Which of the following is a PRIMARY responsibility of the CIO when an enterprise plans to replace its enterprise resource applications?

Reviewing the IT application portfolio is an important ongoing task, but ensuring architectural fit is a more direct and primary responsibility *during* a replacement project.

Evaluating and selecting application vendors is often a collaborative effort involving various stakeholders, and while the CIO has input, it's not their *primary* or sole responsibility compared to architectural oversight.

A CIO holds the strategic responsibility for the enterprise's technology vision and infrastructure. Ensuring that new enterprise resource applications comply with and fit into the existing or planned IT architecture requirements is crucial for system integration, data flow, security, and long-term strategic alignment. This prevents siloed solutions and technical debt, ensuring the new applications support the enterprise's future state.

Establishing software quality criteria is a critical aspect of system acquisition, but it's often a responsibility shared with IT management and project teams, with the CIO providing strategic direction rather than primary criterion establishment.
