# Project Schedule and Critical Path

Based on the material covered in class and using the following information about the activities of a project, please identify:
1. the shortest amount of time in which the project schedule can be crashed without exceeding \$7K and
2. the project critical path that resulted from crashing the project

Please see attachment for data set.

#### Solution Preview

First draw the network diagram and calculate the critical path and expected duration of the project.

Please see attachment for complete solution.

Notes:
• An activity should not be crashed if there is not a reduction in the duration of the project. Remember that crashing is investing financial resources to speed up the project. So why invest if there is not a ...
