03:00 - Introducing the content of the 3 videos
02:30 - The activities, precedence, and duration
03:43 - Drawing the Arrow Diagram or PERT
10:15 - Calculating Start and End Times of the activities
This is the first video in a series of 3 about precedence diagramming and scheduling. In this short series, we will look into the arrow (ADM) and precedence diagramming methods (PDM), the different ways to complete the calculations, and draw the Gantt chart.
In the first video, I will explain how to draw the arrow diagram using the precedence information from the table and calculating the start and finish times of the activities.
In this method, the activities are represented on arrows and each arrow has one start and one finish node. These nodes are event nodes and they show the start and the end of the activity.
The first event node starts at time 0 and corresponds with the start of the project. The last node is the end node of the project. Each schedule has one start and one end node.
The calculations are done on a time scale and start at 0. It is best to compare with a time scale and chronometer where the counting starts from 0.
The ADM has to follow specific rules and the calculations are not as easy as the more recently used PDM. A specific characteristic of the ADM is that there can be dummy activities to show precedence information. Dummy activities have a duration of 0.

Thankyou for these valuable tutorials. I have a question that’s really confusing me. If you could help, I’d be so grateful.
Simplified:
Ten activities
Ten periods.
Eight of the ten last a fraction of a period, but are critical.
Two of the ten are long duration.
So, depiction on chart is accurate but almost unuseable.
Is there a technique for depicting duration in some sort of equivalent of a logarithmic depiction of “time” (duration), so that structure is apparent, but duration is not a 1.1 scale?
Great Explanation, i loved it
Very well explained Sir.
Quick question…Im attempting my PMP this month, I heard that this calculation is no longer being asked in PMP exam…also not there is in PMBOK 7
As I remember, there were always some calculations in the exams, but it seems that they are less today than before. Anyway, most of the exercises are really simple and you do not really have to know many formulas, only PERT, 3Point and EVM. When looking at EVM, it is good to grasp the principle (see some of my videos).
In PMBOK 7, there are still formulas and calculation, I just finished a course (on my website) covering PMBOK 7 and there are clearly calculations in it.

@@DeCeusterAcademy Thank you so much Sir fir your reply. Yes, I remember when I attempted PMP in 2017, there were lot more formulas than now. PERT, 3 Point and EVM is what I’m comfortable with now. Will surely go through your videos.
Thank you it was helpful...😊
You're welcome 😊
