Overview

Most CX metrics rely on customers actively responding to a survey. NPS, CSAT, and CES all depend on a small, self-selected group of respondents. The majority of customers who have a good or bad experience never fill out a form, but they often do leave a review, post on social media, or describe their problem to a contact center agent.

oCX captures this broader signal. By analyzing feedback from every available source simultaneously, it produces a score that reflects the experience of a far larger and more representative sample of customers.

Key Facts
  • Developed by: Alterna CX
  • Score range: -100 to +100
  • Score above 0: Positive feedback outweighs negative feedback
  • Data sources: Reviews, social media, contact center transcripts, NPS, CSAT, support tickets, in-app feedback
  • Key difference from NPS: Does not require customers to respond to a survey
  • Updated: Continuously, as new feedback arrives
  • Supports: Location-level comparison, trend tracking, competitive benchmarking

What does the oCX score range mean?

oCX scores range from -100 to +100, structured similarly to NPS to make benchmarking familiar:

-100 to -1 Net negative
0 to 29 Acceptable
30 to 59 Good
60 to 100 Excellent

A score above 0 indicates that positive customer feedback outweighs negative feedback in aggregate. The score can be tracked over time, compared across locations or business units, and benchmarked against industry averages.

What data sources feed into oCX?

Unlike NPS, which relies on one question sent to a sample of customers, oCX draws from all available feedback channels simultaneously:

⭐ Online reviews
💬 Social media posts
📋 NPS surveys
📊 CSAT responses
📞 Contact center transcripts
🎫 Support tickets
📱 In-app feedback

This multi-source approach means the oCX score reflects input from customers who left a Google review, customers who posted on social media, customers who called support, and customers who responded to a survey — all in a single unified metric.

How does oCX compare to CSAT and CES?

CSAT and CES are both post-interaction survey metrics that capture satisfaction or effort at a specific touchpoint. Like NPS, they depend on customers responding to a survey after a defined interaction.

CSATPost-interaction surveyAfter a specific touchpointCustomers who don't respond to surveys
CESPost-interaction surveyAfter a specific touchpointCustomers who don't respond to surveys
oCXAll available feedback channelsContinuousCustomers who leave no feedback signal at all

oCX is not a replacement for CSAT or CES at the touchpoint level. It is a complementary metric that gives a continuous, cross-channel view of CX health alongside the precise interaction-level readings those metrics provide.

What does "observational" mean?

The term observational reflects the methodological distinction from solicited metrics. Rather than asking customers to rate their experience, oCX observes what customers actually say across the channels where they naturally express opinions.

This is the same principle used in observational research across fields: instead of asking people how they behave, you watch how they actually behave. In CX, instead of asking customers how satisfied they are, oCX measures what they say when no one is prompting them.

How do companies use oCX?

  • Location benchmarking: comparing oCX scores across stores, branches, or service centers to identify which locations underperform and why
  • Trend monitoring: tracking oCX over time to detect changes in customer experience before they appear in operational metrics
  • Root cause prioritization: using the topics driving the oCX score to rank operational improvements by their expected impact
  • Competitive benchmarking: comparing oCX scores against publicly available competitor feedback to understand relative position
  • Executive reporting: a single, intuitive score that summarizes CX health across all channels for leadership reporting

Key takeaway: oCX, developed by Alterna CX, solves the core limitation of survey-based CX metrics: it captures feedback from customers who never fill out a form. By observing what customers say across reviews, social media, and contact center interactions, it produces a score that is broader, more continuous, and more representative than NPS, CSAT, or CES alone.

Frequently Asked Questions

What is oCX?
oCX, or Observational Customer Experience, is a customer experience metric developed by Alterna CX that scores the quality of customer experience on a scale from -100 to +100, based on real feedback observed from reviews, social media, contact center interactions, and other channels, rather than relying solely on survey responses. A score above 0 means positive feedback outweighs negative feedback in aggregate. Unlike NPS or CSAT, oCX does not require customers to respond to a survey.
Who developed oCX?
oCX was developed by Alterna CX, a customer experience analytics company. The metric was created to address the core limitation of survey-based CX metrics like NPS: that they only capture feedback from the small percentage of customers who respond to surveys, leaving the majority of customer sentiment unmeasured. Alterna CX introduced oCX as a way to measure CX from all available feedback signals simultaneously.
How is oCX different from NPS?
NPS is based on survey responses from customers who choose to respond, typically 10 to 30% of those contacted. oCX draws from all available feedback including unsolicited sources like online reviews and social media posts, giving a broader and more representative picture of the full customer base. oCX also surfaces the topics driving positive and negative sentiment automatically, explaining why the score is what it is without requiring separate analysis.
How is the oCX score calculated?
The oCX score is calculated by analyzing sentiment across all connected feedback sources, weighting the results by volume and source type, and producing a single score from -100 to +100. A score above 0 indicates that positive customer feedback outweighs negative feedback in aggregate. The score can be tracked over time, compared across locations or business units, and benchmarked against industry averages. The detailed calculation methodology is proprietary to Alterna CX.
What data sources feed into oCX?
oCX draws from multiple sources simultaneously, including online reviews, social media posts, NPS and CSAT survey responses, contact center transcripts, support tickets, and in-app feedback. The breadth of sources is what makes it more representative than a single-channel metric. This means the oCX score reflects customers who left a Google review, customers who posted on social media, customers who called support, and customers who responded to a survey, all in a single unified score.
How does oCX compare to CSAT?
CSAT measures satisfaction with a specific interaction via a post-transaction survey, capturing only those customers who respond. oCX measures satisfaction across all interactions simultaneously, using both solicited and unsolicited feedback from every channel where customers express opinions. CSAT gives a precise, interaction-level reading for survey respondents. oCX gives a continuous, representative reading for all customers who leave any feedback signal, regardless of whether they were ever asked.
How does oCX compare to CES?
CES (Customer Effort Score) measures the ease of a specific interaction via a post-interaction survey. It is a useful signal for identifying friction at a specific touchpoint, but it only captures customers who respond to the survey. oCX identifies friction patterns from all available feedback including contact center transcripts and online reviews, covering a far broader set of customer interactions without requiring any survey participation.
What does "observational" mean in oCX?
Observational refers to the methodological distinction from solicited metrics. Rather than asking customers to rate their experience through a survey, oCX observes what customers naturally say across the channels where they express opinions: review platforms, social media, contact center calls, and more. This is the same principle used in observational research: instead of asking people how they behave, you observe how they actually behave. In CX terms, instead of asking customers how satisfied they are, oCX measures what they say when no one is prompting them.
