Which statements about walkthroughs are correct?

Walkthroughs are informal reviews that involve discussing a product or a process with a group. One of their primary characteristics is that they are often led by the author of the material being reviewed. This structure promotes an open environment where participants can learn from the author about the logic and thought processes behind the work.

The goal of a walkthrough is not primarily centered on defect identification; instead, it focuses on sharing knowledge and facilitating learning among the participants. This collaborative approach allows team members to gain insights into the content, thereby enhancing their understanding and potentially contributing to the overall quality of the product.

In addition, walkthroughs do not require all participants to have technical expertise. They can include a diverse group of stakeholders, allowing for various perspectives and insights, which is valuable for learning and understanding the material deeply.

Thus, the statement that walks through being led by the author and used to aid learning aligns well with the nature and purpose of walkthroughs.
