Which of the following roles should approve major IT purchases to help prevent conflicts of interest?

An IT steering committee typically comprises senior representatives from various business units and IT, providing a holistic perspective on IT investments. This committee's collective decision-making helps ensure that major purchases align with overall business strategy, provide organizational value, and that no single individual or department can push through purchases benefiting them inappropriately, thereby mitigating conflicts of interest.

While the CIO oversees IT, having a single individual approve all major IT purchases creates a potential for a conflict of interest or a lack of broader business perspective.

The Chief Compliance Officer primarily ensures adherence to laws and regulations, but is not typically responsible for operational approval of IT purchases.

The Project Management Office (PMO) provides governance and support for projects, but the ultimate approval for strategic IT purchases usually rests with a higher-level governance body.
