FORWARD PASS
We calculate the ES and EF values using a forward pass where the ES
of an activity is the maximum EF of all the predecessor
activities.
BACKWARD PASS
We calculate the LS and LF values using a backward pass where the
LF of the activity is the minimum of all the successor
activities.
SLACK
Slack is the value which is determined by subtracting EF from the
LF or ES from the LS.
CRITICAL PATH
Critical path is the chain in the project network where the slack
value of all the activities is 0, what this means is that any delay
in these activities would result in delaying the entire
project.
CRITICAL PATH = 1-2-4-7-9-10
