PERT - actually it is a CPM problem

a PERT chart. This is a chart of a project consisting of six tasks. In the first table you see all the tasks listed along with completion time and task dependencies. Note not all the tasks need a prior task to be completed, that is they are independent.

The second table lists the paths or completion steps for sub-tasks and tasks dependent on them. This project could be anything you like, building a house, remodeling a house, building a car manufacturing plant, planning a wedding, etc.

Which path is the critical or most important path? Why is it the Critical Path and what is the significance of this path?

Thanks in advance!
