ACIO determines IT investment management processes are not fully realizing the benefits identified in business cases. Which of the following would be the BEST way to prevent this issue?

CIO review and approval of business cases occurs at the beginning and doesn't ensure benefits are realized throughout the project lifecycle.

Evaluating delegation of investment approval authorities addresses governance structure but not the ongoing monitoring of benefit realization for individual projects.

Stage-gate reviews provide periodic checkpoints where project progress, alignment with business cases, and continued viability are formally assessed by stakeholders. These reviews allow for early identification of deviations from planned benefits, risks, and scope creep, enabling timely corrective actions or even project termination, thereby preventing further investment in initiatives that are not realizing their intended value.

Documenting lessons learned is a post-project activity for future improvements and does not prevent issues in current projects from failing to realize benefits.
