Final answer:
The statement is true; a well-documented audit allows an experienced auditor without prior engagement experience to replicate the work and reach the same conclusions, ensuring audit accuracy and integrity.
Step-by-step explanation:
The statement is true: An audit is considered well-documented when an experienced auditor with no prior experience on the engagement can replicate the audit work and reach the same conclusions. This level of documentation is essential for ensuring both the accuracy and the integrity of the audit process. A well-documented audit trail allows for the audit to be reviewed by others, which can serve as a check against potential mistakes and biases, as experts often have a good initial sense of the answers before a detailed analysis. Such rigor in documenting the audit process is akin to well-documented program evaluations, which help in identifying successful programs for replication, and to the audit studies often used in experimental research to ascertain cause and effect. In the context of scientific research, similarly, experiments must be reproducible, and for conclusive results, they have to be repeatable by other observers, maintaining the same level of authority and documentation.
