Detective's Memo: The revolutionary customer loyalty measurement method "NPS (Net Promoter Score)" published by Fred Reichheld in 2003. Many misunderstand it as merely a "0-10 point survey," but its true identity is a "leading indicator system that predicts revenue growth from behavioral predictions of recommendation intent." Why did Apple, Amazon, and Tesla abolish complex satisfaction surveys and focus solely on NPS? And why can a single question "How likely are you to recommend to friends/colleagues?" predict a company's future revenue? The quantification of word-of-mouth free marketing created by the three-way classification of Detractors (0-6 points), Passives (7-8 points), and Promoters (9-10 points). Uncover the true identity of this ultimate customer-centric management indicator that measures future behavior of recommendation rather than past emotions of satisfaction.
NPS (Net Promoter Score), formally known as the "Growth Prediction Indicator Based on Customer Recommendation Intent," is a customer loyalty measurement theory published by Fred Reichheld of Bain & Company in a 2003 Harvard Business Review paper. Using a single question "How likely are you to recommend this company/product/service to friends or colleagues? (0-10 points)," it classifies customers into Promoters (9-10 points), Passives (7-8 points), and Detractors (0-6 points), and is recognized among clients as a score (-100 to +100) calculated as "Promoter percentage - Detractor percentage." However, in actual practice, it is often superficially understood as a "simple survey," with most companies failing to understand its original strategic value: that recommendation intent predicts word-of-mouth and referrals as free marketing and strongly correlates with revenue growth rates.
Investigation Memo: NPS is not merely a "satisfaction indicator" but a "growth engine health check." Why are satisfied customers (7-8 points) ignored as "passives," and why does a 2-point difference between recommendation intent (10 points) and satisfaction (8 points) create a decisive difference in business growth? We need to clarify this modern business growth prediction foundation that converts the Happiness dimension of the HEART Framework into a single indicator and quantitatively measures the Referral of AARRR.
Basic Evidence: Customer Classification and Growth Prediction Through One Question
NPS Measurement Single Question:
"How likely are you to recommend [Company Name/Product Name/Service Name] to a friend or colleague?"
0 - 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - 9 - 10 Not at all likely Neutral Extremely likely
Why This Question is Revolutionary:
Problems with Traditional Satisfaction Surveys: - Many questions (20-50) - High response burden → Lower response rates - Complex results → No actionable insights - Satisfaction ≠ Repurchase/Recommendation
NPS Innovation: - Only one question → High response rate - Recommendation intent = Behavioral prediction - Clear classification → Immediate action guidelines - Proven correlation with growth rates
Detractors: 0-6 points
Characteristics: - Dissatisfied customers - Spread negative word-of-mouth - High churn (cancellation/departure) risk - Cause of brand damage
Behavioral Patterns: - Post critical reviews on SNS/review sites - Convey negative evaluations to friends/colleagues - Consider switching to competitors - Frequent complaints to customer support
Business Impact: - Hinder new customer acquisition (-1 person spreads bad reputation to 5-10 people) - Decline in brand image - Revenue loss from cancellations - Increased support costs
Response Priority: Highest (damage control/improvement)
Passives: 7-8 points
Characteristics: - Satisfied but not enthusiastic - Passive customers - Switch with attractive competitor offers - Rarely do word-of-mouth/recommendations
Behavioral Patterns: - No particular dissatisfaction but no special attachment - Switch if better alternatives exist - "Neither good nor bad" evaluation - No active recommendations or criticisms
Business Impact: - Zero contribution to growth - Stable but fragile revenue source - Risk of capture by competitors - No new acquisition through recommendations
Response Priority: Medium (elevation to promoters)
Important Insight: Satisfaction (7-8 points) ≠ Loyalty "Somewhat satisfied" is insufficient for growth
Promoters: 9-10 points
Characteristics: - Enthusiastic fans - Active word-of-mouth/recommendations - High repeat purchase rate - Brand Ambassadors
Behavioral Patterns: - Actively recommend to friends/colleagues - Post/share positively on SNS - Write high ratings on review sites - Early adoption of new products/features
Business Impact: - Free marketing (word-of-mouth/referrals) - Reduced Customer Acquisition Cost (CAC) - High LTV (Customer Lifetime Value) - Enhanced brand value
Response Priority: High (maintain/further delight)
Basic Calculation:
NPS = Promoter Percentage (%) - Detractor Percentage (%)
Example: 100 respondents - Promoters (9-10 points): 60 people → 60% - Passives (7-8 points): 20 people → 20% (not included in calculation) - Detractors (0-6 points): 20 people → 20%
NPS = 60% - 20% = +40
Score Range:
Minimum: -100 (all detractors) Maximum: +100 (all promoters) Neutral: 0 (promoters = detractors)
Actual Distribution: -100 to 0: Critical situation (urgent improvement) 0 to 30: Much room for improvement (below industry average) 30 to 50: Good (industry average level) 50 to 70: Excellent (industry top class) 70 to 100: Outstanding (world-class standard)
Industry Benchmarks (Reference Values):
Software/SaaS: 30-40 E-commerce: 40-50 Financial Services: 20-40 Telecom Carriers: 0-30 Airlines: 10-40 Hospitality: 40-60 Automotive: 30-50
Counter-intuitive but Rational Design:
Traditional Thinking: "7-8 points means satisfied customers, aren't they good?"
