Voice of the Customer initiatives provide direct customer evidence about the experience being delivered, making B the correct answer.
Operational measures can show whether a service met response times, resolution targets, availability levels, or other technical objectives. However, those measures cannot independently establish how customers perceived the service or whether the interaction created unnecessary friction. VoC mechanisms capture customer perspectives and allow the organisation to identify expectations, pain points, satisfaction drivers, and opportunities for improvement.
VoC does not eliminate perception measurement; it is itself a major mechanism for understanding perception. It is not concerned solely with operational efficiency, and it does not replace appropriate customer-experience training. Instead, VoC complements performance information by introducing the customer's perspective into decisions.
SDA v9 places greater emphasis on customer experience, Voice of the Customer, outcome-based measurement, and proactive customer engagement. Modern service management must move beyond operational dashboards and understand whether services actually work for the people relying on them. Accordingly, VoC is essential because a CX programme needs evidence from customers themselves rather than relying exclusively on internal performance assumptions.
