Seven institutional indices. One evidence standard.
A CFO may never log into the platform. A General Counsel will. A board member will read the PDF a director forwards them. This is that document — what is measured, why it matters, how it is scored, what evidence supports it, and what business outcomes it impacts.
The seven indices
EII™
The audited emotional intelligence of an organization across recognition, clarity, respect, ownership, consistency, and AI-assist integrity — measured per interaction and rolled to a composite.
Emotional intelligence is the single largest unpriced exposure on the income statement: it determines whether a customer is retained, whether a complaint becomes a regulatory event, and whether AI assist is trusted or rejected.
- Each interaction is scored 0–4 on six orthogonal dimensions (NuX v0.1 rubric).
- Reviewer notes attach as evidence to every score above the human-review threshold.
- Per-tenant calibration coefficients normalize for channel mix, business unit, and language.
- Composite EII = weighted mean of dimension scores, weighted by exposure value of the interaction.
- Transcript / call recording / chat log retained for life of engagement
- Reviewer identity, timestamp, and rubric version on every published score
- Inter-reviewer agreement sampled monthly; drift triggers re-calibration
- Reduction in escalation rate and regulatory complaint volume
- Increase in resolution-at-first-contact and CSAT-to-retention conversion
- Defensible AI deployment posture for board and regulator
HXI™
The end-to-end human experience handshake score across every channel and handoff a customer touches, from first contact to resolution.
Customers do not experience departments — they experience handoffs. HXI prices the cost of broken handshakes in revenue, retention, and brand exposure.
- Each handoff in a customer journey is scored on continuity, context preservation, and emotional carry-through.
- Journey-level HXI = harmonic mean of handshake scores (worst handoff dominates).
- Cross-channel correlation matrix surfaces which handoff combinations destroy the most value.
- Journey reconstruction from CRM, telephony, chat, and email systems
- Per-handoff timestamp, agent identity, and channel transition logged
- Customer-perceived continuity sampled via post-resolution micro-survey
- Identification of the three handoffs responsible for most attrition
- Quantified ROI of channel consolidation or staffing reallocation
- Board-ready exposure number for omnichannel investment cases
JII™
The structural integrity of a customer's full journey across channels — whether the promise made at acquisition is kept through onboarding, service, and renewal.
Most churn is not caused by a single failure — it is caused by accumulated journey debt. JII makes journey debt visible before it becomes lost revenue.
- Journeys are segmented into acquisition → activation → service → renewal phases.
- Each phase is scored against the promise set at acquisition (contract, marketing, sales commitment).
- JII = phase-weighted integrity score; phases that touch revenue events are weighted higher.
- Acquisition artifact (proposal, contract, marketing claim) captured at journey start
- Each phase scored against the documented promise, not a generic benchmark
- Promise-vs-delivery gap retained as evidence for renewal conversations
- Renewal probability uplift through pre-emptive journey repair
- Reduced legal exposure from undelivered acquisition promises
- Clear attribution of churn cause to acquisition, service, or product
ETS™
The density of trust established, eroded, and recovered across the lifetime of a customer or stakeholder relationship.
Trust compounds. Every interaction either deposits or withdraws. ETS is the balance sheet executives never see — until the relationship is lost.
- Each interaction is scored for trust deposit, neutral, or withdrawal against six trust signals.
- Recovery interactions (after a known failure) are weighted higher for both deposit and withdrawal.
- ETS = exponentially weighted moving average of trust signals over the relationship lifetime.
- Trust events tagged in interaction record with reviewer attribution
- Recovery context (root cause, remediation owner) attached to recovery interactions
- Trust trajectory visualized over relationship lifetime, not point-in-time
- Early warning of high-value relationships entering trust deficit
- Defensible prioritization of executive intervention
- Quantified link between trust trajectory and contract value at renewal
CCI™
Clarity and comprehension of language across cultures, accents, channels, and AI-generated text — measured for both operator and audience.
Clarity failures are the leading cause of repeat contact, escalation, and regulatory complaint. CCI prices the cost of every avoidable second interaction.
- Each interaction is scored on lexical clarity, pace, accent neutrality, and jargon density.
- Cross-cultural alignment is scored separately against the audience cultural register.
- CCI = composite of clarity, comprehension, and alignment; weighted by audience criticality.
- Transcript with per-segment clarity score and reviewer notes
- Audience cultural register captured from CRM / locale / language preference
- Repeat-contact correlation reported alongside score
- Reduction in repeat-contact rate and average handle time
- Lower regulatory complaint volume from misunderstood disclosures
- Quantified AI script and IVR clarity for buyer-facing surfaces
ECS™
The emotional comfort a customer or stakeholder experiences during cross-cultural and high-stakes interactions.
Discomfort is the leakage no spreadsheet captures. Customers who feel uncomfortable leave silently — ECS makes that silence measurable.
- Each interaction is scored on safety, dignity, recognition, and pace appropriateness.
- High-stakes interactions (complaint, dispute, bereavement, regulatory) are weighted higher.
- ECS = comfort composite, calibrated per cultural register and interaction type.
- Reviewer-tagged comfort signals with timestamps
- Customer cultural and situational context recorded at interaction start
- Comfort trajectory across interaction (not single-point) retained as evidence
- Silent-churn reduction through identification of low-comfort patterns
- Defensible cultural competence posture for regulated industries
- Board-ready brand-safety signal across global operations
CCA™
Cultural Congruence Alignment between operator and audience — measured at the cultural register, not the language level.
Speaking the same language is not the same as being culturally congruent. CCA prices the gap between linguistic and cultural delivery.
- Operator cultural register is profiled from interaction sample.
- Audience cultural register is captured from CRM / locale / declared preference.
- CCA = alignment score between operator and audience register, calibrated per market.
- Operator register profile retained with version and reviewer attribution
- Audience register source documented (declared, inferred, or CRM-confirmed)
- Alignment gap visualized per market and per operator cohort
- Identification of operator cohorts mismatched to highest-value markets
- Quantified ROI of cultural training and staffing reallocation
- Defensible market expansion plan with cultural risk priced in
Defensibility, not novelty.
Every NuX Holdings™ index above has the same answer to the only three questions that matter at a board table: What evidence produced this number? Who reviewed it? Can it be reproduced? If the answer to any is no, the score is not published.
