Steps 4 & 5 – Run CPM Scheduling & Analyzing Results

These 2 steps are not trivial. Even though computers can schedule a project in milliseconds, it's important to grasp the underlying process and to review the output of scheduling to ensure it makes sense.

Now, we are moving to step number 4. After we have done the first three steps, we have divided the project into activities, we have estimated the durations of these activities, and we have set up the logic or the interdependencies among those activities. Now, we need to draw that network and perform CPM calculation or critical path method calculations manually or by the computer. Of course, these days we depend on computers and many people say, "Why don't you just say in this step instead of draw input that information in the computer?" And my response is that maybe I'm an old fashioned kind of person, but I insist that the person would know this procedure manually before you can apply it in the computer.

So, I usually in the classroom or in my seminars like this one, I insist that the person would be able to perform these kind of calculations by hand on small networks. And then when we demonstrate the ability to do it by hand, then we do it by the computers. And I usually use Oracle Primavera. Also, Microsoft Project is used widely.

We need to pay attention, in this step, on the imposed finish date. That's a very important point that will be discussed later on because we are now calculating the finish date of the project based on our assumptions of durations and logic. Now, does that satisfy the imposed finish date by the contract? Maybe, maybe not. So, t...
