Explanation:

• Critical Path Analysis is presented using the circle and arrow diagrams.
• Earliest Start Time = the earliest possible time of starting the activity
• An arrow running between two event circles shows the activity needed to complete that task.
• All arrows run left to right
• Time for doing just task E = 8 hours (as shown in the figure)
