Audit Strategy and Audit Plan under ISA 300 for ACCA AA

Updated 11 October 2026 · Fact-checked

Under ISA 300, the overall audit strategy sets the scope, timing and direction of the audit. The audit plan is more detailed: it lists the risk assessment procedures and the further audit procedures to perform. Planning is not a one-off step. You update both as new information arises during the audit.

Understand Audit Strategy and Audit Plan

Planning means deciding how the audit will be done before you start the detailed work. ISA 300 requires the auditor to plan so that the audit is performed in an effective manner. Good planning helps you give attention to important areas, find problems early, use the team well and manage cost and time.

The overall audit strategy is the big picture. It sets the scope, timing and direction of the audit and guides the detailed plan. It covers the characteristics of the engagement, such as the financial reporting framework, industry reporting needs and the locations in scope. It covers reporting objectives, timing and communications, such as deadlines and expected meetings. It also covers significant factors that direct the team, such as materiality, high-risk areas, and the nature, timing and extent of resources needed.

The audit plan is more detailed. It sets out the nature, timing and extent of risk assessment procedures. It sets out the nature, timing and extent of further audit procedures at assertion level. It also lists any other procedures needed to meet ISA requirements. Think of the strategy as the map and the plan as the step-by-step route.

Planning is iterative. You plan, start work, and learn new facts. A control may fail testing, a fraud indicator may appear, or the client may change its business. You then revise the strategy and plan, and you may change the procedures or extend them. Document the changes and the reasons.

For continuing audits, you use prior-year knowledge, but you must still consider what has changed. The engagement partner and key team members should be involved in planning. The team should discuss the susceptibility of the financial statements to material misstatement. Planning is also not a single phase. It is continuous through the audit.

Key rules to remember

Strategy vs plan: Strategy = scope, timing, direction. Plan = detailed procedures (risk assessment + further audit procedures).; Strategy comes first and guides the plan. The plan is more detailed.
Planning is iterative: Plan → perform → learn → revise strategy and plan → document; ISA 300 requires you to update the strategy and plan as necessary during the audit.
Procedures described in the plan: Nature, timing, extent; Use these three words to structure answers on what the plan contains.
Benefits of planning: Focus on key areas, spot issues early, organise work, direct and review team, coordinate experts and others; Use these as a checklist for why planning is important.

How to solve Audit Strategy and Audit Plan questions

Use this method for any question on planning, whether it asks for definitions, contents or the reasons for planning.

1Read the requirement and note the verb: explain, describe, list, or distinguish. This tells you the depth needed.
2Decide whether the question is about the strategy, the plan, or both. Keep them separate.
3For contents, use headings: scope and engagement characteristics, timing and reporting, direction (materiality, risks, resources), then detailed procedures.
4If a scenario is given, link each point to a fact in it, such as a new system, a new location or a high-risk area.
5For the benefits of planning, state the benefit and add why it matters to the audit.
6Mention that planning is iterative and give a scenario-based reason for revision if one appears.
7Keep points short, with one point per sentence or bullet, so each can earn a mark.
8Check the number of marks and make sure you have made about as many distinct points.

Quickest way: Strategy, plan, update

When to use it: Use it for short objective questions and for written parts worth a few marks, when time is tight.

Ask: is this about the big picture (strategy) or the detailed procedures (plan)?
Scope, timing, direction means strategy. Nature, timing, extent of procedures means plan.
If the question mentions new facts found mid-audit, the answer is to revise the strategy and plan.
Write one clear point per mark and tie it to the scenario.

Common mistakes in Audit Strategy and Audit Plan

Using strategy and plan as if they mean the same thing.
Both are planning documents and the names sound similar.
Fix: Remember that the strategy sets scope, timing and direction, while the plan lists detailed procedures.
Saying planning is a stage that finishes before fieldwork.
Textbooks show planning first in a sequence.
Fix: State that planning is continuous and iterative, and the strategy and plan are updated as needed.
Listing generic benefits of planning with no link to the scenario.
Students recite memorised lists.
Fix: Tie each benefit to a scenario fact, such as a new accounting system needing early IT specialist involvement.
Writing audit procedures when asked for planning contents.
Students jump to what they would test.
Fix: Read the requirement. Contents of the strategy are scope, timing, risks and resources. Only the plan lists procedures.
Forgetting to say that changes must be documented.
Students focus on the revising and not on the record.
Fix: Add that the strategy, plan and any significant changes, with reasons, must be documented.

Worked examples

Example 1

Explain the difference between the overall audit strategy and the audit plan, and explain why planning is iterative. (6 marks)

Show the solution

Define the strategy: it sets the scope, timing and direction of the audit and guides the development of the plan.
Give examples of strategy content: the financial reporting framework, reporting deadlines, key risk areas, materiality and the resources needed.
Define the plan: it is more detailed and sets out the nature, timing and extent of risk assessment procedures and further audit procedures.
Explain the link: the plan is built within the strategy.
Explain iteration: during the audit, new information may arise, such as control failures, fraud indicators or changes in the client's operations.
Conclude that the auditor must then update the strategy and plan, change the procedures if needed, and document the changes.

Answer: The overall audit strategy sets the scope, timing and direction of the audit, covering matters such as the reporting framework, deadlines, key risks, materiality and resources. The audit plan is more detailed and lists the nature, timing and extent of procedures. Planning is iterative because new information found during the audit may change the risks. The auditor then revises the strategy and plan and documents the changes.

Example 2

You are planning the audit of a manufacturing client that has just installed a new inventory system and opened a second warehouse. Explain why planning is important for this audit. (5 marks)

Show the solution

Point 1: early planning helps you focus on key areas. The new inventory system and the new warehouse are likely risk areas.
Point 2: it helps identify problems early, such as data migration errors in the new system, so there is time to respond.
Point 3: it helps organise resources. You may need an IT specialist and staff to attend inventory counts at two sites.
Point 4: it helps direct and supervise the team. Staff need briefing on the new risks.
Point 5: it helps make sure the work is done on time and at reasonable cost, which keeps the audit within the client's reporting deadline.

Answer: Planning is important because it focuses attention on the new inventory system and second warehouse, identifies problems such as migration errors early, and organises resources such as an IT specialist and count attendance at both sites. It also lets the team be briefed and supervised properly, and helps the audit finish on time and at reasonable cost.

Exam tips

Always separate the strategy (scope, timing, direction) from the plan (detailed procedures). A mix-up loses easy marks.
Use the scenario. Mark schemes reward points linked to the facts given, not a general list.
Mention that planning is iterative and that changes are documented. It is a common extra mark.
For a short objective question, find the key word: scope, timing and direction mean strategy; nature, timing and extent mean plan.
Match the number of points to the marks available, and keep each point short.

Audit Strategy and Audit Plan: frequently asked questions

What is the difference between an audit strategy and an audit plan?

The overall audit strategy sets the scope, timing and direction of the audit. The audit plan is more detailed and lists the procedures to be performed. The plan is developed within the strategy.

Why is audit planning important in ACCA AA?

Planning helps the team focus on important areas, find problems early and organise the work. It also supports team direction and review, and helps the audit finish on time at a reasonable cost.

What is an audit planning memorandum?

It is a document that records the planning decisions for an audit. It typically covers the client and its business, key risks, materiality, the approach to the audit, resources and timing. The exact layout varies between firms.

Why is planning an iterative process?

New information can arise during the audit, such as a failed control or a change in the client's business. You must then revise the strategy and plan and document the changes.
