Queues: they exist in infamy and for good reason—they’re often seen as a necessary evil for businesses and the bane of any customer. The time wasted standing in line, whether physically or virtually, can counteract even the best customer experience (CX) strategies. Queues are more than a minor inconvenience; they have the power to shape how customers perceive your brand and whether they choose to engage with it again in the future.
In fact, the impact queues have on customer experience is so significant that it’s akin to the tail wagging the dog—a rather fitting analogy given that the word ‘queue’ originates from the Latin word ‘cauda,’ meaning tail.
For decades, queuing theory has been used to optimize queues from an operational standpoint. First developed by Agner Krarup Erlang in 1909, the mathematical principles of queuing theory have helped businesses analyze waiting times, manage resources, and improve efficiency. However, while these operational models are valuable, they often fail to address the human side of the waiting experience. They reduce customers to numbers, focusing on flow and efficiency without considering how those standing in line feel about their experience.
Yet, optimizing queues with a customer-centric approach is far from impossible; it’s about integrating a deeper understanding of the customer journey into every stage of the queuing process. This can be achieved through four key steps: Understand, Measure, Adapt, and Manage.
Step 1: Understand – The Customer’s Waiting Experience
Understanding how customers perceive their time spent in a queue is crucial to crafting a better experience. What causes customers to abandon a queue? What aspects do they find most and least enjoyable?
And most importantly, what suggestions do they have to improve their waiting experience? These are just some of the questions to ask when taking a hands-on approach to customer feedback.
Face-to-face engagement is one of the most effective ways to gather this type of information. Engaging with customers directly while they are in line, or shortly after they’ve completed their service, provides real-time insights into their experiences.
A survey handed out at the moment of service, a quick conversation at the checkout counter, or even a digital survey sent after a visit can all help connect with customers on a personal level and gain meaningful feedback.
Recognizing the Individual
One of the key takeaways from this understanding phase is recognizing that customers are more than just another number in line. Each person in the queue has unique needs, expectations, and feelings. Understanding their perspectives allows you to engineer a waiting process specifically tailored to their needs.
For example, consider the difference between a retail queue and a hospital waiting room. In a retail store, customers may expect quick service and are often willing to stand while they wait. In a hospital, however, the priority is often comfort and anxiety reduction, with patients needing comfortable seating, clear communication, and perhaps distractions like magazines or televisions to ease their concerns.
Taking a customer-centric approach in queues not only shows empathy but can transform an otherwise dull and frustrating wait into a positive experience—setting the stage for a more productive interaction between the customer and service agent.
Case in Point: Disney Parks
One example of an organization that understands the customer experience in queues is Disney Parks. They go to great lengths to ensure that their guests have a positive experience while waiting. Attractions often have immersive line areas with themed decor, interactive displays, or characters to entertain visitors. The goal is not just to manage the line but to make the wait part of the attraction, turning it from an inconvenience into an enjoyable prelude to the ride itself.
Step 2: Measure – Using Data to Benchmark and Improve
While understanding the qualitative side of customer experience is vital, it must be complemented by quantitative analysis.
This is where queuing theory and data-driven approaches come into play.
By establishing metrics, measuring performance, and analyzing patterns, businesses can make informed decisions about how to optimize their queuing systems.
Here are some key aspects to measure and monitor within your queuing process:
- Queue Length: A basic but essential metric, queue length indicates the number of people waiting at any given time. Tracking queue length over time provides a baseline to see how well your queuing system is working and whether optimizations are having a positive effect.
- Wait Times: Measuring how long customers wait from the moment they join the queue to the moment they are served is a critical metric. However, it’s important to note that customers often perceive wait times to be longer than they actually are—by as much as 36%. The emotional state of the customer during the wait can also heavily influence their perception of time.
- Abandonment Rates: This refers to the percentage of customers who leave the queue before completing their intended action, such as walking out of a store without making a purchase or hanging up on a call. High abandonment rates are often indicative of an unpleasant queuing experience and should be minimized as much as possible.
- Peak Service Times: Understanding when customer demand is at its highest (e.g., lunchtime, weekends, holidays) enables businesses to plan for these spikes and deploy additional resources to manage the influx, thereby preventing bottlenecks.
- Service Times: It’s not just about how long customers wait but also how long it takes to complete the service once they reach the front of the queue. By analyzing service times for different tasks, you can allocate the appropriate number of staff or service points based on demand.
- Service Agent Efficiency: Assessing how efficiently service agents handle customer inquiries or transactions provides valuable insights. While not intended for micromanagement, understanding what top-performing agents do well can help create best practices and training guidelines for others.
