A project audit provides an opportunity to uncover issues, concerns and challenges encountered during the project lifecycle. Conducted midway through the project, an audit affords the project manager, project sponsor and project team an interim view of what has gone well, as well as what needs to be improved to successfully complete the project. If done at the close of a project, the audit can be used to develop success criteria for future projects by providing a forensic review. This review identifies which elements of the project were successfully managed and which ones presented challenges. As a result, the review will help the organisation identify what it needs to do to avoid repeating the same mistakes on future projects

Projects can undergo 2 types of Project audits:

• Regular Health Check Audits: The aim of a regular health check audit is to understand the current state of a project in order to increase project success.
• Regulatory Audits: The aim of a regulatory audit is to verify that a project is compliant with regulations and standards. Best practices of NEMEA Compliance Centre describe that, the regulatory audit must be accurate, objective, and independent while providing oversight and assurance to the organisation.
  Other forms of Project audits:

Formal: Applies when the project is in trouble, sponsor agrees that the audit is needed, sensitivities are high, and need to be able prove conclusions via sustainable evidence.

Informal: Apply when a new project manager is provided, there is no indication the projects in trouble and there is a need to report whether the project is as opposed to where its supposed to Informal audits can apply the same criteria as formal audit but there is no need for such a in depth report or formal report.
