Overview of operational auditing
Operational audits help businesses assess operational efficiency, control risks, and improve internal processes. In the context of rising costs and demands for transparency, regular audits help detect problems early, optimize resources, and enhance governance effectiveness.
Operational audits go beyond simply reviewing financial data; they also assess processes, policies, personnel, and technology, providing reliable data for management to make strategic decisions and enhance credibility with partners and regulatory bodies.
What is performance auditing?
Operational auditing is the process of comprehensively evaluating and analyzing a company's operations to determine its effectiveness, compliance, and ability to achieve strategic goals. Unlike financial auditing, which focuses on accounting data, and compliance auditing, which emphasizes legal aspects, operational auditing expands its scope to include performance, processes, and risk management.
In businesses, operational audits help identify weaknesses in processes, detect waste and potential risks, and then provide recommendations for improvement. This ensures that the business operates efficiently, transparently, and sustainably.
The role of operational auditing in businesses.
Performance auditing plays many important roles, including:
- Identifying waste and errors: Auditors conduct a comprehensive assessment of processes, helping businesses optimize resources and reduce operating costs.
- Supporting strategic decision-making: Data from performance audits provides an objective basis for management in long-term strategic planning.
- Increased transparency and credibility: An effective internal control system helps businesses build trust with shareholders, partners, and regulators.
- Improving internal processes: Auditors not only identify problems but also advise on process improvements and enhance operational capabilities.
Objectives of performance audit
The main objectives of performance audits include:
- Ensuring efficient resource utilization: Auditing helps identify unreasonable expenses, optimize budgets, and optimize human resources.
- Risk and error control: Identifying operational gaps helps businesses proactively prevent risks.
- Process improvement: Providing solutions to optimize processes, increase productivity, and improve work efficiency.
- Enhancing transparency: Ensuring that activities are conducted openly and transparently, meeting legal requirements and industry standards.
Legal basis related to performance auditing
To ensure that operational audits are conducted accurately and effectively, businesses need to base their audits on legal regulations and industry standards. These legal frameworks help determine the scope, methods, and responsibilities of the audit, while also ensuring reliable audit results that meet management requirements.
| No. | Legal basis | The main content relates to Operational Auditing. | Notes / Applications |
| 1 | Law on State Audit (Objectives, tasks, and responsibilities) | Regulations define the scope, subjects, principles, and content of performance audits (audits of economy, efficiency, and effectiveness). | It is the highest legal basis for performance auditing in the public sector in Vietnam. |
| 2 | Vietnam Auditing Standards System (VSAS) | Specific guidance on the objectives, scope, methods, and procedures for conducting performance audits (usually based on INTOSAI standards). | This is the primary professional standard for conducting performance audits in Vietnam. |
| 3 | International Auditing Standards (ISSAI) – Specifically ISSAI 3000-3999 | Provides an international guidance framework for Performance Audit/Value for Money Audit, including planning, implementation, evidence, and reporting. | Apply international best practices to develop and implement project implementation plans, especially for projects funded by ODA or involving international partners. |
| 4 | Documents related to project/program management and evaluation. | Decrees and decisions of the Prime Minister stipulate the evaluation of the effectiveness of public investment, the evaluation of national target programs or specific development projects. | Providing economic, efficiency, and effectiveness criteria for auditors to use in their evaluations. |
Scope of application of performance audit
To implement effective operational audits, businesses need to clearly identify the departments, areas, and activities that require evaluation. Defining the scope of application helps focus audit resources on critical, high-risk areas or those with a significant impact on operational efficiency and management.
| Object | Description of Contents Key Reviews | Objectives of Operational Audit |
| Production/Operations Department | Assess resource utilization efficiency (raw materials, machinery, energy), optimize production processes, and improve labor productivity. | Eliminate waste, increase production efficiency, and reduce product costs. |
| Sales/Marketing Department | Evaluate the effectiveness of the sales strategy (achieving revenue and market share targets) and the return on investment (ROI) of marketing/sales costs. | Increase business efficiency and optimize customer acquisition costs. |
| Finance/Accounting Department | Review the economic efficiency of capital management, budget expenditures, debt management, and the effectiveness of the financial management information system. | Ensure optimal use of capital, improve cost management and cash flow. |
| Human Resources (HR) Department | Evaluate the effectiveness of recruitment, training, and development processes. Ensure the effectiveness of talent retention and compensation policies. | Optimize personnel costs relative to productivity, reducing employee turnover rate. |
| IT & Technology Department | Assess the economic viability of technology investments, the operational efficiency of systems, and the effectiveness of data security measures. | Ensure that IT investments deliver tangible value, improving system availability and security. |
| High-Risk Activities | Focus on areas prone to errors, corruption, waste, or activities that have a significant financial impact on the business. | Ensure audit resources are allocated optimally, focusing on areas that need the most improvement. |
Methods and techniques of performance auditing
To ensure that an operational audit (RO) not only detects errors but also delivers real improvement value, auditors need to apply a flexible combination of quantitative and qualitative methods. These techniques are designed to thoroughly assess the economy (optimal resource utilization), efficiency (output versus input), and effectiveness (achieving objectives) of the business's operations.
