The PricewaterhouseCoopers (PwC) approach to assessing internal audit quality and effectiveness includes a four-phase plan that follows the Internal Audit Framework.

Phase 1: Project planning
Includes defining the specific objectives, stakeholders and deliverables. Key to this phase is a clear and tailored set of objectives for the project overall. For many organizations, the deliverable will include not just a report on internal audit but an action plan to address any gaps noted.
Phase 2: Value driver identification
Includes interviews and surveys to gain insight and understanding of both the value drivers of internal audit stakeholders and perceptions of current performance.
Phase 3: Current state assessment
Includes detailed reviews and analysis of internal audit’s core processes. In this phase, Profiler™, PwC’s proprietary internal audit best practices benchmarking tool, is used to assess and benchmark the practices of an internal audit function. More importantly, Profiler also enables the identification of other possible best practices that may fit the specific value drivers of the organization. This phase also includes assessments of compliance with applicable professional standards.
Phase 4: Solution development
Includes the development of not only a report of findings and observations, but an action plan to implement the specific recommendations that appear to offer the highest value to the organization.
