Judgment, Direction and Supervision in Audit Planning and Execution

Updated 5 October 2026 · Fact-checked

Under SA 300 and SA 220, the auditor uses professional judgment to plan and perform procedures, and the engagement partner directs, supervises and reviews the team. Planning matters are discussed with those charged with governance without compromising effectiveness. Answer by stating the provision, applying case facts, then concluding.

Understand Judgment, Direction and Supervision in Planning and Execution

An audit has no fixed script. The auditor must decide what to test, how much to test and who should do it. These decisions need professional judgment: applying relevant training, knowledge and experience, within the context of auditing and ethical standards, to reach informed decisions. Judgment is needed in planning (materiality, risk, nature, timing and extent of procedures) and in execution (is the evidence enough, is an estimate reasonable).

Judgment alone is not enough. Work is done by a team, so the partner must make sure each member knows what to do and that it is done well. This has three parts. Direction means informing team members of their responsibilities, the objectives of the work, the nature of the entity's business, risk issues, problems that may arise and the detailed approach. Supervision means tracking progress, checking that members understand and can do the work, and dealing with significant matters that arise. Review means checking that the work was done, was adequate, supports the conclusions and is properly documented.

The extent of direction and supervision depends on the size and complexity of the entity, the area being audited, the assessed risks of material misstatement, and the capabilities and competence of team members. A riskier area or a less experienced person needs closer supervision. Review is done by more experienced members on the work of less experienced ones, and the engagement partner reviews critical areas, such as significant judgments and significant risks.

Planning also involves communication with those charged with governance (TCWG). The auditor may discuss elements of planning, such as the scope and timing of the audit and significant risks, to help TCWG understand the audit and to help the auditor understand the entity. The auditor must take care: detailed procedures should not be disclosed in a way that makes them predictable and reduces audit effectiveness. The overall audit strategy and audit plan remain the auditor's responsibility.

The link to quality is direct. Good judgment, proper supervision and timely review reduce the chance of an inappropriate opinion. Documentation of the judgments, and of who reviewed what and when, is the evidence that this was done.

Key rules to remember

Professional judgment: Judgment = training + knowledge + experience, applied within auditing and ethical standards; Needed for materiality, risk assessment, evidence sufficiency and estimates. It must be exercised, not assumed, and be documented where significant.
Direction of the team: Direction = responsibilities + objectives + nature of business + risks + problems + detailed approach; Given to team members at the start of the engagement. Use this as a checklist in written answers.
Supervision: Supervision = track progress + check understanding and competence + resolve significant matters + guide team; Extent depends on size, complexity, assessed risk and team capability.
Review: Review = work performed + adequate + supports conclusions + documented; Done by more experienced members on less experienced members' work. The partner reviews critical areas and significant judgments.
Communication with TCWG on planning: Discuss scope, timing and significant risks; do not compromise effectiveness; responsibility for strategy and plan stays with the auditor; Detailed procedures should not be shared in a way that makes the audit predictable.

How to solve Judgment, Direction and Supervision in Planning and Execution questions

Use this method for any question on judgment, team direction, supervision, review or planning communication.

1Read the case and identify which element is tested: judgment, direction, supervision, review or communication with TCWG.
2State the relevant provision in plain words (SA 300, SA 220 or the SQC principle) in one or two lines.
3List the case facts that matter: entity complexity, risk level, team experience, timing, and what was or was not done.
4Apply the provision to each fact. Say what the standard expects and where the auditor met or missed it.
5Check who is responsible. The engagement partner is responsible for direction, supervision and review; the auditor, not TCWG, owns the strategy and plan.
6Write a clear conclusion and, if needed, the corrective action such as closer supervision, partner review of the area, or documenting the judgment.
7Mention documentation where relevant, since judgments and reviews must be evidenced.

Quickest way: Provision, facts, conclusion in three lines

When to use it: Use when time is short, especially in case-scenario MCQs and 4 to 5 mark written answers.

Name the element tested: judgment, direction, supervision, review or TCWG communication.
Match the key trigger in the case: high risk or junior staff means closer supervision; predictable procedures means do not disclose detail; uncertainty means exercise and document judgment.
Pick the option or write the conclusion that keeps responsibility with the auditor and the partner.
In MCQs, reject options that hand planning decisions to management or TCWG, or that say review is optional for junior work.

