PMP Exam - Critical Path Part 1

Sir Ganttalot helps you prepare for the PMP exam by explaining Critical Path and Float/Slack analysis. This is a two part lesson. Part 1 covers a quick and easy "eyeballing" method to identify the Critical Path in a project network and to determine the float/slack for non-critical tasks. Part 2 explores in detail the forward/backward pass approach.

that was great.... I do not have to do any early start, late start calculations any more!!

[SirGanttalot]

Thanks for the feedback, I am very pleased that the video was helpful for you.

It is still important to know that Float/Slack is LS minus ES, or LF minus EF, even though you most likely won't have to calculate values for ES and LS. You might, for example, get a question where you are told that an activity has an ES of 15th March and a LS of 15th March. The question will ask if the task is critical, and of course it is, because slack is zero in this case. (Beware the Ides of March!)

It is possible. You need to have, and be able to list, experience managing projects or leading activities within projects. How much experience you need depends on if you have a Bachelors degree. If you do, you need to show 4500 hours experience over at least 3 years. If not, then 7500 hours over at least 5 years. You also need to have 35 hours of project management training. Go to the PMI web site and search for and download the "PMP Credential Handbook" for more details. Good luck.....

i did find this quite helpful though for my exam, we were told to set out the diagrams a little differently.

[SirGanttalot]

There are several different ways to set out the diagrams. In fact, there is more than one type of diagram altogether, the "Activity on Arrow" diagram. I'm sure the way you learned is just fine. The key thing is to understand what the REASONS are for the steps you take. So, learn an approach that you like, and stick with that. Good luck.

@SirGanttalot : Thanks a million for the videos. I am appearing for the CAPM exam next month. The videos are extremely useful and it is free. WOW! If I were is UK I would have certainly signed up for a formal training with WestMurray.

[SirGanttalot]

Thanks for the comments and good luck with your exam. We are US-based rather than UK. However, we will shortly be starting on-line web-based seminar PMP and CAPM preparation courses, as well as other on-line and on-site courses. Please stay connected for more information. Regards.

To be able to sit for this exam, we have to accumulate at least 3 years of experience. I contacted the PMI local chapter to find out how it is possible for us to gain experience and satisfy the hour requirements, nobody ever responded me. It's so frustrating. What's the point of taking the exam prep class if we can't find ways to accumulate the years of experience to be able to sit for the exam?
