Standards
We pride ourselves on the quality of our work and our objective is to provide tangible value to our Clients. We follow various standards and guidelines like the Institute for Internal Auditors (IIA) Standards, COBIT, FIDIC Framework, Public Finance Management Act, etc.
Our team is highly qualified, all members of the IIA and is also committed to the IIA’s Code of Ethics.
Work ethics
The years that we have retained our clients is testimonial of our commitment and exceptional service. We believe that what clients truly value is sound technical advice, delivery in the context of their business or commercial situation which is also practical, effective and implementable.
This requires going beyond the conventional Internal Audit to understand the underlying business transactions and the business imperatives and then applying an understanding of the control, contractual and regulatory framework to fashion a solution that works.
We equally believe that we will gain and retain our clients’ confidence only when we are able to provide efficient cost planning solutions consistently, from engagement to engagement, from one year to the next.
