When vertical development squads leave critical cross-product integration gaps, traditional quality frameworks fail real-world users. This article details the creation of Customer Experience Quality Assurance (CXQA)—a horizontal, persona-based testing discipline designed to bridge the space between QA, UX, and system integration to protect the end-to-end customer journey.
What do you do when you step into an exciting opportunity… only to realize the discipline you’re meant to lead doesn’t exist anywhere in the marketplace?
This is the story of the checkpoints, doubts, frustrations, sparks of clarity, and stubborn belief that led to the creation of a new testing discipline: Customer Experience Quality Assurance (CXQA).
It didn’t start with confidence. It started with a problem.
The opportunity sounded ideal:
“Join our organization to lead our CXQA team.”
With a background in QA, the role seemed like a natural next step. But on arrival, it became apparent that this team wasn’t stepping into an established framework. The real mandate—unspoken but urgent—was to solve a growing issue:
Despite having skilled product squads across multiple value streams, once products hit Production, the service desk was overwhelmed with calls. Customer perception was suffering.
The products were solid individually, but collectively they behaved like strangers. Integration points were fragile. The customer journey, which spanned multiple products and systems, wasn’t being tested end-to-end.
Each value stream operated vertically: deep, specialised, focused.
But nobody was looking horizontally.
Let me bring this to life with a real example.
We build powerful products sold both directly to enterprise customers and via channel partners. One value stream was responsible for Project A—a UCaaS application enabling voice, meetings, and chat. The team executed well: features were delivered, tested, and validated within the application itself. From a vertical perspective, everything passed.
But Project A wasn’t an off-the-shelf product. Before any user could log in, a separate provisioning journey had to be completed—creating a customer instance, assigning subscriptions, and triggering billing. This sat in a different system, owned by another team.
Here’s where it broke down: the release introduced changes to how user identities were handled in Project A, but the provisioning system was still sending the old data format. Both systems worked perfectly in isolation—but at the integration point, the mismatch caused provisioning requests to fail silently.
The result? The product was live, tested, and “green”—but customers couldn’t even access it. Account managers hit errors when provisioning, users never received credentials, and the service desk was flooded with calls before the first login ever happened.
That’s what it means when nobody is looking horizontally.
That gap became my responsibility.
After absorbing the landscape, a simple but transformative idea formed:
If value streams operate vertically, CXQA must operate horizontally.
A horizontal function can:
Operationally, CXQA sits outside of the value streams, currently aligned closest to the UAT function. This positioning is intentional: the UAT environment is the first place where all products come together in a production-like, integrated state, making it the natural vantage point for observing end-to-end customer journeys.
The team itself spans multiple value streams, with individual CXQA analysts often covering several products. Embedding them within a single stream would limit their ability to retain the horizontal perspective required to identify cross-product impacts, integration gaps, and journey-level issues.
In practice, CXQA operates as an overlay rather than a handoff point—engaging with value streams to validate real customer flows, surface systemic issues, and provide feedback that no single team could see in isolation.
However, this model is still evolving. While the current UAT alignment provides strong visibility of integrated experiences, there is a growing need to shift CXQA further left. Earlier involvement would allow observations, risks, and improvement opportunities to be raised sooner—reducing the cost of change and embedding customer-centric thinking earlier in the delivery lifecycle
It wasn’t quality assurance (QA). It wasn’t user experience (UX). It wasn’t system integration testing (SIT). It was something in between—and something new.
A working definition emerged:
More concretely:
This hybrid vision resonated quickly. But then came the hard part: explaining it.
A new discipline only gains traction if people understand it.
“Our CXQA team is pivotal in driving customer loyalty and protecting brand reputation. We combine persona‑based end‑to‑end testing with systems testing to safeguard the whole customer journey and technical integrity.”
“CXQA ensures our brand consistently meets—and exceeds—the expectations of our customers by validating every touchpoint in the customer journey.”
“We merge persona-based testing with systems‑level regression to validate not just functionality, but whether the product feels right to the user.”
Each message was true—just tuned to what mattered to each audience.
This misconception still surprises me.
Everyone recruited into the team had a QA background. And because CXQA had the word “QA” in it, many assumed we were simply an extension of the existing QA function.
