### Mnemonic: CID TIE

Letter	Benefit	What it Means
C	Coordination	Assists in coordinating work done by others — e.g., experts, internal auditors, component auditors
I	Important areas	Helps the auditor devote appropriate attention to high-risk or significant areas of the audit
D	Direction & Supervision	Facilitates direction, supervision, and review of engagement team members' work
T	Team selection	Assists in selecting team members with capabilities matched to anticipated risks, and assigning work appropriately
I	Identify problems	Helps the auditor identify and resolve potential problems on a timely basis
E	Effective & Efficient	Ensures the audit engagement is performed in an effective and efficient manner

### The Outcome of Good Planning

Reduces audit risk to an acceptably low level
Reduces the risk of an inappropriate audit opinion
Prevents last-minute surprises that could compromise the audit

Worked example

### Example 1

An auditor planning the audit of a manufacturing company identifies inventory as a high-risk area early in the process (I — important areas). The most experienced team member is assigned to inventory counts (T — team selection), and an inventory valuation specialist is engaged (C — coordination with experts). Problems with obsolete stock are identified and resolved before the reporting deadline (I — identify problems timely). The result: a more efficient and accurate audit.

⚠️ Common exam mistakes

Treating audit planning as a one-time activity completed before fieldwork begins — planning continues and evolves throughout the entire engagement
Thinking planning is only about scheduling and resource allocation — it also covers risk assessment, materiality determination, team capabilities, and expert involvement
