The factors influencing audit duration include:

  • Scope and Objectives: The audit's scope and objectives impact its duration. Larger or more complex organizations require more extensive audits.

  • Resources: Adequate staff and audit tools can expedite the process, while resource shortages may cause delays.
  • Frequency: Routine internal audits are shorter compared to less frequent, comprehensive ones.
