Answer to Question 2

A walkthrough is a peer group review of any product created during the systems development process. During the review, users, management, and the development group participate through various roles. These roles are coordinator, presenter, user, secretary, standard-bearer, and maintenance oracle. The coordinator is the person who plans the meeting and facilitates discussions. The presenter is the individual who describes the work product to the group. Ensuring that the work product meets the needs of the project's customers is the role fulfilled by the user. The person taking notes and recording decisions or recommendations made by the group is the secretary. The standard-bearer role is to ensure that the work product adheres to organizational technical standards. The maintenance oracle is the individual who reviews the work product in terms of future maintenance activities.
