights on ways to improve customer satisfaction in waiting line situations that follow directly from our analysis.     

The Dark Side of Stakeholder Reactions to Corporate Social Responsibility: Tensions and Micro‐level Undesirable Outcomes

With a review of literature on corporate social responsibility (CSR) and its micro‐level impacts, this paper proposes an integrative framework to map undesirable relational outcomes of CSR activities on internal (employees) and external (customers) stakeholders. By adopting a paradox‐based perspective, the authors determine that unexpected, adverse stakeholder reactions to CSR are driven primarily by either performing or belonging tensions, related to exchange‐ and identity‐based stakeholder concerns, respectively. Specifically, contextual and personal influences can trigger and explain undesirable relational outcomes of CSR. On this basis, this paper offers a research agenda for developing a more refined understanding of CSR‐related tensions and a more nuanced perspective on the business case for CSR.     

Transaction‐Specific Investments,Relational Norms,and ERP Customer Satisfaction: A Mediation Analysis*

Integrating the perspectives of transaction cost economics, the resource‐based view, and resource dependency theory, this study analyzes the institutional settings of enterprise resource planning (ERP) implementations in China. Specifically, it examines how bilateral transaction‐specific investments (TSIs) and relational governance mechanisms influence customer satisfaction with ERP implementations. The model is empirically tested using data from on‐site interviews with 208 ERP customers in China. The results demonstrate that the effects of vendors’ and customers’ TSIs on customer satisfaction are facilitated by multiple‐stage micromediational chains. The influence of TSIs on customer satisfaction is mediated by relational norms, and the impact of relational norms on customer satisfaction is bridged by perceived service quality and customer trust. Furthermore, the influence of vendors’ TSIs is stronger than the influence of customers’ TSIs. The findings contribute to business research and practice by providing valuable insights into how ERP vendors and customers should strategize TSIs to enhance relationship performance.     

Are Self‐Service Customers Satisfied or Stuck?

This paper investigates the impact of self‐service technology (SST) usage on customer satisfaction and retention. Specifically, we disentangle the distinct effects of satisfaction and switching costs as drivers of retention among self‐service customers. Our empirical analysis examines 26,924 multi‐channel customers of a nationwide retail bank. We track each customer's channel usage, overall satisfaction, and retention over a 1‐year period. We find that, relative to face‐to‐face service, customers who use self‐service channels for a greater proportion of their transactions are either no more satisfied, or less satisfied with the service they receive, depending on the channel. However, we also find that these same customers are predictably less likely to defect to a competitor if they are heavily reliant on self‐service channels characterized by high switching costs. Through a mediation model, we demonstrate that, when self‐service usage promotes retention, it does so in a way that is consistent with switching costs. As a robustness check, we examine the behavior of channel enthusiasts, who concentrate transactions among specific channels. Relative to more diversified customers, we find that self‐service enthusiasts in low switching cost channels defect with greater frequency, while self‐service enthusiasts in high switching cost channels are retained with greater frequency.     

Work-related social media use: The mediating role of social media communication self-efficacy

Social media use has become an indispensable part of knowledge work. Employees posting work-related content on social media are considered credible sources of information and have significant importance for how stakeholders, such as potential customers and future employees, perceive the organization. Therefore, employees’ ability to communicate about their work on social media has become a competitive advantage both for individual employees and for their organizations, especially in the professional service sector. Hence, understanding the role of employees’ ability to use these social media professionally is crucial for understanding the communicative behaviors of contemporary knowledge workers. In this study, we draw on social cognitive theory and focus on the antecedents and consequences of self-efficacy in individuals’ work-related communication on social media. The results show that perceived organizational commitment, clarity of communicative role, social media training, and prior experience with social media serve as antecedents of communication self-efficacy and subsequent work-related communication on social media. Thus, organizations and particularly management, have several aspects directly within the scope of their control that may aid employees in engaging in the professional use of social media. The paper contributes to the literature on employees’ communication behavior and provides important and actionable insights for management and the development of human resources.     

