As a result, many countries and many health-related organizations set to work trying to uncover both effective treatments as well as a vaccine. Developing any of these three possible remedies is useful - developing all three would be wonderful. The three are a vaccine, isolation of the antibody, . and a treatment One of these organizations is Toronto's University Health Network. J.Z. Smith, the project manager assigned to organize the employees involved, has asked you to develop a network diagram to outline the efforts being undertaken. The project team gathered the activity time estimates and the dependencies shown below.
