Draw the network diagram linking all the activities in a way that it shows if there exist any
preceding activity/activities before starting each of the mentioned activities in the above
table,
ii.
Showing the earliest start time, the earliest finish time, the latest start time and the latest
finish time of each of the activities in the project determine the completion time of the
project and the critical path.
ii.
Find the slack time (delay time) of each of the activities, the critical and the non-critical
activities.
Find the minimum possible completion time of the project by considering the crashed
completion times and the minimal total cost of that crashing the project.

6A. Draw the Network Diagram, and identify and discuss the project duration and the critical path using the following activity notation:
the first pic:
First: Draw the precedence diagram.
Second: Using the notation given identify the duration of the project: you can type it.
Third: identify the critical part and explain the critical path.
Fourth: Explain your answer. This can be done by describing the process and the observations done once the answer has been found.
