Final answer:
A review session led by the author is typically a walkthrough. This informal process is aimed at providing insights and gathering feedback, unlike the more formal inspection or audit.
Step-by-step explanation:
If a review session is led by the author of the work product, the type of review is typically considered a walkthrough. In this process, the author of the document or code leads a team through the product and provides explanations and clarifications as needed. It is an informal process with the primary goal of providing insights into the document contents and gathering feedback. A walkthrough differs from an inspection, which is usually a more formal and rigorous process of error detection, and from an audit, which is a systematic review of an organization's records and operations by a qualified person or group.
