Changes to the IT strategy must consider their impact on the enterprise architecture (EA), as the EA defines the structure and standards that enable strategy execution. The CGEIT Review Manual 8th Edition highlights that assessing EA impact is the greatest consideration to ensure that strategic changes are feasible and sustainable.
Extract from CGEIT Review Manual 8th Edition (Domain 4: Strategic Management):"When modifying the IT strategy, the CIO’s greatest consideration is assessing the impact on the enterprise architecture, as the EA provides the blueprint for IT capabilities, processes, and standards. Misalignment with EA can lead to implementation challenges and reduced effectiveness." (Approximate reference: Domain 4, Section on Strategy and EA Alignment)
Assessing the impact to the enterprise architecture (option B) ensures that the IT strategy leverages existing capabilities and addresses any architectural gaps, making it the most critical consideration.
Why not the other options?
A. Have key stakeholders been consulted?: Stakeholder consultation is important but secondary to ensuring the strategy is technically feasible via EA alignment.
C. Have IT risk metrics been adjusted?: Risk metrics are adjusted as part of risk management, not the primary concern for strategy changes.
D. Has the investment portfolio been revised?: Portfolio revision follows strategy and EA alignment to ensure investments support the updated strategy.
