## Relationship Between Audit Strategy and Audit Plan

Though closely related, the overall audit strategy and the audit plan serve distinct purposes and operate at different levels of detail.

### Comparison

Dimension	Audit Strategy	Audit Plan
Nature	Broad overall approach	Detailed implementation roadmap
Focus	Determines scope, timing, direction	Addresses specific matters identified in the strategy
Level of detail	High-level	Includes nature, timing, and extent of each procedure
Content	What to focus on and why	How to test — specific procedures per team member

### Key Principles of Their Relationship

1. Strategy comes first conceptually — once established, the plan is developed to address the matters it identifies.

2. The plan is more detailed — it specifies procedures for each engagement team member.

3. Planning is ongoing — the audit plan is refined over the course of the audit, not locked in at the start.

4. They are not discrete or sequential — they are closely inter-related. A change in one can cause consequential changes in the other.

5. Changes in strategy affect the plan — e.g., if a new risk area is identified, the plan must be updated to include additional procedures.

6. Efficient use of resources — the plan is designed to achieve audit objectives through efficient deployment of team resources, as directed by the strategy.

> Memory cue: Strategy = MAP (sets the destination and route). Plan = ITINERARY (specifies each stop, timing, and what to do there). If you discover a road is closed (new risk), both the map and itinerary change.

Worked example

### Example 1

Strategy → Plan translation: Strategy states: 'Rely on internal controls for payroll given the company's strong HR systems and automated authorization.' Plan states: 'Test payroll controls by reviewing authorization records for a random sample of 25 transactions each in Q1, Q2, Q3, and Q4; re-assess if control deficiencies are found.' The strategy sets direction; the plan operationalizes it with specific procedures.

### Example 2

Consequential change: During fieldwork, the team discovers that the client changed its revenue recognition policy mid-year without disclosure. This is a new significant risk. The audit strategy is updated to highlight revenue recognition as a key focus area, and the plan is updated to add substantive procedures — testing a larger revenue sample, scrutinizing journal entries, and requesting management representations. Neither document can remain unchanged.

⚠️ Common exam mistakes

Treating audit strategy and audit plan as the same document — they differ in purpose, scope, and level of detail
Treating them as completely independent, sequential steps — in practice they are inter-related and changes in one must be reflected in the other
Finalizing the audit plan at engagement start and treating it as immutable — the plan is a living document updated as evidence is gathered
Omitting the nature, timing, and extent of procedures from the plan — all three dimensions must be specified for each procedure
