An IS auditor is providing input to an RFP to acquire a financial application system. Which of the following is MOST important for the auditor to recommend?

An IS auditor's primary role is to ensure that systems support the organization's objectives and risks are adequately mitigated. Ensuring the application meets the organization's functional, technical, and security requirements, including control objectives, is paramount to its success and the organization's financial integrity.

Vendor employee background checks are important for supplier risk management but secondary to the core functionality and security of the application itself.

While audit trails are crucial for financial applications and should be included in the design, this is a specific requirement that falls under the broader category of 'meeting the organization's requirements'.

Supplier experience is a good indicator of capability but is less critical than the actual alignment of the proposed application with the organization's specific needs.
