DXPS is an independent international standard developed by Eric Chuar Technologies for evaluating digital experience and performance across websites, applications and customer journeys. It combines user research, task completion, accessible interaction, responsive design, content clarity, localization, Core Web Vitals, resilience, privacy-aware measurement and continuous improvement in one evidence-based conformance framework.
Direct definition
What is DXPS?
DXPS is an independent international standard developed by Eric Chuar Technologies for evaluating digital experience and performance across websites, applications and customer journeys. It combines user research, task completion, accessible interaction, responsive design, content clarity, localization, Core Web Vitals, resilience, privacy-aware measurement and continuous improvement in one evidence-based conformance framework.
DXPS is intended to make conformance review practical. It does not award status for intent alone: the applicant identifies a bounded system, names accountable owners, operates applicable controls and supplies evidence that can be traced to the current version. The assessment considers design and operation together because a policy that is not followed, or a technical control with no accountable decision path, is not sufficient evidence.

Purpose and intended outcomes
What DXPS is designed to achieve.
A user-experience, accessibility and performance standard for clear, resilient and measurable digital journeys. The standard gives technical and non-technical stakeholders a common way to define expectations, inspect implementation and record residual risk without implying that one control pattern fits every organization.
- Priority user tasks defined and tested with representative people and conditions
- Accessible, keyboard-operable and readable interfaces across supported devices
- Performance budgets connected to loading, interaction and visual stability
- Clear content, error recovery and localization controls
- Ongoing field measurement that respects privacy and triggers accountable improvement
Who should use it
Accountability spans buyers, builders and operators.
Use is appropriate when the organization can identify the subject of assessment and the responsibilities it actually controls. Suppliers may contribute evidence, but outsourcing work does not outsource accountability for an applicant's decisions.
- Organizations operating customer or employee digital journeys
- UX, research, content, design-system and accessibility teams
- Frontend, platform and performance engineers
- Marketing and SEO teams responsible for technical experience quality
- Assessors and procurement teams comparing experience evidence
Scope boundary
Systems and lifecycle stages included and excluded.
Included
Public and authenticated web experiences, responsive applications, content journeys, forms, navigation, performance delivery, localization and the measurement practices used to improve them.
Excluded and not implied
It does not guarantee conversion, search ranking or universal accessibility, replace user-specific accommodation, or represent W3C, Google, ISO, government or statutory certification.
The assessment statement must identify organizational boundary, systems, interfaces, locations, lifecycle stages and material providers. Shared platforms can be included only to the extent that responsibilities and evidence are available. A narrow scope is acceptable when it is described honestly; ambiguous scope is not enlarged by marketing language.
Normative language
How to read the requirements.
Shall
A mandatory requirement for the declared scope. An exclusion needs a justified scope decision, not silent omission.
Should
A recommended practice. A different approach may be accepted when evidence shows an equivalent, context-appropriate outcome.
May
A permitted option that does not become mandatory merely because it appears in guidance.
Evidence
A record, artefact, observation or reproducible result that supports a claim. Evidence must be attributable, current enough for the decision and protected according to sensitivity.
Core principles
DXPS principles guide proportionate implementation.
Tasks define quality
Experience is evaluated through the outcomes people need to complete, not visual preference alone.
Access is foundational
Keyboard, assistive technology, contrast, semantics and responsive use are designed into the full page.
Performance is experiential
Loading, interaction and stability are measured in representative conditions and in the field where possible.
Clarity prevents failure
Content, labels, errors and recovery routes help people understand state and next action.
Measurement respects people
Analytics are proportionate, transparent and minimized rather than treated as unlimited collection.
Variation is expected
Devices, languages, connections and user needs are tested as real operating constraints.
Normative control set
Mandatory DXPS requirements.
Every applicable requirement shall be addressed for the declared scope. Alternative control designs may be accepted only when they produce an equivalent, evidence-supported outcome and do not conflict with the requirement. Assessors sample both design and operation and may request additional evidence where a material risk or inconsistency appears. Each control needs an accountable owner, affected boundary, review trigger and exception path; evidence must be attributable to the assessed version or operating period.

- DXPS-9.1
Continuous monitoring
The organization shall assign owners and thresholds for accessibility, experience, performance and content regressions after release. Evidence: monitoring cadence and issue records.
Required evidence
Evidence must support the claim being assessed.
