The International Professional Practices Framework (IPPF) and underlying International Standards for the Professional Practice of Internal Auditing (Standards) provide guidance to the internal audit activity. The Standards are applicable to all internal audit departments regardless of size, level of resources, complexity, or objectives and scope. Small audit activities face some unique challenges when implementing the Standards. Typically, a small audit activity has one or more of the following characteristics:
- One to five auditors
- Productive internal audit hours below 7,500 a year
- Limited level of co-sourcing or out-sourcing
Standards with a High Degree of Challenge for Small Audit Activities
The Practice Guide notes the following standards for which small internal audit activities face a high level of challenge when implementing:
- 1100 – Independence and Objectivity
- 1300 – Quality Assurance/Improvement Program
- 2000 – Managing the Internal Audit Activity
- 2200 – Engagement Planning
- 2300 – Performing the Engagement
These challenges are most likely to affect small internal audit activities, but they may affect internal audit activities of any size. This paper will review each of these standards, identify challenges to meeting the standard, and provide guidance to mitigate these challenges.
1100 - Independence and Objectivity
Standard: The internal audit activity must be independent, and internal auditors must be objective in performing their work.
Challenge: Auditors may have operational responsibilities such as records management, compliance, IT security, risk management, or other finance and accounting activities. The Chief Audit Executive (CAE) may report to an individual who has direct responsibility for areas that are subject to audits.
Guidance: Internal audit should explain to the board the difficulties involved with auditing areas where operational responsibilities or chain of command cause independence issues. They should recommend alternatives for audits such as, using external resources, and verifying only auditors that are not involved with the operational activity complete and review the audit. The CAE should discuss any challenges relating to the reporting structure or operational duties with the board and/or senior management when establishing the audit plan. If internal audit issues a report where there is a lack of independence and objectivity, the audit report must disclose this condition along with the related impacts.
1300 – Quality Assurance/Improvement Program
Standard: The CAE must develop and maintain a quality assurance and improvement program that covers all aspects of the internal audit activity.
Challenge: Lack of financial resources may limit the ability to perform an external or internal quality assessment (QA) in accordance with the Standards. The performance of an internal QA may be challenging due to time and staff constraints.
Guidance: Small organizations may use peer organization reviews or self-assessment with external validation to satisfy the external QA requirement. These approaches will have a lower monetary cost but will require a larger amount of internal audit staff hours. Organizations may consider utilizing employees outside of the internal audit activity for internal assessments if they have prior audit experience or QA training.