Common mistakes in Judgment, Direction and Supervision in Planning and Execution

Treating direction, supervision and review as the same thing.
They happen together on the engagement and sound similar.
Fix: Remember the order: direction tells people what to do, supervision watches while they do it, review checks it after it is done.
Saying the auditor must share the full audit plan with TCWG.
Students over-apply the idea of communication.
Fix: Say that planning matters may be discussed, but detailed procedures should not be revealed in a way that makes the audit predictable. The plan stays the auditor's responsibility.
Applying the same level of supervision to every area.
Students forget that supervision is risk-based.
Fix: Link the extent to the entity's size and complexity, the assessed risks and the competence of the team members.
Leaving professional judgment undefined or unsupported in the answer.
Students write 'the auditor will use judgment' and stop.
Fix: Say where judgment applies, what factors it rests on, and that significant judgments are documented.
Assuming the engagement partner can delegate responsibility for review of critical areas.
Students confuse delegating tasks with delegating responsibility.
Fix: State that tasks may be delegated, but the partner remains responsible and reviews significant judgments and critical areas.

Worked examples

Example 1

Case: In the audit of a listed manufacturing company, the engagement partner assigned the audit of related party transactions, a significant risk area, to a newly joined article assistant. The partner gave no briefing and did not review the work, relying on the manager to 'look at it if time permits'. Evaluate the engagement partner's conduct.

Show the solution

Provision: the partner must ensure the team is directed, supervised and reviewed. Extent depends on assessed risk and team competence.
Facts: related party transactions are a significant risk area. The assignee is inexperienced. There was no briefing and no planned review.
Application: higher risk and lower experience call for closer direction and supervision. The partner gave neither. Review by a more experienced member was left to chance.
Responsibility: the partner may delegate tasks but remains responsible, and should review significant judgments and critical areas.

Answer: The conduct is not in line with the requirements. The partner should brief the assistant on objectives, risks and approach, assign a competent senior to supervise, and personally review the work and conclusions on related party transactions, with the review documented.

Example 2

Case: Before the audit of Rohan Ltd, the auditor met the audit committee. The chairperson asked for the full list of tests, sample sizes and dates of surprise checks so that management could prepare. Should the auditor agree? What may the auditor discuss?

Show the solution

Provision: the auditor may discuss planning matters with TCWG, such as scope, timing and significant risks.
Limit: communication must not compromise the effectiveness of the audit. Detailed procedures, if disclosed, can make the audit predictable.
Application: sample sizes and the timing of surprise checks are detailed procedures. Sharing them lets management anticipate the work.
Responsibility: the overall audit strategy and audit plan remain the auditor's responsibility, even after discussion.

Answer: The auditor should not share the detailed tests, sample sizes or surprise-check dates. The auditor may discuss the scope and timing of the audit, significant risks and areas where TCWG have concerns, while keeping control of the strategy and plan.

Exam tips

Write in provision, facts, conclusion form. Examiners reward the link between the case facts and the standard.
In scenario questions, check risk level and team experience first. These decide the extent of supervision.
For TCWG planning communication, always include both the permitted discussion and the limit on predictability.
Use the checklist for direction (responsibilities, objectives, business, risks, problems, approach) to pick up easy marks.
Keep MCQ answers consistent with the principle that responsibility stays with the auditor and the engagement partner.

Practice questions from Audit Planning, Strategy and Execution

Judgment, Direction and Supervision in Planning and Execution: frequently asked questions

What is the difference between direction, supervision and review?

Direction is informing the team of responsibilities, objectives, risks and approach. Supervision is monitoring progress and helping during the work. Review is checking the completed work to see it is adequate and supports the conclusions.

Who is responsible for direction, supervision and review of the team?

The engagement partner is responsible. Tasks can be assigned to others, but the partner stays responsible and reviews critical areas and significant judgments.

Can the auditor discuss the audit plan with those charged with governance?

Yes, the auditor may discuss elements of planning such as scope, timing and significant risks. The auditor must not reveal detailed procedures in a way that reduces the effectiveness of the audit. The strategy and plan remain the auditor's responsibility.

Why is professional judgment needed in planning?

Planning involves decisions on materiality, risk, and the nature, timing and extent of procedures, and standards cannot fix these for every entity. The auditor applies training, knowledge and experience to decide, and documents significant judgments.
