What is the use of critical path analysis as a tool?

The use of critical path analysis as a tool:

a. It is good visual communication and planning tool for effectual time management.

b. It displays clearly interdependent relationships which exist among the different activities or events to be finished.

c. Arranges activities or events in an optimum sequence of events permitting a project to be completed into the most capable time possible.

d. Elapsed time (or estimated time) to complete the project can be computed.

e. Highlights which activities those are ‘critical activities’ for example those tasks that should be completed into their planned time, or else the elapsed time or approximate time of the project will not be obtained.

f. Enables more effectual resource planning, resources can be diverted away by ‘non-critical’ to ‘critical activities’ as like staff could be moved by one task to other, must problems of overrunning arise on critical activities. It does suppose that resources moved are directly substitutable among tasks.

g. Highlights ‘float times’ for each and every activity for example the amount of time an activity or assignment can slip past its planned completion time, but without delaying the elapsed time or approximate time of the project. All the critical activities consist of a float time of zero, since each should be completed into their planned completion time, or else the elapsed time of the project won’t be accomplished.
