Which of the following is the GREATEST advantage of maintaining an internal IS audit function within an organization?

Internal auditors operate within the organization continuously, allowing them to develop an intimate and comprehensive understanding of the business's specific processes, IT systems, culture, and strategic objectives, which enhances the relevance and practicality of their audit findings and recommendations.

While internal auditors interact with management, the ability to 'negotiate' recommendations is not the greatest advantage and can sometimes even be seen as a challenge to independence if not handled properly.

Increased staff visibility and availability throughout the year is a logistical benefit, but it is not the primary strategic advantage compared to the deep contextual understanding gained.

Internal auditors typically face more challenges to independence and impartiality compared to external auditors, making this a common drawback rather than a greatest advantage.
