37) A hatmaker, fresh off a very successful showing at Lidzapalooza is excited about the prospects of
providing the finest chapeaus to meet the needs of his energized customer base in the coming year. He
and his space designer have identified seven activities that are necessary to expand his small shop. For
the sake of simplicity, and to avoid giving away any trade secrets, the activities have been identified by
letters A-G. The activities, their time estimates, and the precedence requirements structure are listed in
