According to IIA guidance, which of the following are commonly standardized workpaper elements?

Comprehensive and Detailed Step-by-Step Explanation:

Uniform Cross-Referencing System: A standardized cross-referencing system ensures consistency,

facilitates review, and allows quick retrieval of supporting documents. This is a best practice widely

recommended by the IIA in workpaper documentation.

Reference: IIA Standard 2330: Documenting Information, requires workpapers to be clear, organized,

and appropriately referenced to support conclusions.

Other Options:

Electronic Format Only: Workpapers can be electronic or physical depending on organizational policy;

there is no mandate to use electronic formats exclusively.

Inclusion of Original Documentation: Workpapers should include copies of key documentation, not

necessarily originals, unless required for specific reasons.

Thus, the correct answer is A.