通过顾客关系服务化来强化顾客价值过程--顾客关系时代的营销新命题

本文建立在这样一个全新的观念基础之上,即营销资源和活动必须与企业所面临的目标顾客相互一致,同时,顾客价值不是由制造商或服务提供者创造的,而是由顾客在其价值创造过程中创造的.企业的资源、流程和能力并不是企业的生产(如产品)、管理(如网站)、财务(如结算)、法律(如顾客申述的处理)及其它活动过程的结果,而应当被视为顾客价值创造过程的投入要素.因此,供应商的作用是通过向顾客提供恰当的资源要素,如产品、服务、信息、服务补救、个性化关怀等来支持顾客价值创造过程,并与顾客资源形成互动,惟此,顾客才会感知到价值被创造出来.要以此方式运营,企业必须将自己看作是服务企业,而且真正地为顾客服务.为强化顾客价值的生成,企业必须将其客户关系中的所有要素"服务化"(Servicizing),无论是与制造或服务相关的,还是管理、财务或者法律等常规活动.这些常规活动通常属于"隐性服务"(HiddenService),它们在价值创造中的潜力没有得到应有重视.相反,这些要素对顾客价值的生成过程常常起到破坏而不是支撑作用."服务化"意味着要将所有与顾客关系相关的要素,不管它们的类型和特性如何,转化为顾客价值创造过程中的投入要素.最后,本文还探讨了在顾客关系管理时代,如何配置企业营销资源及营销规划等问题.     

Hiding Customer Complaints: Studying the Motivations and Forms of Service Employees' Complaint Concealment Behaviours

This study aims to explore both how and why customer service employees conceal the complaints made by customers. Using an exploratory qualitative approach, data were gathered through the in‐depth interviewing of 25 managers, 25 supervisors and 57 front‐line employees of UK general retailers/supermarkets. Data analysis reveals that the concealment of customer complaints by store employees of all hierarchical levels is common. Front‐line, customer‐contact employees were found to conceal complaints in four ways: through (1) misleading customers, (2) complaint resolution without logging, (3) concealing recorded complaints and (4) falsification of recorded complaints. Store‐level supervisory and managerial employees were also found to conceal complaints in four ways: through (1) complaint resolution without logging, (2) concealing recorded complaints, (3) the non‐recording of complaints and (4) the disregarding of ‘minor’ complaints. The motives for complaint concealment differed between managerial/supervisory and front‐line employees but included reasons of (1) personal protection, (2) perceived customer unpleasantness, (3) serial complaint avoidance, (4) alienation, (5) friends or family protection, (6) instrumental gain, (7) avoidance of additional work, (8) perceived unfairness and (9) limited time. These findings suggest that theorists and practitioners need to acknowledge the existence and prevalence of these motives and behaviours and incorporate them into their conceptualizations and practices.     

Competition and Coordination in Two‐Tier Public Service Systems under Government Fiscal Policy

As a result of government budgetary limits and rapid market growth, many public service systems—such as health care—are characterized by extensive customer wait times that have become a serious problem. This problem might be solved by allowing private firms to enter these markets, which would provide customers with a choice between a free (governmental) public service provider (SP) and a fee‐charging (or “toll”) private SP. In such a two‐tier service system, the two SPs are differentiated by service quality and cost efficiency. This study focuses on the competition and coordination issues for two‐tier service systems with customers who are sensitive to both service quality and delay. The free system attempts to maximize its expected total customer utility with limited capacity, whereas the toll system attempts to maximize its profit. Neither goal is aligned with the social welfare goal of the public service. To achieve the social welfare goal, the government plays a crucial role in coordinating the two‐tier service system via the budget, the tradeoff of social members' goals, and tax‐subsidy policies. Using a mixed duopoly game, we establish Nash equilibrium strategies and identify the conditions for the existence of the two‐tier service system. We employ several interesting and counter‐intuitive managerial insights generated by the model to show that the public service can be delivered more efficiently via customer choice and SP competition. In addition, we show that a relatively low tax‐subsidy rate can almost perfectly coordinate the two SPs to achieve most of the maximum possible benefit of the two‐tier service system.     

Profitability of Service‐Level‐Based Price Differentiation with Inventory Rationing

In this paper, we study the profitability of service‐level‐based price differentiation (SLBPD) in an inventory‐rationing context. SLBPD implies that a company offers several combinations of prices and guaranteed service levels, from which customers self‐select; different customers choose different offerings because they incur different shortage costs if an order is not fulfilled immediately. We develop an analytical model for SLBPD and explore if and when such a service differentiation strategy yields higher profits than a single undifferentiated offering. The results of our analyses suggest that SLBPD is profitable only if a company faces pricing restrictions, e.g., because of competitive pressure or regulatory restrictions. We develop necessary and sufficient conditions under which a specific and relevant form of SLBPD (called “service‐level‐based upselling”) is profitable, and provide an algorithm to compute the optimal parameters of such a policy. Based on this algorithm we carry out numerical analyses that allow us to characterize the profit increment of service‐level‐based upselling. We derive managerial insights into the attractiveness of SLBPD and explain how our basic analytical framework can be extended to account for more complex practical features.