The table below summarizes common and advanced methods, their specific purposes, and how to apply them in practice:
| No. | Method / Technique | Main purpose | Application methods and illustrative examples |
| 1 | Quantitative Audit | Evaluate economic efficiency and effectiveness based on numerical data and the relationship between inputs and outputs. | Utilize trend analysis, horizontal/vertical comparisons, and ratio analysis (e.g., Cost/Unit, Profit Margin/Investment). |
| 2 | KPI and Performance Indicator Analysis | Determine the difference between actual results and set targets (effectiveness). | Compare actual results with plans, industry standards, or best practices (benchmarking). Identify underperforming activities. |
| 3 | Qualitative Audit | Evaluate non-measurable factors (process effectiveness and efficiency). | Analyze the completeness and clarity of processes, assess the culture of compliance, and evaluate the quality of management decisions. |
| 4 | Root Cause Analysis (RCA) | Identify the root causes of the inefficiencies or wastefulness that have been discovered. | Use techniques such as the 5 Whys or the Fishbone Diagram (Ishikawa) to trace the error back to its source. |
| 5 | Interviews, Surveys, and Focus Groups | Gather information, assess perceptions, identify barriers, and propose improvements from implementers and managers. | Conduct in-depth interviews with key personnel about processes and risks. Conduct large-scale surveys to measure satisfaction levels or administrative burdens. |
| 6 | Practical Testing (Walkthrough/Observation) | Conduct a direct assessment of the process and work environment to check the alignment between the documented process and reality (operational efficiency). | Directly observe the production/operation line, follow a transaction from start to finish to verify the steps. |
| 7 | Advanced Data Analytics (CAATs) | Handling large volumes of data, detecting anomalies, exceptions, and complex relationships in operations. | Use specialized software for statistical analysis, modeling (e.g., predicting operating costs), and examining whole datasets instead of sampling. |
| 8 | Goal Congruence Performance Evaluation | Determine the extent to which the department's goals and activities align with the overall business strategy. | Review the target-setting and reward mechanisms to ensure that departments do not act for narrow self-interest, thereby harming overall performance. |
Operational audit process
To conduct an effective operational audit, businesses need to follow a standard process that ensures a comprehensive, objective assessment and provides accurate data for process improvement. This process typically consists of five main steps:
Planning for operational audits
At this stage, auditors identify the objectives, scope, and key areas to be evaluated. Planning helps focus resources on activities that are critical, high-risk, or have a significant impact on business performance. Simultaneously, the plan defines the data collection methods, timeline, and audit team.
Gathering and analyzing operational audit information.
Auditors collect data from relevant departments, including reports, records, operating procedures, and qualitative information from personnel. Operational audits use this data to assess efficiency, compliance with procedures, and identify potential risks.
Conduct a performance audit.
This step involves direct observation, process inspection, employee interviews, and comparison of actual results with internal standards, KPIs, or regulations. Operational audits at this stage help identify strengths, weaknesses, and anomalies in operations.
Prepare an operational audit report and provide recommendations.
After completing the audit, the auditor compiles the results into a detailed report, outlining the level of effectiveness, risks, and areas for improvement. Simultaneously, the operational audit proposes specific recommendations to optimize processes, reduce costs, and enhance operational efficiency.
Follow-up and monitoring after performance audits.
Monitoring the implementation of recommendations and evaluating the results of improvements helps ensure that operational audits remain effective in the long term and prevent similar risks in the future.
