A Brief Introduction to the Critical Path Method

This course has a large focus on Critical Path Method Scheduling, but what is the Critical Path Method exactly? Dr. Mubarak will illustrate the Critical Path Method with a unique analogy.

This video, we're going to talk about the critical path method. In fact, the critical path method is the most important part about the whole course. The critical path method was introduced first in the 1950s, and it came as a jump from the bar charts. Bar charts were great as simple method, but they were very subjective. When I do a bar chart, people may ask, "Why did you put this bar here or there?" or, "Why this bar is long or short?" It's all subjective. The critical path method try to make it as objective as possible, as scientific as possible and use the estimate of the construction people in a scientific way.

So what is the critical path method? It's a scheduling technique using networks for graphic display of the work plan. Network calculations determine when activities can be performed, the expected completion date of the project, and the critical path of the project. The key word here is that network calculations determine. It's not you subjectively say, "I want to do this on the 11th of March, and I want to finish this on this and that," no.

You are in this case giving an input. The input as we will see later on is the activities, their durations, and how they interact together in a logical way. And then you leave this to the CPM calculations to tell you when each activity will start and each activity will finish. In order to demonstrate the conc...
