Systems Control and Review Files (SCARF) are embedded audit facilities within computerized accounting systems. They consist of program code or additional data incorporated into the system by an auditor to provide robust oversight and control of financial transactions.
Historical Context
SCARF was developed in response to the increasing complexity of computerized accounting systems in the latter half of the 20th century. As businesses moved away from manual bookkeeping to digital systems, the need for effective internal controls and audit trails became paramount.
Types and Categories
SCARF is a specialized tool within the broader category of Continuous Auditing techniques. Other related categories include:
- Embedded Audit Modules (EAM): Similar to SCARF, EAMs are integrated into application systems to monitor specific types of transactions continuously.
- Integrated Test Facilities (ITF): A simulated data environment within a live system that allows auditors to test processes without disrupting normal operations.
Key Events
Key milestones in the development of SCARF include:
- 1960s-70s: Initial adoption of computerized accounting systems and the concomitant development of automated internal controls.
- 1980s: Development and formalization of SCARF as a structured audit tool.
- 2000s: Integration of SCARF within Enterprise Resource Planning (ERP) systems.
Detailed Explanation
SCARF works by creating designated audit files within a computerized system. The auditor can specify:
- Files as SCARF or Non-SCARF: Determining which files within the system require additional audit scrutiny.
- Monetary Thresholds: Only transactions above a specified value are recorded in SCARF files.
- Access Control: Contents of SCARF files can only be altered or deleted by external auditors, ensuring data integrity.
Diagrams
A simple diagram illustrating the SCARF process can be represented using Mermaid format:

Importance and Applicability
SCARF is critical in ensuring:
- Data Integrity: By preventing unauthorized alterations to audit files.
- Transparency: Allowing external auditors to independently verify transactions.
- Risk Management: Identifying anomalies and potential fraud.
Examples
Consider a company using SCARF to monitor transactions over $10,000. If an unauthorized $15,000 transaction occurs, it will automatically be logged into the SCARF file for auditor review.
Considerations
- System Integration: Ensuring SCARF is correctly integrated into the accounting software.
- Threshold Settings: Carefully setting thresholds to balance audit thoroughness and system performance.
Related Terms
- Continuous Auditing: An ongoing process of examining transactions.
- Data Analytics in Auditing: Using analytical tools to examine data trends and anomalies.
- Control Objectives for Information and Related Technologies (COBIT): A framework for developing, implementing, monitoring, and improving IT governance and management practices.
Comparisons
SCARF vs. ITF:
- Purpose: SCARF focuses on actual transactions, while ITF tests scenarios.
- Integration: SCARF is more passive, whereas ITF actively simulates.
Interesting Facts
- SCARF is often embedded within larger ERP systems like SAP and Oracle.
- Continuous development in data analytics is enhancing SCARF’s capabilities, providing even deeper insights.
Inspirational Stories
Large corporations have successfully detected and mitigated significant fraud through the diligent use of SCARF, safeguarding millions in potential losses.

FAQs
Q: Can SCARF be bypassed? A: SCARF is designed to be highly secure, but proper implementation and regular audits are essential to prevent potential bypass.
Q: Is SCARF applicable to small businesses? A: While more common in larger enterprises, small businesses can also benefit from SCARF to ensure robust internal controls.
