Delta Testing and CX/UX: Elevating the Voice of the Customer

Let's get one thing straight: delta testing does not replace UX or CX. Yes, delta testing, also known as user testing automation, provides exploratory user experience feedback from real-world usage by representatives of your target market demographics. But delta testing's unique deliverables are complements to, not competing with, the work of UX and CX teams.

Keep reading to learn how delta testing's unique deliverables enhance UX and CX initiatives.

CX vs UX vs Delta

User experience sits within the broader category of customer experience. These fields deal with all the ways your customers are interacting with your product and brand. UX measurements include success, error, and abandonment rates, and how long it takes a user to complete a task. Customer experience encompasses an even wider range that extends to the brand, measuring the overall experience, including first touch, how likely a user will be to continue using a product, and how likely they are to recommend your product or brand to others.

Both are dedicated to reducing friction for customers so that all interactions, from completing a desired task, to finding information, to interacting with company representatives, are as positive as possible. And both fields have boasted a long legacy of using customer feedback to inform their decision-making.

The majority of today's companies already have initiatives that listen for the voice of the customer at a broad level and fine-tune features at the interactive level. What delta testing brings to CX and UX is combined qualitative insights and quantitative attitudes. This surfaces customer-driven data about features and experiences based specifically on their impact on product success.

How Is Delta Testing Different from CX/UX?

  • CX and UX focus on the customer's experience at a micro level, while delta testing focuses on their experience with the product holistically.
  • CX and UX are aimed at understanding sentiment and user behavior, while data testing also surfaces quantitative data that highlights specific drivers of customer satisfaction
