a. 1. The expected regular times for each activity using PERT are derived
by using statistical methods to resolve the uncertainty involved in the activity

2. The term “critical path” defines the longest path of activities calculated by totaling the
individual expected activity times in sequence that are required for completion of a
project. The critical path represents the total time that will be needed to complete a
b. 1. Grace Vander’s accelerated
delivery schedule is unsatisfactory in cutting 10 days from the total project
schedule because not all of her crashed activities are included on the
Chapter 1 Page 6
2. Below is a revised accelerated
delivery schedule that meets both objectives: 1. delivery of the first plane
2 weeks (10 working days) ahead of schedule, and 2. at the least
incremental cost to Coastal.

All of the paths need to be evaluated when reducing a project’s
completion time. However, the selection of activities to crash should be
taken from the critical path first and then the activities should be selected
in order according to the smallest crash cost. The critical path ABGEFJK
(65 days) is reduced to 55 days; however, the critical path changes as a

14. CONCETPTUAL DESIGN
True, object-oriented design is a bottom-up approach that reuses existing modules.
However, if we incorporate an analysis phase that determines a top-down
assessment of the needs, we can then determine if any modules currently exist
