The Three E’s of Customer Satisfaction. How the CX Index Can Help You Keep Customers Happy

The customer experience index (CX index)

The customer experience index (CX index) is a metric used by businesses to measure customer satisfaction and loyalty. It is a powerful tool that can help companies identify areas of improvement and provide a better overall customer experience.

The 3 E’s – effectiveness, ease, and emotion

The CX index is based on three main factors: effectiveness, ease, and emotion. Each of these factors plays a critical role in determining the overall customer experience.


Effectiveness refers to the customer’s ability to achieve their desired outcome or goal. This could be anything from finding the right product or service to resolving an issue or problem. If a customer can easily achieve their goal, they are more likely to have a positive experience and be satisfied with the company.

Compelling customer experiences are critical to business success. A customer who can easily achieve their goal is more likely to become a loyal customer and recommend the company to others. This is why companies need to understand their customers’ needs and desires and design their products and services accordingly.

One way companies can improve effectiveness is by providing personalized experiences. Personalization can take many forms, such as offering customized recommendations based on a customer’s past purchases or tailoring marketing messages to their interests. By providing personalized experiences, companies can improve customer satisfaction and loyalty.

Another way companies can improve effectiveness is by simplifying their products and services. This could mean reducing the number of options or streamlining the checkout process. By making it easier for customers to achieve their desired outcomes, companies can increase satisfaction and loyalty.


Ease refers to the simplicity and convenience of the customer’s interactions with the company. This could include everything from the ease of finding information on the company’s website to the ease of contacting customer service. If a customer has to jump through hoops to complete a task or get help, they are less likely to have a positive experience.

Ease is also critical to the customer experience. Customers expect interactions with companies to be simple, convenient, and seamless. If a customer has to jump through hoops to complete a task or get help, they are less likely to have a positive experience.

One way companies can improve ease is by investing in technology. For example, chatbots can be used to provide immediate assistance to customers and reduce the need for human customer service representatives. Additionally, self-service options, such as online FAQs and tutorials, can empower customers to find solutions to their problems independently.


Emotion refers to the customer’s emotional response to their interactions with the company. This could include feelings of happiness, frustration, anger, or satisfaction. Emotion is significant in determining customer loyalty and whether they will recommend the company to others.

Emotion is a crucial factor in determining the overall customer experience. Customers’ emotional responses to their interactions with companies can determine whether they become loyal customers or switch to a competitor.

One way companies can improve emotion is by providing exceptional customer service. When customers feel that a company cares about their needs and is willing to go the extra mile to help them, they are more likely to have a positive emotional response. This could include anything from resolving an issue quickly to providing a personalized solution.

One real-life example of a customer satisfaction experience is the case of Zappos, an online shoe and clothing store. Zappos has a reputation for providing exceptional customer service, and its commitment to customer satisfaction is reflected in its policies and practices.

One particular instance of Zappos’ exceptional customer service involved a customer who ordered a pair of shoes for her mother, who was terminally ill and had swollen feet. The customer called Zappos to ask for help in finding a comfortable and easy-to-wear pair of shoes for her mother.

The Zappos customer service representative went above and beyond by offering to send several pairs of shoes overnight, free of charge so that the customer could find the perfect pair for her mother. The representative also expressed her condolences and sent flowers to the customer after her mother passed away.

This level of personalized and compassionate customer service is rare in today’s market, and it exemplifies the kind of experience that can create customer loyalty and advocacy. The Zappos case is a prime example of how prioritizing customer satisfaction and going above and beyond can lead to exceptional customer experiences.
