A competitor or Kozar International Inc. has begun marketing a new, instant developing film project. Kozar has had a similar product under study in its research and development (R&D) department but has not yet been able to begin production. Because of the competitor's action, top managers have asked for a speedup of R&D activities so that Kozar can produce and market instant film at the earliest possible date. The predecessor information and activity time estimates in months are as follows: Immediate Optimistic Most Pessimistic Activity Predecessors Time Probable Time Time A 2 2.5 B A 4 5 6 A 3 4 D B, C 1.5 6 7,5 E 3 4.5 9 F 7.5 12.5 F 11.5 14 a.
