There are two broad types of audits based on the method of conducting an audit:

Internal risk audit: An internal risk audit is done by an organisation’s internal team, which is not a part of the project. Usually, it can be a separate team from the audit department or people from the peer team or other projects. There is a tendency that internal audits are not taken seriously; however, the project manager must look at a risk audit as an opportunity to find the gaps and close them before they turn into serious threats and affect the project deliverables.

External risk audit: An external risk audit is done by a third-party agency, government or private agency that looks at the processes and procedures and rates the conformance and issue recommendations. External risk audits are critical in stakeholder management because the stakeholders get to hear an independent opinion of the project management.
