Dr. Adinombe Watage, deputy director of the Family Planning Research Center in Nigeria's Over-the-River Province, was assigned the task of organizing and training five teams of field workers to perform educational and outreach activities as part of a large project to demonstrate acceptance of a new method of birth control. These workers already had training in family planning education but must receive specific training regarding the new method of contraception. Two types of materials must also be prepared:

(1) Those for use in training the workers,

(2) Those for distribution in the field. Training faculty must be brought in and arrangements made for transportation and accommodations for the participants.

1. Some of the tasks in this project can be done in parallel.

Prepare a diagram showing the required network of tasks and define the critical path. What is the length of the project without crashing?

2. At this point, can the project be done given the personnel constraint of 10 persons?

3. If the critical path is longer than 60 days, what is the least amount that Dr. Watage can spend and still achieve this schedule objective? How can he prove to Path minder Foundation that this is the minimum-cost alternative?
