This paper shows how auditor-general’s offices (AGO) use strategic planning to legitimize value-for-money (VFM) audits. The transformation of VFM audit practice through these planning processes (corporate plan, annual plan and annual report) involves several key actions by AGOs, including the development of VFM audit methodologies and cultivating relationships with the wider audit environment. IMPACT: This paper extends the existing international understanding about how value-for-money (VFM) audit/performance audit was added to the audit portfolio of the auditor-general’s office (AGO) in a specific country context. VFM audit is unique to AGOs, but its operationalization is different from AGO to AGO. AGOs can use the technical competence of VFM audit to stand out from private sector accounting firms.
