What is most likely to cause a loss of faith in the Service Level Management process?

Measurements that align with customer perception of service quality reinforce trust, as they demonstrate the provider understands and tracks what matters to the customer.

Clear, concise, and unambiguous SLA wording improves mutual understanding and reduces disputes, which strengthens rather than weakens faith in the process.

When SLA targets are unmeasurable, neither the provider nor the customer can verify whether commitments are being met, creating ambiguity and suspicion about service performance reporting. This directly erodes confidence in the SLM process because the fundamental purpose of an SLA - providing an objective, verifiable agreement - is undermined by metrics that cannot be tracked or validated.

Involving customers in drafting Service Level Requirements increases ownership and buy-in, making customers more likely to trust the resulting SLAs.
