Barrie describes Rainer as "Passionate and energetic, freely sharing his knowledge of and insights into the internal audit profession - a wild thinker, provocative, and he continuously challenges the status quo, which is the hallmark of a true thought leader. He was the first internal auditor I encountered who has these qualities". Barrie Enslin, Founder, Managing Director - Pro Optima Audit Services (Pty) Ltd (Pro Optima) Bachelor of Accounting Science (North-West University, Potchefstroom, South Africa) - 1984 Certified Internal Auditor (TheIIA) - 1993 https://www.linkedin.com/in/barrie-enslin-6934621b/ benslin@prooptima.co.za Barrie has five years of accounting and 35 years of internal audit experience, both in South Africa and internationally. He identified the need for operational audits in the mining industry and decided in 1997 to start Pro Optima. Five of the eight biggest mining companies in South Africa now count under Pro Optima's clients. Services provided include internal audit outsourcing and co-sourcing, second line assurance services, business process analysis, and other consulting work. Pro Optima has contributed over 2.5 billion South African Rands (ZAR), i.e., ±USD 170 million (considering exchange rate fluctuations) in quantified value added to its clients, with approximately 40% of its projects showing significant quantified value adding, mostly recoupment and prevention of overpayments to vendors and institutions, reduced pricing, curbing of wasteful spending, and improved efficiencies. Rainer describes Barrie as follows: "The Pro Optima success story is attributable to the team leveraging on the often-unexploited power of internal auditing. Barrie is pragmatic, does not stick to the script, and aspires to seek a fine and healthy balance between a systematic approach and the freedom to be creative. I believe Pro Optima's unorthodox approach is key in providing the much-needed value adding services to its clients." Rainer and Barrie met first at the ECIIA 2019 conference in Luxemburg. Rainer was speaking about "WRAPS - How to make better decisions." The duo soon realized their views on internal auditing were very similar and identified the need for practical guidelines to effective internal auditing, which they started with in January 2024. While writing this book it became even clearer how similar their thinking is. Although they did not agree beforehand about any of the specific content, their contributions dovetail superbly.
