According to the official definition from the Customer Experience Professionals Association (CXPA) — the most reputable global authority in the field:
“Customer Experience is the sum of all perceptions and emotions formed through every interaction a customer has with a business — whether direct or indirect.”
The key lies in the word sum.
CX does not happen in a single moment. It is shaped across thousands of micro-interactions that businesses often do not realize they are creating:
The moment a customer searches for information.
The moment they read a review.
The moment they visit a website for the first time and it loads slowly.
The moment they call a contact center and have to wait.
The moment they receive a rigid or unhelpful response.
The moment they unbox a product.
The moment their complaint is resolved.
…
CX is everything the customer feels when interacting with a brand.
If they feel comfortable — that is CX.
If they feel frustrated — that is also CX.
And because CX exists in the customer’s mind, it is not something the business “creates,” but something the customer experiences.
2. Forrester’s perspective: CX is the science of emotion — not merely a service function.
If CXPA provides the foundational definition, Forrester expands it through a behavioral lens:
“Customer experience is the ability to help customers accomplish their goals effectively, effortlessly, and with positive emotions.”
Forrester highlights three core drivers of CX:
Effectiveness: Did customers achieve what they wanted?
Ease: How much effort did they have to exert?
Emotion: How did they feel throughout the journey?
Among these, emotion is the decisive factor.
Forrester’s research shows that:
“Emotion is the strongest predictor of customer loyalty — stronger than price and product quality.”
This explains why two brands offering similar products and competing in the same market can produce vastly different levels of customer love: one of them manages to resonate emotionally.
