Abstract

Purpose: This study aims to conduct a systematic literature review on the concept of Combined Assurance, focusing on its origins, evolution, and the recommended steps for implementing this process within organizations.

Theoretical/Methodological Approach: The research was based on a systematic review of articles indexed in the Capes, Emerald, Web of Science, and Scopus databases. The analysis enabled the mapping of the conceptual development of Combined Assurance and the identification of key practices and guidelines for its implementation.

Findings: The results indicate that the concept of Combined Assurance originated in South Africa, specifically in the King II Report on Corporate Governance for South Africa (2002). The study identified the main steps for adopting the model: (i) establish a mature risk management framework; (ii) raise awareness about Combined Assurance; (iii) appoint a program leader; (iv) develop a structured strategy; and (v) map assurance providers and consolidate assurance results.

Contributions: This study offers a systematized theoretical foundation for professionals, researchers, and institutions interested in implementing Combined Assurance, providing a practical roadmap for its application. The research also highlights that the model enhances internal control environments and mitigates risks, including accounting fraud, thus promoting greater institutional integrity and sustainability.

Originality/Relevance: The topic remains underexplored in most Brazilian organizations, making this review a relevant contribution to the advancement of corporate governance and sustainable institutional management practices.
