Actually yes, Cost-Effective Service Excellence is Doable!
Service excellence and cost effectiveness are seen to be in conflict, yet there are organizations that achieve both. What do these great organizations have in common: Google, Amazon, USAA, Vanguard, Singapore Airlines, JetBlue and Narayana Health? Believe or not, but they all are among the leaders in their respective industries in terms of both productivity and customer satisfaction! That is, they are one of the top quality service providers and at the same time they have the highest labor productivity and lowest unit costs in their industry. We termed this Cost-Effective Service Excellence (or “CESE” for short). How did these organizations achieve this?
Analyzing how 10 CESE organizations did it, Valarie Zeithaml and I identified three core strategies these organizations followed. The 10 organizations and the strategies they pursued are shown in Figure 1.

Dual Culture Strategy
First, a dual culture strategy provides a comprehensive set of high quality services at low cost. The dual culture strategy is akin to ambidextrous organizational approaches in the management literature with a focus on leadership ambidexterity and contextual ambidexterity (but not much structural ambidexterity). One factor common to all these firms is a dual culture strategy, taking an ambidextrous approach to business challenges and embracing – rather than avoiding – what others might see as contradictions.
The organizations in our sample that successfully achieved the dual culture strategy combined an intense focus on costs with equally passionate customer centricity and focus on service excellence. Specifically, they showed an extreme deployment of generic productivity strategies and tools that allowed them to minimize the gap between actual and potential efficiency while delivering service excellence.
For example, Singapore Airlines (SIA) cabin crew undergo some of the most rigorous service training in the industry, instilling a business culture that is exceptionally customer-centric. As a result it is regularly voted one of the best airlines in the world. Yet it is also one of the most obsessively cost conscious and at SIA – apart from issues of safety and security – no cost is too small to reduce.
Company leaders, internal communications and training continuously emphasize that profit is a function both of service excellence and costs. Staff are taught that anything that touches the customer must ooze SIA’s premium positioning, whereas everything behind the scenes is subject to extreme cost control.
At Amazon, for example, customer obsession and frugality are core values. The firm’s CEO, Jeff Bezos, is known for his passion for putting the needs of its customers first, demanding employees chase solutions to any customer complaint that comes his way. At the same time, he role-models and communicates frugality on anything that does not add value to customers. Amazon actively avoids spending money on things that don’t matter to customers. “Frugality breeds resourcefulness, self-sufficiency, and invention,” Amazon’s leadership principles state.
At Narayana Health, Dr. Devi Shetty, the group’s founder and chairman, once explained to me that “the notion that ‘if you want quality, you have to pay for it’ went out the window a long time ago”.. His senior employees receive daily text messages detailing the group’s expenses, maintaining focus on keeping costs low and driving ideas for savings and process improvements.
Narayana Health has an intense focus on cardiac surgery quality and success rates. Yet surgeons also constantly compare ideas on how to cut costs, such as through the routine sterilization and reuse of medical devices that were sold as single-use products. Another cost saving step involved redesigning the processes before and after surgery to allow operating theatres to be used for 20 hours a day.
Chef Davide Oldani, founder and head chef of Ristorante D’O in northern Italy, is passionate about making the Michelin-starred restaurant accessible to a broad audience through low prices and repeatedly communicates this to key stakeholders. To reduce costs Oldani introduced multi-tasking, cutting the need for wait staff by having chefs serving the food. He chose less fragile glasses and plates to cut replacement costs and opted to locate his restaurant in a low rent area 20 km from the city, running at 100% capacity for all lunch and dinner shifts to reduce unit costs.
Furthermore, the dual culture approach in our case organizations required a rationale employees could buy into as it seemed counterintuitive to offer great service externally, but be stingy internally. That is, employees need a credible rallying cry concerning why cost-effectiveness is critical in addition to service excellence. The organizations in our study did this by emphasizing various rationales. These include: a mission to provide the best customer value (Amazon); recognition that they operate in a hyper-competitive industry (SIA); making Michelin-starred food affordable (Ristorante D’O); and supporting a charitable cause (Narayana Health).

