1. Introduction to the TechniqueJudgmental sampling, also known as non-statistical or purposive sampling, is a method where the internal auditor selects items for testing based on professional judgment, experience, and risk assessment, rather than random or systematic selection. It is especially useful when the auditor wants to focus on transactions that are more likely to […]
1. Introduction to the TechniqueStratified sampling is an internal audit technique where the population is divided into subgroups—or strata—based on characteristics such as value, risk, or type of transaction. Samples are then drawn from each subgroup, ensuring better representation and focus on higher-risk areas. This approach is more efficient than random sampling when some categories […]
1. Introduction to the TechniqueRandom sampling is a statistical tool used by internal auditors to select a subset of transactions or data from a larger population for testing. The goal is to provide reasonable assurance about the entire population by evaluating just a portion of it. This technique is especially helpful when auditing high-volume processes […]
1. Introduction to the TechniqueProcess mapping (or flowcharting) is a visual audit tool used to document and understand how a business process flows from start to finish. It highlights the steps involved, the people responsible, decision points, and documents or systems used. Internal auditors like Auren at ACME Corp use process maps to identify control […]
1. Introduction to the TechniqueDocument review is one of the foundational techniques in internal audit. It involves examining policies, procedures, reports, contracts, records, logs, and other formal documentation to validate that processes are designed and operating as intended. For internal auditor Auren at ACME Corp, reviewing documents helps build a fact-based understanding of control design, […]
1. Introduction to the TechniqueObservation is a valuable audit technique that involves watching a process or control being performed in real time. It allows auditors to see what actually happens—not just what is written in procedures. For internal auditor Auren at ACME Corp, observation provides an unfiltered view of operations and control behavior, helping identify […]
1. Introduction to the TechniqueSurveys and questionnaires are efficient internal audit tools for gathering structured information from a wide audience. They help auditors like Auren at ACME Corp collect standardized responses on perceptions, practices, or compliance across departments, often within a short time frame. These tools are especially useful during the planning or fieldwork stages […]
1. Introduction to the TechniqueInterviews are one of the most practical and widely used techniques for gathering audit evidence during fieldwork. They allow internal auditors to gain deeper insights into how processes operate, understand control effectiveness, and validate documentation through direct conversations with employees. For Auren, the internal auditor at ACME Corp, interviews are more […]
1. Introduction to the TechniqueA walkthrough is a foundational technique in internal audit fieldwork used to understand how a process works from start to finish. It involves tracing a transaction or process step-by-step, usually by observing and asking questions of process owners. Walkthroughs help internal auditors like Auren verify that documented procedures are followed in […]
1. Introduction to the TechniqueScenario Analysis is a forward-looking tool used by internal auditors and risk managers to evaluate how different hypothetical events or situations could impact business objectives. Instead of focusing only on known risks, this technique challenges teams to think about “what if” situations—especially useful for strategic planning, crisis preparedness, or assessing emerging […]
