Performance evaluation and internal audit of the system

Is the asset management system itself audited, by people competent to audit it, on a programme derived from risk?

What goes wrong without it

Where an internal audit function exists, its asset management coverage is often limited to maintenance spend and procurement compliance, because those are the parts that look like the rest of the audit universe. The system itself, meaning the decision-making framework, the SAMP, the data, goes unexamined. The organisation is then assured about its transactions and unassured about the basis on which it spends billions.

What to examine

  • Read the internal audit plan and identify what proportion of assurance effort is directed at the asset base relative to its share of the balance sheet.
  • Check whether the audit programme considers the importance of the processes concerned and the results of previous audits, which the clause requires.
  • Establish whether the auditors are competent in asset management, or competent in audit and reading across.
  • Confirm management review inputs include what the standard specifies, and that outputs changed something.

Required by
