Is ISO 10002 mandatory?

No. ISO 10002:2018 is a guidelines standard, not a certifiable management system standard. It is widely used as a reference framework for complaint handling and is referenced in many regulatory and industry codes.

How is 'closing the loop' defined?

In NPS practice (Reichheld, Bain & Company), closing the loop means contacting the customer who gave feedback to acknowledge, investigate, and report back. ISO 10002:2018 §7.7 frames it as 'communicating the decision' to the complainant.

What is a realistic baseline for response coverage?

Specific benchmarks vary widely by industry and channel; we do not cite a universal number because credible cross-industry baselines for closed-loop coverage are scarce. Operators should baseline their own data before setting targets.
