A team member is assigned to be the moderator. Their responsibilities will include the scheduling of meetings, reporting the results of inspections, and following up on issues that arise. Another team member is assigned to be the reader. Their responsibility is to break down for the team what is written in the work product. One team member is assigned to be the recorder who notates the defects raised during the inspection. All the team members act as inspectors in that they try to find errors. Finally, there is the author. This is the team member that created the new product that is being inspected.