An applicant should provide the smallest sufficient evidence set rather than an uncontrolled data dump. Records should show who made a decision, what boundary and version it concerned, what result was observed and how exceptions were handled. Sensitive technical, employee or customer material remains protected and is not published merely because it supports assessment.
- User research and priority-task catalogue
- Information-architecture and usability findings
- Responsive viewport and input matrix
- Keyboard, focus and assistive-technology tests
- Contrast and semantic review
- Content and error-state evidence
- Localization register
- Performance budgets and Core Web Vitals evidence
- Network resilience and asset reports
- Privacy-aware measurement and monitoring records
Assessment and certification
Certification is a controlled decision, not an automatic badge.
The programme confirms the applicant and scope, reviews submitted evidence, performs a technical assessment and records findings. The applicant responds to nonconformities with cause, correction and evidence of effective action. A certification decision is separated from evidence preparation as far as the programme's current operating model permits. Surveillance and renewal consider continuing control operation and material change.
Conformance levels
The declared scope has accountable ownership, a documented baseline and an implementation plan. Foundation is a readiness state, not certification.
Required controls and evidence have been reviewed against the selected standard, with identified nonconformities recorded and corrective actions accepted.
A formal conformance decision has been issued through the EC TECH programme after scope confirmation, evidence review, technical assessment and closure of blocking nonconformities. Certification is neither automatic nor external accreditation.
Nonconformity levels
A condition that does not presently breach a mandatory requirement but could weaken consistency, evidence quality or future conformance if left unattended.
A contained failure to meet a requirement where the control system remains substantially effective. Closure requires proportionate correction and evidence accepted by the programme.
A missing, systemic or materially ineffective control, or a condition that creates unacceptable risk for the declared scope. Certification cannot be granted or maintained until satisfactory corrective action is verified.
Relationship to established frameworks
DXPS uses informed alignment without false equivalence.
These references help applicants deepen controls or compare terminology. “Informed by” means a source influenced the requirement design; “maps to” means a documented relationship can be shown; “aligned with” indicates compatible outcomes. None of those phrases means “certified to”. An external framework or law retains its own scope, text, assessment route and authority.
W3C WCAG 2.2
Its technology-independent success criteria inform the accessibility target and full-page verification approach.
Google Core Web Vitals
Current LCP, INP and CLS guidance informs experience measurement and recommended thresholds; DXPS does not guarantee search ranking.
ISO/IEC 25010:2023
Its product-quality model informs usability, performance efficiency, reliability and related quality thinking.
Web platform standards
Semantic HTML and platform accessibility behavior provide the implementation foundation; conformance depends on the complete rendered experience.
Implementation pathway
A practical 30/60/90-day adoption sequence.
The sequence is a planning aid, not a promised certification timetable. Complexity, evidence maturity, third-party access and corrective work determine the real path. Teams should prioritize material risk and sustainable operation rather than creating documents that exist only for assessment day.
First 30 days — define the experience
- Name priority users and tasks
- Baseline accessibility and responsive behavior
- Measure representative performance
- Inventory content, errors and analytics
Days 31–60 — remove critical friction
- Repair navigation and semantics
- Resolve keyboard and contrast barriers
- Apply performance and asset budgets
- Improve failure and slow-network recovery
Days 61–90 — validate and monitor
- Run representative usability and assistive tests
- Review localization and technical SEO
- Collect operating evidence
- Submit a bounded experience for assessment
Benefits
What disciplined adoption can improve.
- A shared definition of usable and measurable experience quality
- Fewer accessibility and responsive regressions
- Performance decisions connected to real user outcomes
- Clearer content and recovery behavior
- Evidence that supports procurement and continual improvement
Limitations
What certification does not prove.
- Conformance does not guarantee conversion, satisfaction or search position
- Automated accessibility tests cannot replace manual and assistive interaction
- Field performance varies by device, network, geography and third parties
- DXPS certification is independent and not W3C, Google or ISO accreditation
Versioning and change control
Current version: DXPS 26004:2026.
This page represents the current published 2026 version. Proposed changes are evaluated for need, clarity, measurable effect, compatibility and transition impact. A future revision will identify material changes and whether previously assessed scopes need additional evidence. Editorial clarification does not silently weaken a mandatory requirement, and an applicant cannot select an obsolete clause solely to avoid a current control.
Last reviewed: 6 September 2026. Public revision history will be linked when a subsequent revision exists; no empty or fictional history is presented.
