Introduction

Customer satisfaction is a measure of how well a company's products, services, and overall experience meet or exceed customer expectations. It is a key indicator of customer loyalty, retention, and business success.

Satisfied customers are more likely to repurchase, recommend the company to others, and be less price-sensitive. Understanding and improving customer satisfaction is therefore critical to long-term profitability.


Understanding Customer Satisfaction

Satisfaction = Perceived Performance - Expectations

If Performance > Expectations → Delighted customer

If Performance = Expectations → Satisfied customer

If Performance < Expectations → Dissatisfied customer

The Expectation-Disconfirmation Model

Customers form expectations before purchase and then compare actual experience against those expectations:

  • Positive disconfirmation: Performance exceeds expectations
  • Confirmation: Performance meets expectations
  • Negative disconfirmation: Performance falls short

Measurement Methods

Key Metrics

MetricQuestionScale
CSATHow satisfied are you with [experience]?1-5 or 1-10
NPSHow likely to recommend to a friend?0-10
CESHow easy was it to [complete task]?1-7

Net Promoter Score (NPS)

Measures customer loyalty based on likelihood to recommend:

  • Promoters (9-10): Loyal enthusiasts who will fuel growth
  • Passives (7-8): Satisfied but unenthusiastic
  • Detractors (0-6): Unhappy customers who can damage brand

NPS = % Promoters - % Detractors

Range: -100 to +100

Customer Effort Score (CES)

Measures ease of interaction, based on research showing that reducing customer effort increases loyalty more than delighting customers.

Survey Best Practices

  • Keep surveys short and focused
  • Ask at relevant touchpoints (post-purchase, post-support)
  • Include open-ended questions for insights
  • Ensure representative sampling
  • Close the loop on feedback

Satisfaction Drivers

Key Drivers Across Industries

  • Product/Service Quality: Core offering meets needs
  • Price/Value: Fair pricing for value received
  • Convenience: Ease of purchase and use
  • Customer Service: Helpful, responsive support
  • Reliability: Consistent performance
  • Personalization: Tailored experiences

DelightersUnexpected; creates delightNot expected, but highly valued when present

Improving Customer Satisfaction

Strategies

  • Set realistic expectations: Don't overpromise
  • Deliver consistently: Reliability builds trust
  • Listen and act on feedback: Close the loop
  • Empower employees: Enable them to solve problems
  • Personalize experiences: Make customers feel valued
  • Recover well: Great service recovery can increase loyalty

Service Recovery

The "service recovery paradox" suggests customers who experience a problem that is well-resolved can be more loyal than those who never had a problem.