NPS Insight: "Satisfaction ≠ Recommendation/Growth Contribution"
Empirical Data: - 7-8 point customers' recommendation behavior: Nearly zero - 9-10 point customers' recommendation behavior: Frequent - Non-linear relationship between satisfaction and loyalty
Growth Contribution: - Promoters: +1 (new customer acquisition) - Passives: 0 (status quo only) - Detractors: -1 (customer loss/bad reputation)
Therefore: NPS = Growth Contributors (+1) - Growth Inhibitors (-1)
Evidence Analysis: The innovation of NPS lies in quantifying the impact of customer experience on revenue growth by measuring "recommendation intent" as future behavior rather than "satisfaction" as past emotion.

Promoter (9-10 points) Utilization:
Request for success story introduction
Advocacy Program:
Case study cooperation
Co-creation:
Effect: - New via word-of-mouth: 22% of total - CAC: -35% reduction - Brand value: Significant improvement
Warning File 1: Strong Correlation with Growth Rate
Fred Reichheld's research has proven a strong correlation between NPS and corporate growth rates. Within the same industry, companies with higher NPS have higher revenue growth rates, and data shows that when NPS exceeds the industry average by 10 points, the growth rate doubles.
Warning File 2: Quantification of Word-of-Mouth Free Marketing
Quantitatively measures the word-of-mouth effect where one promoter recommends to an average of 4-5 people, of which 1-2 actually make purchases. Enables new acquisition with zero CAC (Customer Acquisition Cost), dramatically improving marketing efficiency.
Warning File 3: Early Prediction of Churn (Cancellation)
NPS decline is a powerful leading indicator of churn. Detractors' (0-6 points) churn rate is more than 10 times that of promoters. NPS monitoring enables problem discovery and countermeasures before cancellation.
Warning File 4: Fostering Customer-Centric Culture Throughout Organization
A simple single indicator allows all employees (CEO to frontline) to share the same goal. Unlike complex satisfaction surveys, the clarity that everyone can understand and act on realizes organizational culture transformation.
Warning File 1: Response Bias Due to Culture/Language
The greatest danger. In Asian cultures like Japan, there is strong psychological resistance to giving "10 points," tending toward lower scores compared to Western cultures. Cultural adjustment is essential for international comparisons/benchmarks.
Warning File 2: Differences in Baseline Values by Industry/Product Type
Cannot compare telecom carriers (NPS: 0-30) and luxury hotels (NPS: 50-70) on equal terms. Comparison with industry benchmarks is important, but emerging industries lack benchmark data.
Warning File 3: Score Improvement Becomes End in Itself
Risk of forgetting true customer value creation as "NPS improvement" itself becomes the goal. Temptation to manipulate scores through improper means such as providing rewards/threats to respondents. Danger of falling into measurement for measurement's sake.
Warning File 4: Excessive Dependence on Single Indicator
NPS alone doesn't clarify "why" that score. Combination with free text fields/qualitative research is essential. Integration with other indicators like HEART Framework is important.
