Attending a very expensive PM course, but hardly any one of the lecturers can compare to your simplistic way of teaching. Thank you very much!!

@Engineer4Free 4 года назад

Thanks for the feedback, means a lot. Plz share my vids with some peers if it might help them out!

@vallekinloch7421 4 месяца назад

aja.. you fell for the course as well, haha.. me too. Did the course.. wasn't what I expected.. but it at least offered a good study guide.. anyways, this video rocks :)

@Nice_nightmare 2 года назад

Thank you so much! im taking project management as an online course and besides the book, nothing else can explain this to me. This along with the other videos were extremely clear, easy to follow, and all around helpful for me to understand. I have to do this kind of problem for my final and i was sure i was going to fail until I watched these videos!

@manologodino941 7 лет назад

Thank you very much for this very clear explanation!! One small question, what happen when you have Start to start or finish to finish linked tasks (even including lead/lag), how to calculate the free float? Using the expression on the video obviously fall into negative values which makes no sense as per the concept of float, but I guess in that case the calculation expression mustchange right?

@ianhayes9101 8 лет назад

You make the computation of free float a bit more complicated than it has to be. Instead of subtracting ES and duration, just subtract EF.

@AnotherStudent96 5 лет назад

I tried, it might make a mistake , look at the F and E activity in the video

Awesome video. But please please can you upload the calculation for free float with lead-lag reltionships. There's literally nothing out there on the web for this. Thank you!

@juhip1 6 лет назад

excellent video - some videos assume the ES of 1st activity as 1 and keep subtracting 1 from every successor activities ES , you have assumed 0 and are not subs 1 in forward pass . What is the correct method?

@Engineer4Free 6 лет назад

Neither method is truly more "correct" than the other, they follow the same logic, but are just shifted from each other by one. If you are in school or studying for a certification, then just follow the method that your instructor is using. The reason that I start with zero stems from the way I label and draw my Gantt charts, you can see in this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-NcOmJSrXYoQ.html where the column "0-1" represents day one, so therefore 0 represents the start of day one, and 1 represents the end of day one, but also the start of day two. And so on... Hope that helps, thanks for the question!

@caveshlin 3 года назад

Great vid! Quick question. If I have three activities with no predecessors, how do I construct the network? Will it have a 'start' node that bursts into the three activities? Or will I just have three separate activities starting points?

@Engineer4Free 3 года назад

For an Acticity on Node diagram like this one, you will not have a single start node that bursts into three. You will have three seperate initial nodes, all with ES=0. Organize them all on the left hand side, one over the other, and then use the logic from the table of dependencies to draw out their successors. When you do the forward pass, set all three initial activities' ES to zero, and count up as usual. When you do the backward pass, at least one MUST have a LS = 0 . The other two may have LS = 0, or an LS greater than zero.
