Experience Excellence Index (EEI)

Don’t guess your experience maturity. Measure it.

The world’s most rigorous organisational assessment for Customer, Digital Customer, Employee and Patient Experience — built on international standards, powered by structured evidence, and the gateway to global recognition.

What is the EEI

The definitive measure of experience excellence

A structured organisational maturity benchmark that replaces opinion with evidence, assumptions with data, and guesswork with a clear score out of 100 — across Customer, Digital Customer, Employee and Patient Experience.

01

Structured Assessment

120 diagnostic questions per discipline, each with defined evidence requirements and a five-point maturity scoring model. No opinions. No assumptions.

02

Research-Led, Beyond the Standard

The EEI sits a level above our international standards. Developed from years of global research and best practice — the rigour that also underpins ICXS, IDCXS, IEHWS and IPEXS — it measures not whether you meet a baseline, but how mature and excellent your experience capability truly is.

03

Evidence-Led Scoring

The QERE methodology ensures every score is justified by documented evidence, not self-assessment or survey sentiment — validated by accredited assessors.

04

Awards Gateway

Automatic entry into the global Experience Excellence Awards programme.

Why it’s different

This is not another survey

Most benchmarks rely on perception surveys, self-assessment or consultant opinion. The EEI measures what your organisation actually does — the systems, governance, culture and capabilities that deliver experience excellence.

What the EEI is not

  • A customer satisfaction survey (NPS, CSAT)

  • A self-assessment questionnaire

  • Based on consultant opinion or panel voting

  • Sentiment dressed up as measurement

What the EEI is

  • A structured diagnostic of organisational capability

  • Evidence-validated by accredited assessors

  • Scored on a transparent 0–100 maturity index

  • Its foundations are in our published standards

Assessment methodology

The QERE framework

Every question in every assessment follows the QERE structure — ensuring consistency, transparency and evidence integrity across all four disciplines.

Q

Question

A precisely worded diagnostic question targeting a specific organisational capability, behaviour or system.

E

Explanation

The context and intent — what it measures, why it matters, and what good practice looks like.

R

Reasoning

The evidence-based rationale linking this capability to experience outcomes, performance and maturity.

E

Evidence

Defined evidence the assessor validates — documents, data, processes and observable behaviours.

Maturity model

Four levels of maturity

Every question is scored against a transparent five-point scale that maps to four progressive maturity levels — from reactive awareness to proactive, systemic excellence.

Level 01

Reactive

No formal structure. Responses are ad hoc, inconsistent and personality-dependent. Outcomes are unpredictable.

Level 02

Aware

Recognition that experience matters. Early-stage processes emerging but inconsistently applied. Pockets of good practice.

Level 03

Structured

Formal systems across the organisation. Consistent governance, measurement and accountability. Experience is managed strategically.

Level 04

Proactive

Systemic, embedded and continuously improving. Experience excellence is part of organisational DNA. Innovation is evidence-led and predictive.

Why get assessed

What your organisation gains

A clear, actionable picture of where you are, where the gaps are, and what to prioritise — backed by evidence your board can trust.

  • Know your true maturity score

A transparent 0–100 score across 12 pillars replaces guesswork with a clear, comparable benchmark.

  • Pinpoint where to invest

Pillar-by-pillar scoring reveals exactly which capabilities need investment — from governance to AI to loyalty economics.

  • Board-ready evidence

Every score is evidence-validated by an accredited assessor — structured proof your leadership team can act on.

  • Track progress year on year

Repeat assessments create a longitudinal maturity trajectory — proving impact and maintaining momentum.

  • Global benchmarking

Compare your maturity against organisations worldwide across sectors, regions and disciplines.

  • Qualify for global awards

Your EEI score is your automatic entry to the Global Experience Excellence Awards.

  • Accelerate transformation

A prioritised improvement roadmap aligned to international standards — not a generic consultancy output.

  • Demonstrate commitment

To customers, employees, patients, regulators and investors — measurable, serious commitment to excellence.
