When determining the audit universe, the CAE should consider components of the organization ' s strategic plan (Option 1), inputs from senior management and the board (Option 2), and results of exit interviews with departing employees (Option 4). These factors provide a comprehensive understanding of the organization’s objectives, risks, and areas needing attention. Views of competitors and business associates (Option 3) are not typically a direct consideration for the audit universe, as the focus is primarily on internal factors and direct stakeholder inputs.