Clarification became necessary:
Quality Assurance (QA) | Customer Experience Quality Assurance (CXQA) |
|---|---|
Validates user stories | Looks across all systems and customer journeys |
Tests against acceptance criteria | Performs system integration and persona-based testing |
Focuses on identifying defects | Focuses on ensuring confidence and cohesion across the experience |
Works within individual product scope | Operates across multiple products and value streams |
Measures success by defect detection | Measures success by customer experience quality and system reliability |
Primary goal: Bug discovery | Primary goal: Confidence in end-to-end delivery and overall user satisfaction |
We may find bugs. But that’s not our purpose.
Our purpose is to ensure the system as a whole is safe, sensible, and satisfying.
To effectively execute CXQA activities, a well-defined environment, tooling strategy, and data setup are essential to simulate real-world customer experiences while maintaining control and observability.
Testing is conducted within a Production-like environment (UAT), which hosts a fully integrated ecosystem of products. This setup enables end-to-end validation across multiple systems, closely mirroring real customer journeys without the risks associated with live production environments.
The environment is populated with anonymised production data, ensuring realistic testing conditions while maintaining compliance and data privacy. Sensitive information such as names and email addresses is replaced with accessible test mailboxes, allowing the team to validate key communications such as system-generated email notifications as part of the user experience.
Automated regression testing is executed using Playwright, providing consistent validation of core system behaviors across integrated products. This automated layer is complemented by manual CXQA review, where testers assess:
This hybrid approach ensures both technical accuracy and experiential quality.
Effective CXQA requires more than system access. The following are critical enablers:
Then came the phase nobody talks about—but everyone feels when doing something new.
Periods where I asked myself:
These questions were constant. Daily.
Because when you build something new, the foundation is uncertainty.
What grounded me was this:
This didn’t start as a dream.
It started as a problem statement.
A real organizational need that nobody else was solving.
And in the absence of finding a suitable training or recognised discipline, the only option left was:
Create it.
I tried to find training pathways:
All valuable. None complete.
Then the words of Ralph Waldo Emerson hit differently:
“Do not go where the path may lead, go instead where there is no path and leave a trail.”
I realized I was searching for the comfort of existing pathways. The easy option. The quick win.
But CXQA wasn’t going to fit into existing boxes. So instead of forcing a round peg into a square hole, the answer became clear:
If the discipline doesn’t exist, create the discipline.
If the curriculum doesn’t exist, write the curriculum.
And that’s exactly what happened.
The curriculum now consists of eight modules:
1. Define the Core Competencies: This module develops the advanced capability to design and execute holistic, end-to-end quality strategies that combine system integration testing with customer persona validation, ensuring both technical integrity and real-world user experience.
It equips practitioners with the ability to apply hybrid QA methodologies, leveraging both automation and manual techniques to assess complex, interconnected systems.
Additionally, it builds strong cross-functional collaboration and stakeholder alignment skills, enabling effective communication, defect triage, and confidence in overall system delivery
2. Structure the Curriculum into Learning Paths: This module develops the capability to design and structure scalable learning pathways, guiding individuals from foundational knowledge through to advanced CXQA practice. It equips practitioners with the ability to progressively build expertise in end-to-end testing, automation, and stakeholder alignment across complex systems.
3. Include Real‑World Case Studies
4. Pursue Certification & Industry Recognition
5. Design Hands‑On Labs & Simulations: Practical experience is key to gaining recognition. Incorporate hands-on labs where learners can test real systems or simulate complex environments using case studies. Build virtual labs where they can work on real-time testing issues that simulate end-to-end testing scenarios.
Example Lab: Set up a multi-system integration scenario involving a learning management system (LMS), a CRM system, and hardware interactions (like smart devices). Learners will design and run end-to-end tests from user onboarding to interaction with the learning materials.
6. Build a Community Around CXQA
7. Develop Continuous Learning Pathways
8. Measure, Evaluate & Iterate
With clear progression:
It starts with serving my team and my organization.
But it doesn’t end there.
I’m committed to writing about this, speaking about this, sharing it across the industry, and contributing to a new movement in quality assurance that recognises:
Experience is the new frontier of quality.
And CXQA is the discipline that protects it.
There will be bumps along the way—of course there will.
But CXQA now has:
We’re no longer following a path.
We’re building one.
Lets Hang!
