A competitor of 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:

Develop an activity schedule for this project using early and late start and finish times, compute activity slack time and define the critical activities.
A group of developers is building a new shopping center. A consultant for the developers has developedthe following table of activities, durations and predecessors. Determine the earliest start times andfinish times, latest start and finish times, activity slack, critical path and duration for the project. Thereis a Bonus for finishing the project at 90% of the projected date. The bonus for early completion is$50,000. Which activities should be crashed, if the cost for 1 week reduction, for any activity, is $3500per week, and what is the total cost of crashing? And, Net Bonus, if any.
