Which of the following BEST enables an enterprise to determine whether a current program for IT infrastructure migration to the cloud is continuing to provide benefits?

Key Performance Indicators (KPIs) are specific, measurable metrics used to track the performance and success of a program against its objectives, making them the best way to determine if a cloud migration program is continuing to provide benefits. KPIs can measure aspects like cost savings, performance improvements, uptime, agility, and resource utilization, directly reflecting the program's value delivery.

Total cost of ownership (TCO) is a financial calculation of all direct and indirect costs over an asset's lifecycle, which is useful for initial investment decisions but less effective for ongoing performance and benefits assessment.

Key risk indicators (KRIs) monitor the level of risk exposure but do not directly measure the benefits or value being delivered by a program.

Net present value (NPV) is a financial valuation method used for project selection and investment appraisal at the beginning of a project, not for continuous monitoring of benefits realization during an ongoing program.
