Research Framework and Literature Review on Service Excellence Systems

The service sector has accounted for more than 65% of global GDP since 2010, according to World Bank data, with contact-intensive service industries such as catering, hospitality, and retail contributing over 40% of total service value added in emerging economies. Unlike tangible goods, services are characterized by intangibility, heterogeneity, perishability, and inseparability of production and consumption, which pose persistent challenges for firms seeking to deliver consistent, high-quality service experiences at scale. Over the past four decades, service management scholarship has generated a rich body of research on the antecedents of service excellence, with three streams of research emerging as particularly influential: service standardization, employee empowerment, and organizational culture. Despite the volume of research, however, existing studies largely examine these three constructs in isolation, leaving the interactive mechanisms through which they jointly shape service outcomes underexplored. A 2022 bibliometric analysis of 1,247 service excellence papers published in top-tier journals including *Journal of Service Research* and *Journal of Marketing* found that only 7% of studies simultaneously incorporate all three variables, and a mere 2% investigate their mutual interactions (Li et al., 2022). This gap is particularly pronounced in the Chinese catering context, where Western-centric theoretical frameworks often fail to explain the success of本土 firms that integrate standardized operations, frontline empowerment, and relationship-oriented cultural practices. This chapter addresses this gap by first tracing the intellectual trajectory of service excellence research, identifying core unresolved debates in the field, and then proposing an integrated analytical framework that conceptualizes service standardization, employee empowerment, and organizational culture as a mutually reinforcing triad. We also outline the research design for the subsequent case study of Haidilao, justifying its selection as a quintessential case of service excellence in the Chinese catering context, and detailing the data collection and analysis methods employed to ensure the rigor and credibility of the findings.

Intellectual Trajectory of Service Excellence Research

The academic study of service excellence has evolved through four distinct phases since the 1980s, each marked by shifting theoretical priorities and core debates that reflect the changing demands of service industries.

1.1 Conceptualization of Service Quality and Excellence

The foundational phase of service excellence research began in the early 1980s, when scholars first sought to define and measure service quality as a distinct construct from product quality. Gronroos (1984) introduced the two-dimensional model of service quality, distinguishing between technical quality (the outcome of the service, e.g., the taste of a meal) and functional quality (the process of service delivery, e.g., the attitude of waitstaff). This model was later expanded by Parasuraman et al. (1988), who developed the widely used SERVQUAL scale, which operationalizes service quality along five dimensions: reliability, responsiveness, assurance, empathy, and tangibles. While these early models focused on customer perceptions of service quality, subsequent scholarship distinguished service excellence from mere customer satisfaction, defining it as a firm-level capability to consistently deliver service that meets or exceeds customer expectations across all touchpoints and over time (Ladhari, 2009). Unlike one-off high-quality service interactions, service excellence requires systemic coordination across multiple organizational functions, from frontline operations to back-office support, to eliminate performance variability across time, employees, and locations.

1.2 The Standardization-Flexibility Trade-off in Service Operations

The first major stream of service excellence research focused on service standardization as the primary lever for reducing performance variability. Building on Taylor’s (1911) scientific management principles, early scholars argued that services could be standardized in the same way as manufactured goods to achieve scale economies and consistent quality (Levitt, 1972). Empirical research in the fast-food and hotel industries demonstrated that standardized operating procedures (SOPs) reduce employee training costs, lower error rates, and facilitate rapid geographic expansion (Heskett et al., 1994). For example, McDonald’s famously standardized every step of its burger-making process, from the weight of each patty (45g) to the frying time (90 seconds), to ensure that a Big Mac tastes identical in Beijing as it does in New York. However, by the 1990s, scholars began to identify the limitations of over-standardization in contact-intensive services. Bitner et al. (1990) found that rigid adherence to standardized scripts can make employee interactions feel mechanical and inauthentic, reducing customer perceptions of service warmth. This led to the core debate of the standardisation stream: what is the optimal level of standardization that balances consistency with flexibility? Later research proposed modular standardization as a solution, separating core service elements (which must be standardized to ensure basic quality) from peripheral elements (which can be customized to meet individual customer needs) (Frei, 2006). For example, hotels standardize check-in and check-out processes but allow frontline staff to offer personalized welcome gifts or room upgrades to loyal customers.

1.3 Employee Empowerment as a Solution to Service Rigidity

The second major stream of research emerged in response to the limitations of over-standardization, focusing on frontline employee empowerment as a mechanism to restore flexibility in service delivery. The theoretical foundation of this stream lies in service-dominant logic (SDL), which argues that value is co-created by firms and customers during service encounters, rather than being embedded in tangible goods (Vargo & Lusch, 2004). Because frontline employees are the primary point of contact during service co-creation, they have unique insights into customer needs that cannot be captured by pre-defined SOPs. Early research defined empowerment as the formal delegation of decision-making authority from managers to frontline employees, such as the ability to offer discounts or waive fees without managerial approval (Bowen & Lawler, 1992). However, subsequent scholarship distinguished between formal empowerment (objective delegation of authority) and psychological empowerment (subjective employee perceptions
