Effective oral and written communication is an essential professional competency for internal auditors because engagement work requires auditors to obtain information, discuss risks and controls, communicate observations, and present conclusions clearly to management and other stakeholders. Individual auditors are not required to possess expert-level knowledge of every matter that could affect an engagement; the internal audit function collectively must obtain the competencies necessary to complete its responsibilities. Likewise, auditors need sufficient knowledge of fraud risks to recognize indicators and evaluate how fraud is managed, but they are not all required to possess the expertise of fraud investigators. Professional competency therefore combines technical knowledge, business understanding, judgment, and communication skills appropriate to assigned responsibilities.
