Question

Consider the following statements associated with critical path:

1. Critical path is the most important sequence of activities which has no float and which determines the project completion period.
2. Critical path is the largest path with shortest duration within which the project can be completed.
3. The difference between early start time and late finish time must be equal to the activity duration .

Which of these statements are correct?

Answer 1

The duration in the critical path is the longest. However, it is the shortest duration (minimum duration) within which the project can be completed.
Since the total float and other floats are zero on the critical path.
$\text{So}EST=LST\text{and}LFT=EFT\text{and}LFT-EST=\text{activity duration.}$
