Answer to Question 1:
PERT (Program Evaluation Review Technique) is basically a project management tool
that is used for scheduling, organizing and coordinating the tasks in a project. The PERT
methodology is developed by U.S. navy in 1950 for managing the Polaris missile program.
PERT chart is a tool that is used for making plan tasks in a project (Hajdu & Bokor, 2016). The
PERT chart help to make the schedule of the project easier and the team members can coordinate
for accomplishing work. With the help of PERT, the project developer can create three various
time estimates for a particular project. The first estimate that can be made is measuring the
shortest amount of time that each task will need, the second is the most estimated amount of time
and the third is the longest amount of time that the tasks will need if things are not planned
(Bastos et al., 2017). PERT is a process that is calculated backward from fixed date because the
deadline of the contractors cannot be changed.
The characteristics of the PERT are as follows:
 PERT helps to manage new projects.
 PERT can solve models that are under uncertainty.
 Depends on time.
 PERT is event oriented.
Answer to Question 2:
Earliest start time- Earliest start time of an activity is the earliest time at which the
activity starts.

Latest start time- Latest Start Time is latest time at which the activity actually begins and
ensures to complete the project on time (Mazlum & Güneri, 2015).
Earliest finish time- Earliest Finish time is earliest time that the activity is expected to
end.
Slack time- Slack time refers to the time delayed between the earliest start time and latest
start time (Agyei, 2015). The slack time also includes time delay without changing the duration
of the entire project.
If an activity has more than one predecessor, for calculating the earliest finish time, the
predecessor that has the least time activity is to be taken. So, Earliest Finish Time will the
cumulative time for the least time predecessor and the own time of the activity to complete the
work.
The early start time of the D activity for Bart’s Ski Trip is 0.5, and
The latest start time of the D activity for Bart’s Ski Trip is 4.0
So, slack time can be calculated as:
Slack Time= Latest Start Time – Early Start Time
= 4.0 – 0.5 = 3.5 hours.
Answer to Question 3:
Critical Path Method is mainly based on the algorithm of scheduling to set up project
activities (Liberatore, 2016). There are many essential techniques for using the Critical Path
Method for constructing a model in a project. CPM includes all the activity lists that are needed
