The correct answer to this open question is the following.
There have been some rumblings within the firm that this development project is not necessary so John and others feel it is important to explain the reason for the project at the outset. The name that goes next to this point on the agenda is "Tom."
The reason why is that John is the leader of the project called Joint Application Development or JAD. Tom is the second member of the hierarchy of the project. Tom is the representative of top management. Then, the other members of the group are Jennifer, Alen, Ian, Linda, Alex, and Clark. Jennifer is a manager. Alex and Linda are analysts of the system. Clark is the recorder. Finally, Ian and Alen are users. So in hierarchical order, Tom should be the one next on the agenda.
