What should an IS auditor do first when using data analytics for an audit?

CISA By islever Editorial Last updated Sep 9, 2026

Short answer

B Define data needs to align the analytics scope with established audit objectives before sourcing or processing information.

Question

When using data analytics to perform an audit, the IS auditor should FIRST:

identify testing models
define data needs Correct Answer
identify data sources
prepare the data

Key Takeaways

The exam tests logical audit workflow sequencing, where candidates often confuse gathering available data with establishing specific analytical requirements.

This question tests the initial phase of integrating data analytics into an audit engagement. It establishes that defining data needs must precede source identification or preparation to align analysis with audit objectives.

Common mistake: Candidates frequently choose identify data sources first, mistakenly prioritizing data availability over audit objective alignment.

Expert Analysis

Why the Answer Is Correct

Defining data needs is the mandatory first step because it directly ties the analytics initiative to the audit plan and risk assessment. ISACA methodology mandates that auditors establish clear objectives and specify required datasets before any technical execution begins. This foundational step ensures that subsequent sourcing, modeling, and preparation activities remain focused and efficient.

Why the Other Options Are Wrong

Identifying testing models requires prior knowledge of both audit objectives and available data structures, making it a downstream activity. Pinpointing data sources prematurely ignores whether those sources actually contain the metrics necessary to satisfy audit goals. Preparing the data is strictly an execution-phase task that occurs only after requirements are locked and sources are verified.

Community Comment Notes

Most learners emphasize that establishing clear requirements creates the roadmap for the entire engagement, ensuring relevant insights emerge from the analysis. A minority argues that locating available repositories should come first, but this overlooks how unguided data collection wastes time and introduces compliance risks. As KAP2HURUF observed, defining needs "sets the foundation for the subsequent steps" in the process.

Exam Strategy

Always anchor your data analytics steps to the audit plan and objectives first. Sequence tasks by business need, not technical convenience, to avoid scope creep and wasted effort.

Frequently Asked Questions

Why isn't identifying data sources the first step?

Source identification depends on knowing exactly what data supports the audit objectives, which requires defining needs first.

How does defining data needs impact testing models?

Clear data requirements dictate which analytical techniques and models are appropriate, preventing mismatched testing approaches.

KAP2HURUF 👍 2 Answered B

When using data analytics to perform an audit, the IS auditor should first define the data needs. This involves understanding the audit objectives and determining what data is required to meet those objectives. Defining the data needs sets the foundation for the subsequent steps in the data analytics process, as it guides the auditor in identifying which data to collect and how to analyze it.

Once data sources have been identified, the auditor can then proceed with defining testing models (Option A) based on the audit objectives and the nature of the data available. Therefore, identifying data sources (Option C) is the FIRST step in the data analytics process when performing an audit.

By defining data needs first, the IS auditor establishes a clear direction for the entire data analytics process, ensuring they gather the right information, use appropriate techniques, and ultimately derive valuable audit insights.