- Service Point Utilization: This metric measures how effectively each service point (e.g., a cashier, call center representative, or help desk agent) is being utilized. Understanding the ideal number of service agents for each shift ensures resources are neither over- nor under-used.
By analyzing these metrics, businesses can create a more data-driven approach to queue management, identifying opportunities for improvement and setting benchmarks for success.
Step 3: Adapt – Transforming the Queue Experience
Adapting your queuing strategy means moving from analysis to action—taking what you’ve learned from understanding and measuring customer behavior and using it to create a queuing experience that is not only efficient but also enjoyable.
This step is about making queues an integral part of the customer journey rather than a necessary evil.
Choosing the Right Queuing Paradigm
There are numerous queuing paradigms to choose from, and each has its own advantages and challenges. Here are a few common examples:
- Single Queue, Multiple Service Points (Snake Lines): This is often seen in banks and airports, where one line serves multiple counters. It’s perceived as fair because everyone waits in a single line and is served in the order they arrived.
- Multiple Queues, Multiple Service Points (Parallel Lines): This is often used in grocery stores or fast-food chains, where each checkout counter has its own queue. While it allows for greater choice, customers may perceive this system as unfair if certain lines move faster than others.
- Virtual Queues: Virtual queuing allows customers to check in and “save their spot” without physically waiting in line. For example, restaurants may use virtual waiting lists that allow guests to walk around or sit in a comfortable waiting area until their table is ready. Digital solutions like SMS notifications or queue management apps further enhance this experience.
When selecting a queuing system, it’s important to align it with your business objectives and customer needs. No matter which paradigm you choose, there are a few universal principles to keep in mind to ensure a positive experience:
- Keep Customers Engaged and Occupied: Distraction is a powerful tool to reduce perceived wait times. Providing entertainment, information, or activities for customers to engage in can make waiting more tolerable. Retailers might display promotional content, play music, or provide interactive digital kiosks.
- Ensure Fairness and Transparency: Customers want to feel that the queue is being managed fairly. Clearly marking waiting areas, providing updates on wait times, or using a “take-a-number” system can help manage expectations and reduce frustration.
- Create a Comfortable Environment: Creating an atmosphere of ease, comfort, and relaxation makes waiting more bearable. Comfortable seating, pleasant lighting, climate control, and friendly staff can all contribute to a positive waiting experience.
Case Study: Starbucks’ Mobile Order & Pay
Starbucks has adapted its queuing strategy by integrating technology to offer a more seamless experience. With the Mobile Order & Pay feature in their app, customers can order and pay for their coffee before they even arrive at the store. When they get there, their drink is ready for pickup without the need to wait in line. This innovation has not only improved convenience for customers but also increased efficiency for staff and reduced overall wait times.
Step 4: Manage – Continuous Improvement and Optimization
The final step in queue optimization is an ongoing one—managing the system continuously.
This step is about ensuring that your queuing system remains responsive to customer needs, adapting to changes in demand, behavior, and expectations.
The Importance of a Feedback Loop
Queue management should not be seen as a one-time project but as an iterative process. Maintaining continuous engagement with customers allows you to identify shifts in expectations or emerging pain points before they become significant issues. This feedback loop ensures that your queuing system remains aligned with customer needs, business goals, and industry best practices.
Regularly review your queuing metrics and adjust your strategy as needed. For example, if you notice that abandonment rates are increasing during certain peak times, explore ways to deploy more staff, offer virtual queuing options, or provide clearer communication about expected wait times.
Adapting to Changing Environments
Consumer expectations are constantly evolving, and technology continues to play a major role in how queues are managed and experienced. With the rise of mobile apps, self-service kiosks, and AI-driven support, businesses have more tools than ever to create efficient and enjoyable waiting experiences. Embracing these tools and remaining adaptable is key to staying competitive.
Conclusion: The Evolution of Queuing in the Customer Experience
Queues, whether we love or hate them, are an inevitable part of the customer journey. But with the right strategies in place, they can be transformed from a frustrating inconvenience into a positive, engaging experience that aligns with your brand values and customer expectations.
By understanding your customers’ needs, measuring the right metrics, adapting your strategies to meet evolving demands, and managing your queuing systems effectively, you can enhance customer satisfaction, reduce friction, and create lasting impressions that keep customers coming back.
In the end, the art and science of queuing is about balance—finding that sweet spot between operational efficiency and exceptional customer experience, turning every minute of wait time into a meaningful part of the customer journey.