Warning File 5: Long-term Value Destruction Through Short-term Manipulation
Excessive discounts/benefits to raise NPS in short term → Profitability deterioration. Risk of rushing to superficial symptomatic treatment rather than fundamental product/service improvement.
Related Evidence 1: Integration with HEART Framework
Happiness × NPS: - Use NPS as main indicator of HEART's Happiness dimension - Multi-dimensional measurement with NPS + other HEART indicators - Integrated analysis of recommendation intent (NPS) + usage frequency (Engagement)
Integration Effect: Understanding both satisfaction and behavior
Related Evidence 2: Collaboration with AARRR Pirate Metrics
Referral × NPS: - Quantitatively measure AARRR's "Referral" with NPS - Promoter percentage → Prediction of word-of-mouth acquisition - NPS improvement → CAC reduction/growth loop acceleration
Retention × NPS: - NPS decline → Early churn prediction - Segment-specific NPS → Prioritization of retention measures
Integration Effect: Optimization of entire growth hacking
Related Evidence 3: Goal Setting with OKR
Goal Management × NPS: Objective: Improve customer loyalty Key Results: - Achieve NPS +50 or higher - Promoter percentage 60% or higher - Detractor percentage 10% or lower - Detractor→Promoter conversion rate 30% or higher
Quarterly NPS goal setting/achievement evaluation Organizational pursuit of NPS through OKR
Related Evidence 4: Measurement in Customer Journey
Customer Journey × NPS: - NPS measurement at each touchpoint - After first purchase - After onboarding completion - After support use - At contract renewal - Visualization of NPS trends throughout journey - Bottleneck discovery/improvement
Integration Effect: Time-series experience improvement
Related Evidence 5: Continuous Improvement with RCD Model
Learning System × NPS: - Record: Record NPS results/customer voices - Check: Score changes/trend analysis - Do: Improvement execution based on priorities
Implement NPS continuous improvement with RCD cycle

Related Evidence 9: Difference from Customer Satisfaction (CSAT)
CSAT (Customer Satisfaction Score): Question: "Were you satisfied with this service?" Response: 1-5 points or Very dissatisfied to Very satisfied
Characteristics: - Evaluation of specific transaction/experience - Measurement of past emotion - Timely/specific - However, weak correlation with future behavior
NPS: Question: "Likelihood to recommend?" Response: 0-10 points
Characteristics: - Evaluation of overall relationship - Prediction of future behavior - Strong correlation with growth rate - However, difficult to identify individual problems
Usage: CSAT: Individual experience improvement (support quality, etc.) NPS: Long-term loyalty/growth prediction
Integrated Use: Comprehensive measurement with both indicators
Related Evidence 10: Difference from CES (Customer Effort Score)
CES (Customer Effort Score): Question: "How much effort was required to solve the problem?" Response: Very easy to Very difficult
Characteristics: - Measurement of task completion ease - Direct evaluation of usability - Clear improvement points - However, emotional loyalty outside measurement
NPS: Measurement of emotional connection/recommendation intent
Usage: CES: Task efficiency/usability improvement NPS: Overall loyalty/delightful experience
Example: Banking app: - CES: Ease of money transfer task - NPS: Recommendation intent for bank overall
Related Evidence 11: Relationship with LTV (Customer Lifetime Value)
NPS → LTV Causal Relationship:
Promoters (9-10 points): - High repeat purchase rate - High upsell/cross-sell success rate - Low churn rate - LTV: Highest
Passives (7-8 points): - Standard purchasing behavior - Medium competitor switching risk - LTV: Average
Detractors (0-6 points): - Early cancellation/departure - Spread negative word-of-mouth - LTV: Lowest (actually negative)
Empirical Data: Promoter LTV = Detractor LTV × 10-20 times
LTV Maximization Strategy: NPS improvement → Promoter percentage increase → Overall LTV improvement
Related Evidence 12: Science of Response Rate Improvement
Industry Average Response Rate: 10-30% Excellent Company Response Rate: 40-60%
Response Rate Improvement Measures:
Avoid: - Weekends/early Monday morning - Late night/early morning - After time has passed since experience
Body: - Personalization (name/specific experience) - State time required ("1 minute") - Explain value of response (used for improvement) - Mobile optimization (easy on smartphone)
Caution: - Excessive incentives → Response bias - Rewards only to promoters → Induces fraud
Website pop-ups
