What type of review is Kathleen conducting after planning, assigning roles, and preparing materials for a code review?

Kathleen is conducting a Fagan inspection after she has planned, assigned roles, and prepared materials for the code review. A Fagan inspection is a structured and formalized process of reviewing code or design that follows a defined set of steps. This process includes assigning specific roles, such as the author, reviewer, and moderator, and preparing materials in advance, which aligns with the mention of planning and assignments in the question.

The Fagan inspection process consists of several stages: planning, individual preparation of documents, a group meeting to discuss findings, and the rework of the code based on feedback. This rigorous approach ensures thoroughness and helps in identifying defects and improving the overall quality of the code before it moves forward in the development lifecycle. It emphasizes clear communication and structured feedback, distinguishing it from other less formal types of reviews.

While other options might involve some review process, they do not encompass the same level of formality and rigor as a Fagan inspection, which is specifically designed to improve quality through a standardized methodology.
