INTERNAL AUDIT
Internal Auditing
Internal audit should do more than confirm whether controls are working. It should help management understand what is really happening in the business, where risks are developing, and where opportunities for improvement exist.
Pro Optima provides fully outsourced and co-sourced internal audit services, combining financial, operational, IT, ESG and SOX/ICOFR expertise. Our particular strength lies in complex operational environments, especially mining, where most of our auditors have mining or other technical backgrounds.
Our approach is deliberately different from conventional audit. Pro Optima has developed a range of proprietary methodologies designed to move internal auditing beyond routine compliance and towards practical, actionable insight. These include:
-
Start with Intuition Method (SWIM)
-
In-and-Out Audits
-
Implement Controls Before Audit Method (ICBAM)
-
Fraud and Error Detection Tests
-
Risk Materialisation Testing (RMT)
-
Live Consultative Auditing
These methodologies are described in The Gardener of Governance – A Call to Action for Effective Internal Auditing, co-authored by Pro Optima’s founder, Barrie Enslin. Published in 2025, the book has attracted international attention, including adoption in university curricula and interest in translation by academic institutions.
Our objective is simple: to make internal audit useful beyond the audit report. Through practical, commercially focused auditing, we help organisations strengthen governance, improve operational efficiency and sustainability, anticipate risks before they materialise, and turn audit insight into meaningful action.
What sets Pro Optima apart is the way our people approach an audit. Our auditors are trained to think independently, question what they see, understand the operational realities behind the numbers, and remain alert to opportunities to add value. In mining environments, this is reinforced by the technical and operational experience within our team.
The result is internal auditing that goes beyond the obvious — providing management with insight that can support better decisions, stronger controls and better business performance.
CONTRACT MANAGEMENT
Contract Management Consulting
With the growing reliance on outsourced services, effective contract management is critical to ensuring that agreed costs, services, standards and obligations are properly managed. Managing outsourced services is an increasingly complex and demanding area.
Pro Optima provides contract management consulting to help organisations evaluate and strengthen their procurement and contract management processes, systems and controls. Services can include reviewing contract management practices, assessing the adequacy of procedures and controls, and designing practical approaches to improve oversight and accountability.
Our personnel bring extensive experience in managing and reviewing outsourced service arrangements, with a focus on practical solutions that support effective contract management and value for money.
INTERNAL CONTROLS
Internal Control Consulting
Pro Optima provides internal control consulting to organisations seeking to design, develop or strengthen their control systems, from individual process controls to comprehensive control frameworks.
Effective internal controls can limit financial leakage, reduce the risk of fraud and error, and support the achievement of strategic objectives.
Our support can range from designing controls for a specific process to developing or enhancing an organisation-wide control framework.
SECOND LINE ASSURANCE
Second Line Assurance Services
Following the Three Lines model developed by the Institute of Internal Auditors (IIA), Pro Optima provides second-line assurance services to support management (first line) in implementing effective controls and risk management practices.
Key services include:
-
Verification of on-site service contractors’ invoices as part of continuous monitoring programmes at major mining companies
-
Evaluation of contracts and contract amendments before finalisation
-
ESG and compliance audits for leading mining companies
-
Independent assurance reviews for complex or specialised areas requested by management

Effective internal controls curb financial leakage
and support the achievement of strategic objectives.
