Which of the following BEST helps to ensure that IT standards will be consistently applied across the enterprise?

ERM reviews identify and mitigate risks but do not inherently ensure consistent application of IT standards across the enterprise.

Mandatory systems development training can improve skill sets but does not guarantee the consistent application of broader IT standards across all enterprise IT functions.

Business case reviews by a steering committee focus on strategic alignment and project approval, not the technical enforcement or consistent application of IT standards across the entire enterprise.

Enterprise architecture (EA) provides a holistic blueprint that defines the structure and operation of an organization, ensuring IT standards, policies, and principles are consistently designed, developed, and implemented across all projects and systems. It acts as a guiding framework for technology choices and system integration, leading to standardization.
