Doug Casey is in charge of planning and coordinating next spring’s sales management training program for his company. Doug listed the following activity information for this project:
A. Draw a project network.
B. What are the critical activities and what is the expected project completion time?
C. If Doug wants a 0.99 probability of completing the project on time, how far ahead of the scheduled meeting date should he begin working on the project?
Draw a network representation of the project (nodes = activities, arrows = precedence constraints). Provide early start/early finish as well as late start/late finish times for all activities.
What is the duration of the project, and which tasks are on the critical path?