Benefits of performance audit
Operational auditing is not just a routine review but a strategic tool that helps businesses comprehensively and objectively review their entire operational process. Through this, businesses can identify weaknesses, leverage strengths, and make timely adjustments to achieve sustainable growth. Below are five of the most prominent benefits that operational auditing brings to businesses:
Improve operational efficiency
Operational audits help businesses assess the level of resource utilization, such as human resources, finances, and assets. From this, businesses can identify inefficiencies, adjust processes to reduce waste, and increase productivity and overall efficiency.
Identify and address weaknesses in management.
Through an independent assessment process, auditors identify errors or weaknesses in the internal control system. This provides businesses with a basis to improve their organizational structure, enhance operational capabilities, and prevent risks.
Enhancing transparency and accountability
Operational audits help ensure that all processes, activities, and reports are transparent and compliant with regulations. This makes it easier for businesses to explain their operations to shareholders, regulators, and partners, increasing their credibility and trust in the market.
Supporting strategic decision-making
Audit results provide factual and objective data that helps management assess operational performance. This allows businesses to make more accurate strategic decisions, optimize resources, and guide long-term development.
Minimize risks and optimize costs.
Operational audits help detect risks in operational processes early, preventing unnecessary losses. Simultaneously, cost-benefit analysis helps businesses eliminate inefficient activities, saving costs while maintaining quality.
The risks of not conducting operational audits.
Failing to conduct regular operational audits can cause businesses to miss many opportunities to improve efficiency and create a range of risks in management and operations. Operational audits not only help identify problems but also provide a foundation for accurate decision-making. Below are typical risks if a business does not conduct operational audits:
| No. | Risk | Detailed description |
| 1 | Low resource utilization efficiency | Without independent evaluation, businesses struggle to identify areas of waste in the use of personnel, assets, and expenses. This leads to low efficiency and increased operating costs. |
| 2 | Lack of internal controls and weak risk management. | Without operational audits, businesses fail to detect errors, fraud, or potential risks in their processes in a timely manner. Internal control systems gradually become less effective. |
| 3 | Making flawed decisions due to a lack of reliable data. | A lack of auditing means that businesses do not have an objective database of operational efficiency. Strategic decisions may therefore be based on inaccurate information, leading to serious consequences. |
| 4 | Loss of credibility and transparency with investors and partners. | The lack of audit reports leaves businesses without a basis to demonstrate their governance capabilities and transparency. This reduces the trust of shareholders, partners, and regulatory authorities. |
| 5 | Achieving sustainable development is difficult. | When internal problems are not detected and addressed promptly, businesses are prone to operational imbalances, reduced competitiveness, and difficulty sustaining long-term growth. |
Criteria for selecting a reputable performance auditing firm.
Choosing a reputable performance audit firm is crucial to ensuring your business receives accurate, objective, and useful results for improving management efficiency. Below are some important criteria to consider:
Expertise and experience in performance auditing.
A reputable auditing firm needs a team of experienced auditors with in-depth knowledge of the industry and the business's operational processes. This allows them to quickly identify risks, errors, and weaknesses in operations, thereby helping the business improve its management and operational efficiency.
Practical experience also helps the auditing firm make specific and feasible recommendations, helping businesses optimize processes, enhance competitiveness, and translate audit results into practical solutions.
Reputation and credibility in performance auditing.
The reputation of an operational audit firm is assessed through its brand, past clients, certifications, and actual feedback. A reputable firm will have a transparent operational audit methodology, adhere to international standards, and ensure that the audit process is closely monitored.
Reputable firms also provide transparent information about service costs, tailored to the scale and scope of work, helping businesses accurately budget. The combination of reputation, expertise, and professional operational auditing methods ensures accurate audit results, increasing practical value and improving management efficiency.
Clear and transparent audit methodology in performance auditing.
The auditing firm needs to apply standardized, transparent methods and adhere to international standards. A clear audit process helps businesses track progress, evaluate results, and trust the recommendations made, ensuring that all information is assessed objectively and accurately.
Consulting and support for improvement in performance auditing.
In addition to conducting audits, the unit also provides recommendations for improvement and advises on solutions to optimize operations. This helps businesses translate audit results into practical actions, improve operational efficiency, and minimize management risks.
Reasonable and transparent costs in performance audits.
Service costs should be appropriate to the size, industry, and scope of work of the business. Transparency in pricing and agreements helps businesses accurately budget and avoid unexpected costs, while ensuring the effectiveness of the investment in the auditing process.
