Audit Planning and Audit Strategy under SA 300

Updated 10 October 2026 · Fact-checked

Audit planning means the auditor decides how to conduct the audit so that it is performed in an effective manner. Under SA 300, you set an overall audit strategy (scope, timing, direction) and then a detailed audit plan (nature, timing and extent of procedures). Write both, link them, and update them as the audit proceeds.

Understand Audit Planning and Audit Strategy

Audit planning is the work the auditor does before and during the audit to make sure the right areas get the right attention at the right time. It is governed by SA 300, Planning an Audit of Financial Statements. Planning is not a one-time step at the start. It is a continual and iterative process that runs through the whole audit.

The auditor first prepares an overall audit strategy. It sets the scope, timing and direction of the audit and guides the detailed plan. Then the auditor prepares an audit plan, which spells out the nature, timing and extent of the risk assessment procedures and of the further audit procedures, plus any other procedures needed to comply with the SAs.

Think of the strategy as the map of the whole journey and the plan as the turn-by-turn directions. The strategy answers: what are we auditing, when, and with whom? The plan answers: which exact procedures, on which items, by whom, and in what quantity?

Good planning helps the auditor pay appropriate attention to important areas, identify and resolve potential problems on time, organise and manage the audit well, select team members with suitable capabilities, direct and supervise them, review their work, and coordinate with component auditors and experts. For a continuing engagement, the auditor also considers experience from earlier years.

The engagement partner and other key members of the engagement team should be involved in planning, including in the discussion among team members about the risks of material misstatement. The auditor may also discuss elements of planning with the entity's management, but the auditor remains responsible for the strategy and plan.

Key rules to remember

Overall audit strategy: Scope + Timing + Direction of the audit; Sets the characteristics of the engagement, reporting objectives and the nature of resources needed. It guides the detailed plan.
Audit plan: Nature + Timing + Extent of procedures; Covers risk assessment procedures, further audit procedures, and other procedures needed to comply with the SAs.
Order of work: Strategy first, then plan; both updated as needed; Planning is continual and iterative. Changes in conditions or unexpected evidence may need changes to both.
Preliminary engagement activities: Continuance of client relationship + Ethical requirements incl. independence + Engagement terms understood; These are done at the start of the current audit, as required by SA 220 and SA 210, before the strategy is set.
Documentation under SA 300: Document the overall audit strategy, the audit plan, and any significant changes made during the audit with the reasons; Documentation is part of the audit file, not optional.

How to solve Audit Planning and Audit Strategy questions

Use this method for any question on audit planning, whether it asks for a definition, a difference, a list of benefits or a case-based answer.

1Identify what is asked: meaning, strategy vs plan, benefits, planning activities, or a case scenario.
2Start with the SA 300 anchor: planning is a continual and iterative process, not a one-off step.
3If it is a scenario, pull out the facts: size of entity, new or continuing client, industry risks, IT systems, locations, team strength.
4Link each fact to a planning decision: scope, timing, direction, team composition, use of experts or component auditors, extent of procedures.
5Separate strategy points (broad) from plan points (detailed procedures) in your answer.
6Mention engagement team involvement, supervision, direction and review where relevant.
7Close with documentation and the need to revise the strategy and plan if circumstances change.

Quickest way: S-T-D then N-T-E

When to use it: Use this for difference questions, short notes and 2-mark style objective questions where time is tight.

Strategy = S-T-D: Scope, Timing, Direction. Think broad and early.
Plan = N-T-E: Nature, Timing, Extent. Think procedures and detail.
Strategy comes first and guides the plan; the plan is more detailed.
Both are iterative: update them when conditions change.
In a MCQ, if an option says planning is done only once at the start, reject it.

Common mistakes in Audit Planning and Audit Strategy

Treating planning as a one-time activity done only before fieldwork.
Students link the word planning with the beginning of the audit.
Fix: Write that SA 300 calls planning a continual and iterative process that continues through the audit, with changes documented.
Mixing up the strategy and the plan, or giving the same points for both.
Both documents sound alike and both guide the audit.
Fix: Use S-T-D for strategy and N-T-E for plan. Say the strategy guides the plan and the plan is more detailed.
Forgetting preliminary engagement activities such as independence and continuance of the client.
Students jump straight to the audit programme.
Fix: Begin the planning list with client continuance, ethical and independence checks, and understanding of engagement terms.
Leaving out the engagement team's role.
Planning is seen as the auditor's solo task.
Fix: State that the engagement partner and key team members take part in planning and in the team discussion on risks of material misstatement.
Writing generic benefits with no link to the case given.
Students memorise a list and copy it.
Fix: Tie each benefit to the facts, for example a new client needing more time for understanding the business, or multiple locations needing component auditor coordination.

Worked examples

Example 1

Distinguish between the overall audit strategy and the audit plan under SA 300. (14 marks style, short answer)

Show the solution

Define the strategy: it sets the scope, timing and direction of the audit and guides the development of the audit plan.
Define the plan: it is more detailed and sets out the nature, timing and extent of planned risk assessment procedures and further audit procedures, plus other procedures needed to comply with the SAs.
Contrast on content: strategy covers characteristics of the engagement, reporting objectives, timing and communications, significant factors and resources; the plan covers specific procedures and their quantity.
Contrast on sequence: strategy is prepared first, then the plan follows from it.
Note the link: the two are closely interrelated and not separate discrete processes, and changes in one may need changes in the other.
Add that both are updated as the audit proceeds and documented.

Answer: The overall audit strategy is the broad, early document fixing scope, timing and direction. The audit plan is the detailed document fixing the nature, timing and extent of procedures. The strategy guides the plan, both are revised as needed, and both are documented.

Example 2

Mehta & Co., a firm of chartered accountants, is appointed first-time auditor of Sunrise Textiles Ltd, which has three factories in different states and a newly installed ERP system. List the planning matters the auditor should address.

Show the solution

Preliminary activities: assess whether to accept the engagement, check independence and ethical requirements, and confirm the terms of engagement are understood.
Understand the business: textile industry risks, three locations, and the new ERP system. A new ERP raises risks around data migration and controls.
Strategy, scope: decide the factories to be visited and whether component auditors or local staff are needed.
Strategy, timing: schedule visits, including attendance at inventory counts, and plan interim and final audit stages.
Strategy, direction and resources: assign experienced team members to the ERP and inventory areas, consider an IT expert, and plan supervision and review.
Detailed plan: set the nature, timing and extent of risk assessment and further procedures for areas such as inventory, revenue and ERP controls.
Since this is a first-year audit, plan extra procedures on opening balances.
Hold a team discussion on risks of material misstatement with the engagement partner involved, and document the strategy, plan and later changes.

Answer: The auditor should complete preliminary engagement activities, set a strategy covering scope across three factories, timing and direction with suitable resources including an IT expert, then build a detailed plan on nature, timing and extent of procedures. First-year opening balances and ERP risks need special attention. Everything is documented and revised as needed.

Exam tips

For difference questions, give at least four points in a clear two-column style using lines such as Strategy: ... and Plan: ...
In case-based questions, quote the facts from the scenario and link each to a planning decision.
MCQs often test that planning is continual and iterative, that the strategy guides the plan, or that the engagement partner is involved. Remember these three.
When asked for benefits, give five or six short points and add one line on documentation to finish.
Do not give section numbers or figures you are unsure of. Name SA 300 and explain the idea.
