When drafting a service level agreement what key element should be included so the provider and the customer can objectively determine whether commitments were met and take action if they were not?

Using vague language for performance expectations undermines the purpose of an SLA by making it impossible to objectively determine performance, thereby protecting neither the provider nor the customer in the long run.

Leaving out specified remedies or financial penalties for missed commitments diminishes the enforceability and accountability of the SLA, providing no recourse for the customer if the provider fails to meet agreed-upon service levels.

Specifying clear measurable performance metrics and thresholds is a key element in an SLA because it provides objective criteria (e.g., uptime percentage, response times, error rates) against which the provider's performance can be consistently evaluated. This enables both parties to unambiguously determine if commitments have been met and serves as the foundation for any agreed-upon remedies or penalties.

Neglecting to document escalation paths and communication procedures hinders timely resolution of issues and proper communication during service disruptions, making the SLA less effective in practice.