Reminders:
Implementation Example: - Email sending: 24 hours after experience - Reminder 1: To non-responders after 3 days - Reminder 2: To non-responders after 7 days - Total response rate: Achieved 45%
Related Evidence 13: Segment Analysis Practice
Why Overall NPS Alone is Insufficient:
Example: Overall NPS = +30
Segment Analysis: - New customers: +10 (improvement needed) - Existing customers: +50 (excellent) - Paid plan: +60 (most excellent) - Free plan: +5 (major issue)
→ Discover problems invisible in overall average
Recommended Segment Axes:
Customer Attributes: - New vs Existing - Free vs Paid - Company size (B2B) - Industry (B2B) - Age/gender (B2C) - Region
Behavioral Data: - Usage frequency (Heavy/Light) - Feature usage status - Support usage presence - Purchase amount
Customer Journey: - During onboarding - Active usage - Dormant - Considering cancellation
Implementation: CRM/data warehouse integration Create segment-specific dashboard Regular segment analysis reports
Related Evidence 14: AI Utilization for Free Text Analysis
Challenge: NPS numbers alone don't clarify "why" Manual analysis of free text takes time
Solution: AI/NLP (Natural Language Processing) Utilization
Implementation: - Automatically classify free text - Positive/negative - By topic (features/price/support, etc.) - Extract frequent keywords - Sentiment analysis
Discovery Example: Main Topics of Detractors (0-6 points): - Topic 1: "support slow response" (28%) - Topic 2: "features complex hard to understand" (24%) - Topic 3: "price high cost-effectiveness" (18%)
→ Clear improvement priorities
Prompt Example: "Analyze the following 100 NPS detractor comments and provide the top 3 main complaints and improvement suggestions"
Effect: - Analysis time: Days → Minutes - Insight quality: Improved - Oversight risk: Reduced
Related Evidence 15: Building NPS-Driven Organizations
Level 1: Executive Commitment
Essential Elements: - CEO declares NPS as most important KPI - Regular NPS review in board meetings - Budget/resource allocation for NPS improvement - Exemplary behavior of "customer first"
Apple Example: - Tim Cook reviews NPS weekly - All executives have NPS responsibility - "Customer experience" at center of all strategy
Level 2: Company-wide KPI Implementation
Implementation: - Incorporate NPS into all department KPIs - Product: Product-specific NPS - Marketing: NPS of acquired customers - Customer Success: NPS of assigned customers - Support: Post-support NPS - Sales: NPS of closed customers - Reflection in employee evaluation/compensation - Bonus/promotion criteria
Caution: - Temptation to manipulate - Short-term optimization trap - Management with balanced scorecard
Level 3: Frontline Penetration
Practice: - Share NPS results at daily morning meetings - Listen to detractors' voices together - Immediate action decision on improvements - Motivation improvement with promoters' voices
Zappos Example: - All call center staff conscious of NPS - "WOW experience" creation as evaluation standard - Culture of sharing customer delight episodes
Level 4: Transparency/Visualization
Implementation: - Company-wide dashboard with public NPS - Real-time updates - Department/team/individual NPS - Ranking/gamification
Effect: - Healthy competition - Autonomous improvement actions - Horizontal deployment of success stories - Accelerated organizational learning
Related Evidence 16: Establishing Closed-Loop Culture
Closed-Loop Process: Customer Feedback → Immediate Response → Report to Customer → Re-measurement
Elements for Cultural Establishment:
Speed Emphasis: Rule: Contact detractors within 24 hours Reason: Delayed timing halves effectiveness Implementation: Automatic alerts/assignee allocation
Empowerment: Traditional: Wait for manager approval → Delayed response NPS Culture: Frontline judgment for immediate response Example: Ritz-Carlton
Immediate customer problem resolution
Learning/Sharing: Mechanism:
Integration into new employee training

Predicted Changes: - NPS becomes "real-time health diagnosis" - Customer experience prediction/optimization automated - Comprehensive loyalty measurement beyond NPS - Global/cross-cultural standardization
Investigator's Final Report:
NPS is "a revolutionary single indicator that predicts growth from customer recommendation intent." This theory published by Fred Reichheld in 2003 consolidates traditional complex satisfaction surveys into a single question and functions as a powerful framework that predicts corporate revenue growth rates through behavioral prediction of recommendation intent as future behavior.
