Facilitating internal auditors in upholding their objectivity within the internal audit manual can effectively be addressed by ensuring that internal auditors regularly attend professional workshops to refresh and update their understanding of internal audit norms and concepts. This practice helps maintain a high level of professionalism and objectivity by keeping auditors informed about the latest standards and ethical guidelines, which in turn minimizes the risk of biases and enhances their ability to perform independent and objective audits.
