Which of the following provides the BEST evidence that outsourced provider services are being properly managed?

An SLA with penalties is a good contractual element, but its mere existence doesn't prove that management is actively overseeing or enforcing it.

While historical performance data from the vendor is useful, it's merely a report; effective management requires taking action based on that data, especially for non-performance.

Aligning internal performance standards with corporate strategy is important for the organization itself, but it doesn't directly demonstrate the management of an *outsourced provider's* performance.

Taking adequate action for noncompliance with the SLA provides the best evidence of proper management because it demonstrates active oversight, enforcement of contractual terms, and a commitment to maintaining service quality. This proactive approach ensures that the outsourced provider remains accountable and that service expectations are consistently met.
