Which of the following should be the CIO's GREATEST consideration when making changes to the IT strategy?

Consulting key stakeholders is important for buy-in, but it is a process aspect, not the greatest *technical* or *structural* consideration for the strategy itself.

When making changes to the IT strategy, the CIO's greatest consideration should be assessing the impact on the enterprise architecture (EA). The EA serves as the blueprint for how technology supports the business, and any strategic shift must be reconciled with, or update, the EA to ensure architectural integrity, avoid inconsistencies, and enable successful implementation across the organization.

Adjusting IT risk metrics is a consequence of strategic changes and part of the governance framework, but it is not the primary consideration during the formulation of the strategy itself.

Revising the investment portfolio is an outcome of a changed IT strategy and a key component of its implementation, but the assessment of architectural impact is more foundational to the strategy's viability.