Operations Management (OM) Approach
Second, an OM approach reduces process variability and thereby allows the increased use of systems and technology to achieve CESE. Organizations that pursued an OM approach included Amazon, Vanguard, Google and USAA. See Tables 3 and 4 for examples.
The OM approach addresses the root causes of inefficiencies in service processes through OM approaches that reduce customer-induced variability and thereby reduce potential conflicts between productivity and service excellence. Unlike a pure dual culture approach, these OM approaches typically require some degree of change in the customer interface. They include (1) isolating and industrializing the back office, and reducing the front office, (2) modularization of service, and (3) self-service technologies (SSTs).

The Focused Service Factory Strategy
Finally, the focused service factory strategy can enable CESE through a highly specialized operation, typically delivering a single type of service to a highly focused customer segment. That is, the focused service factory features tightly-defined and industrialized service processes targeted at a highly homogeneous customer base. As a result, the focused service factory delivers reliably exactly what its target customers want. It also reduces customer-induced variability to a minimum—customers tend to receive a single, highly standardized, and excellent service offering. See Tables 5 for an example.
Interestingly, the three strategies can be applied in isolation or in certain combinations, where by each strategy can be pursued alone, or the OM and focused service factory strategies can be pursued in combination with the dual culture strategy (see Figure 1).

Conceptual Framework and Key Take-Aways
Service excellence and cost effectiveness are perceived to be in conflict, yet there are organizations that achieve both. Organizations that successfully pursue a dual strategy have been shown to outperform their peers. It is suggested that competitive pressures make it critical to take the management of such contradictions and paradoxes seriously. In particular, sustained performance occurs through attending to and dealing with strategic contradictions. Based on an integration of literature and case examples, we propose that the successful management of service excellence and cost-effectiveness is a contradiction that can be achieved as is outlined in the conceptual framework in Figure 2. This framework provides an integrated view on the strategic options organizations have when aiming to pursue a strategy of CESE.

Furthermore, many leaders pursue strategies to improve customer satisfaction (service quality) and cost-effectiveness/productivity at the same time. At the moment there are no clear guidelines on how they can do this without creating conflicts between these two objectives. The so what of this research is that it helps managers to think about how to go about improving productivity while also increasing or maintaining service excellence. It provides three clear strategies to do so and allows managers to develop their own strategic approach to CESE and then to clearly articulate how they will achieve cost-effective service excellence.
The level of variability in customer service processes and resulting business models seems to be a strategic decision. If a business model keeps variability high, it requires an extraordinary effort to achieve CESE largely through leadership ambidexterity and contextual ambidexterity to successfully execute a dual culture strategy. Alternatively, variability can be reduced either on the process-side through OM approaches, or on the customer-input side through the focused service factory strategy. These alternatives imply very different business models with different value propositions and customer segments.
Even within a given business model, service firms need to be intensely aware of the cost implications of providing options, flexibility, customization, and added products and features offered to their customers. Complexity and uncertainty grow exponentially and reduce the level of potential productivity while making it more and more difficult to deliver service excellence. Therefore, it is an important and strategic decision how much variability a business model should contain, and if OM strategies and tools are pursued, how variability should be reduced while aiming to delight customers.
The focused service factory model offers many interesting business opportunities in both the offline world as well as the online world where services are increasingly delivered through apps on smartphones. Such focused service factories typically combine smart processes and new technologies that provide tailored solutions for well-defined problems and narrowly defined customer segments. For example, in healthcare, Narayana Health decided against building a general hospital that intertwined many service processes and patient segments and therefore would have been incredibly complex and expensive without the same quality output. The principle is simple: a specialist who only delivers a single product to a single segment will be faster and better than the generalist who must cater to a wide range of customer needs.
Finally, rapidly developing technologies that become better, smarter, smaller, and cheaper (e.g., geo-tagging, robotics, drones, virtual reality, speech recognition, the Internet of Things, and artificial intelligence) will transform virtually all service sectors, and bring opportunities for a wide range of service innovations that have the potential to dramatically improve the customer experience, service quality and productivity all at the same time. The framework developed in this research offers a strategic lens through which these new services can be viewed and approached.
Empirical evidence suggests that once companies successfully achieve a dual strategy of CESE, they reap the highest long-term financial return compared to organizations that focus on either customer satisfaction or productivity alone. CESE is clearly highly desirable, but very difficult to achieve. Our paper provides three strategic avenues managers can achieve CESE.