What was most impressive in this investigation was the power of "just one question." The simple question "How likely are you to recommend to friends or colleagues?" can predict a company's future because recommendation intent strongly correlates with actual behaviors of word-of-mouth and referrals, becoming a growth engine as free marketing.
The scientific nature of the three-way classification of Promoters (9-10 points), Passives (7-8 points), and Detractors (0-6 points) was also an important discovery. The counter-intuitive design of ignoring satisfied Passives (7-8 points) as "not contributing to growth" is a rational judgment based on empirical data, showing the profound insight that "satisfaction ≠ loyalty."
Success cases of world-class companies like Apple (NPS: 72), Tesla (NPS: 96), and Amazon (NPS: 62) clearly prove NPS's practicality and effectiveness. By abolishing complex satisfaction surveys and focusing solely on NPS, the entire organization shares the same goal and customer-centric culture is fostered.
The importance of the Closed-Loop process (feedback → immediate response → report → re-measurement) was also confirmed as important practical knowledge. The empirical data that 35% of detractors convert to promoters through contact within 24 hours, problem resolution, and follow-up shows the value of integrating NPS not just as "measurement" but into "improvement actions."
Integration possibilities with other business frameworks were also confirmed. Utilization as the Happiness indicator of HEART Framework, Referral measurement of AARRR, specific KR setting in OKR - NPS functions as a foundation that clarifies the effectiveness measurement of other methods.
The 6-month practice case at a B2B SaaS startup also proves the theory's validity. NPS improvement from +4 to +32, churn rate reduction from 9% to 4%, ARR growth rate acceleration from +15% to +38% are proof that appropriate NPS utilization produces concrete business results.
However, at the same time, the risk of response bias due to culture/language emerged as an important warning. Psychological resistance to "10 points" in Asian cultures like Japan, difficulty in comparison with Western countries, is a challenge that internationally expanding companies inevitably face, and the need for cultural adjustment was recognized.
The risk of score improvement becoming an end in itself was also confirmed as a danger to overcome. The temptation to manipulate scores through improper means such as providing rewards/pressure, and the danger of forgetting true customer value creation, are pitfalls that NPS-implementing organizations must always be vigilant about.
The caution about excessive dependence on a single indicator was also recognized as a necessary limitation. NPS alone doesn't clarify "why," and combination with free text fields, qualitative research, and other indicators (HEART Framework, etc.) is essential.
Future evolution possibilities through integration with AI/machine learning were also confirmed. A future is visible where NPS evolves from "past measurement" to "future prediction/automatic optimization" through real-time measurement, predictive NPS, automatic improvement, emotion AI integration, etc.
The necessity of organizational culture transformation was also recognized as an important implementation condition. Through executive commitment, company-wide KPI implementation, frontline penetration, transparency/visualization, there is a need to foster a culture where NPS functions not just as a number but as the organization's behavioral principle.
The most important discovery is that NPS functions beyond a mere "satisfaction indicator" as a "system that fosters customer-centric management organizational culture." Through a simple single question, all employees can understand and empathize, and through clear classification of promoters/detractors, it leads to immediate action - this feasibility is why NPS became the world's most widespread customer indicator.
In the modern era where uncertainty, intensifying competition, and increasingly sophisticated customer expectations prevail, customers who are "somewhat satisfied" are insufficient. NPS presents a new paradigm of "increasing customers delighted enough to recommend," "utilizing word-of-mouth free marketing," and "building a sustainable growth engine," providing a revolutionary approach to customer-centric management.
Recommendation Maxim: "Satisfied customers say nothing, but delighted customers tell everyone. Growth comes from delight."
