Today, customer satisfaction is much more than a score from an annual survey. In a market where customers have increasingly high expectations, a customer-focused approach is a strategic necessity.
But how do you ensure that customer satisfaction does not remain a one-off effort, but becomes a structural part of your organisation?
International standards exist to help organizations manage customer experience professionally: from clear customer promises to complaint handling and measuring feedback.
Within the ISO 10000 series, there are four standards that are often seen as the basis for organizations that want to systematically address customer satisfaction.
• NBN ISO 10001 — codes of conduct and customer promises
• NBN ISO 10002 — complaint handling
• NBN ISO 10003 — external dispute resolution
• NBN ISO 10004 — measuring and monitoring customer satisfaction
These four forms together constitute a logical whole:
promise → complaint → escalation → feedback & improvement
They are also often viewed as a package because they complement each other. ISO positions them as guidelines for customer satisfaction within quality management.
This standard helps you to formulate clear agreements about what customers can expect.
Consider:
• response times
• transparent communication
• service promises
• customer-focused behavioral principles
The result: trust and consistency in customer relationships.
Complaints are often the most direct sign of customer dissatisfaction. ISO 10002 offers an approach to handling complaints correctly and learning from them in a structured way.
This standard supports organizations in:
• a transparent complaints process
• clear responsibilities
• faster solutions
• improvement based on complaint analysis
ISO 10002 is a global benchmark for complaint management.
Sometimes a complaint cannot be resolved internally. ISO 10003 provides guidelines for external forms of conflict resolution, such as mediation.
This offers:
• extra protection for customers
• reputation management in complex cases
• a fair escalation procedure
This concerns a customer satisfaction guidance standard.
Improving customer satisfaction starts with understanding what customers experience.
ISO 10004 provides a framework for:
• satisfaction surveys
• feedback channels and data analysis
• trend reporting
• continuous improvement actions
ISO positions this standard as a guideline for monitoring and measuring customer satisfaction.
In addition to these four core standards, there are additional standards that further support customer-focused working, depending on your sector or context.
Some examples:
• NBN ISO 10008 — customer satisfaction in e-commerce and online transactions
• NBN EN ISO 18295 — quality in customer contact centers
• NBN EN ISO 9001 — customer-focused quality management as a broader basis
• NBN ISO 10018 — employee involvement in customer experience
These standards are particularly interesting for organizations that want to link customer satisfaction to broader processes such as digital services, customer service, or quality policy.
