Which of the following IT governance practices would BEST support IT and enterprise strategic alignment?

While an updated IT communication plan is important for disseminating information, it doesn't directly ensure strategic alignment at the decision-making level.

External consultants reviewing the IT portfolio can provide valuable insights, but their involvement is typically periodic and advisory, lacking the continuous strategic oversight and decision-making authority of internal senior management.

Strategic alignment requires close collaboration and oversight from the highest levels of the organization. When senior management regularly reviews the IT portfolio, they can directly ensure that IT investments, projects, and services are directly contributing to and supporting the overall enterprise strategy, making necessary adjustments to maintain alignment.

Periodically updating IT service level agreements (SLAs) is crucial for operational performance and service quality, but it addresses tactical service delivery rather than strategic alignment of the entire IT portfolio with business objectives.
