Audit Phases CISA Exam Notes, 36 Practice Questions

The IS audit process is a structured approach used by an IS auditor to plan, execute, report, and follow up on an audit engagement. For CISA, audit phases are important because many questions test what the auditor should do FIRST, BEST, NEXT, or MOST appropriately at each stage.

The standard exam-friendly sequence is: Planning → Fieldwork / Documentation → Reporting → Follow-up

Some materials mention Documentation separately, but practically it happens throughout the audit, especially during fieldwork and reporting.



Audit Phases Overview

PhaseMain PurposeFocus
PlanningDefine what, why, how, and where to auditRisk assessment, scope, objectives, audit program
FieldworkPerform audit procedures and collect evidenceTesting controls, gathering evidence, validating findings
DocumentationRecord procedures, evidence, findings, and conclusionsWork papers must support audit conclusions
ReportingCommunicate results to management and stakeholdersDiscuss findings, management response, final report
Follow-upVerify corrective actionConfirm remediation and operating effectiveness

Phase 1: Planning

The planning phase determines the direction of the audit. It defines the audit objective, scope, methodology, resources, and areas of focus.

Key Activities:

  • Define the audit objective
  • Define the audit scope
  • Understand the business process or system being audited
  • Identify applicable:
    • Policies
    • Standards
    • Procedures
    • Laws and regulations
  • Review previous audit reports and prior findings
  • Perform a risk assessment
  • Identify high-risk areas
  • Prepare the audit plan
  • Develop the audit program
  • Allocate audit resources
  • Establish communication with stakeholders

Exam Tip: The most critical planning activity is usually: Performing a risk assessment. Why? Because risk assessment helps determine where audit effort should be focused.

If resources are limited, the auditor should: Focus on high-risk areas. Do not choose options like auditing all areas equally or simply following management preference.

Audit Plan vs Audit Program

TermMeaning
Audit PlanHigh-level plan showing audit objective, scope, timing, resources, and approach
Audit ProgramDetailed step-by-step audit procedures to execute the audit

Phase 2: Fieldwork

The fieldwork phase is where the auditor performs audit procedures, tests controls, gathers evidence, and validates whether controls are designed and operating effectively.

Key Activities

  • Conduct interviews
  • Observe processes
  • Inspect documents and records
  • Review configurations and logs
  • Perform control testing
  • Perform compliance testing
  • Perform substantive testing
  • Use CAATs or data analytics where appropriate
  • Identify potential findings
  • Gather sufficient and appropriate evidence
  • Validate issues before reporting

Exam tip:

If an auditor identifies a potential control weakness, the first action should be: Gather additional evidence to validate the finding. Do not report immediately without evidence.

Compliance Testing vs Substantive Testing

Testing TypePurpose
Compliance testingDetermines whether controls, policies, or procedures are being followed
Substantive testingTests transactions, data, or balances in detail to verify accuracy/completeness

Evidence Quality

Audit evidence should be:

  • Sufficient — enough evidence
  • Appropriate — relevant and reliable
    • Reliable — dependable source
    • Relevant — directly related to the audit objective

Evidence Reliability Ranking

Generally:

  • Auditor-obtained evidence > Management-provided evidence
  • External evidence > Internal evidence
  • Written evidence > Oral evidence

Design vs Operating Effectiveness

ConceptBest Audit Technique
Design effectivenessWalkthrough
Operating effectivenessReperformance/testing

Exam Tip:

If the question says potential finding, suspected issue, or possible weakness, the best answer is usually: Perform additional testing / gather more evidence


Phase 3: Documentation

Audit documentation records the work performed and supports the auditor’s findings, conclusions, and recommendations.

Key Contents

  • Audit objective and scope
  • Audit program
  • Procedures performed
  • Evidence obtained
  • Test results
  • Findings
  • Conclusions
  • Recommendations
  • Management responses
  • Follow-up actions
  • Use of experts, if applicable

Exam tip:

  • The primary purpose of audit documentation is: To support audit procedures, findings, and conclusions.
  • Audit work papers are important because they provide a link between: Audit objectives → Audit procedures → Evidence → Findings → Final report
  • Audit documentation does not replace testing. It supports the audit work already performed.

Phase 4: Reporting

The reporting phase communicates audit results to management and relevant stakeholders.

Key Activities

  • Draft audit report
  • Validate findings
  • Discuss findings with auditee management
  • Confirm factual accuracy
  • Obtain management responses
  • Include recommendations
  • Issue final audit report
  • Communicate risk and business impact

Final Audit Report Usually Includes

  • Audit objective
  • Scope
  • Summary of work performed
  • Findings
  • Risk/impact
  • Recommendations
  • Management responses/action plans
  • Target remediation dates, if applicable

Exam tips:

Before issuing the final report, the auditor should: Discuss findings with auditee management. This helps confirm factual accuracy and obtain management responses.

If management disagrees with a finding or impact rating, the auditor should: Explain the significance, risk, and effect of not correcting the weakness

If disagreement remains, the auditor may document management’s disagreement in the final report.

If management corrects a weakness during the audit, the auditor should: Include the finding in the report and mention the corrective action taken

Do not exclude the finding just because it was corrected before the final report.

Reporting should not happen until the finding is supported by sufficient and appropriate evidence.


Phase 5: Follow-up

The follow-up phase determines whether management has implemented corrective actions and whether those actions effectively address the risk.

Key Activities

  • Track agreed corrective actions
  • Verify implementation
  • Test whether the new or changed control is operating effectively
  • Assess residual risk
  • Report unresolved issues
  • Escalate overdue or ineffective remediation when appropriate

Exam tips:

The follow-up phase is primarily performed to determine whether: Management implemented corrective actions

Do not accept management’s statement alone.

A control existing on paper does not mean it is operating effectively.

The auditor should go one step deeper and verify not only implementation, but also effectiveness.

If management states that an issue has been fixed, the auditor should: Verify implementation through testing or review.

If management implemented the recommended control but it is not operating effectively, the auditor should: Report that remediation is incomplete or ineffective,


Exam Mindset

For Audit Phases questions, CISA is not just testing memory. It is testing professional audit judgment.

Always ask yourself:

  1. Is this still planning, testing, reporting, or follow-up?
  2. Does the auditor have enough evidence?
  3. Has management been given a chance to respond?
  4. Has remediation actually been verified?
  5. Is the response risk-based?

Final Exam Mantra

Plan based on risk → Find evidence through testing → Document everything → Report accurately → Follow up until remediation is verified.

Risk → Evidence → Report → Remediate → Verify
