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 :)
Missed my lecture, could spend 1h going through lecture notes or watch your 7:13 video, thanks for saving me time it was very concise and well explained.
+There is no spoon (Ze Engineer) Thanks for the compliment! You can find the rest of the PM tutorials I made here: www.engineer4free.com/project-management good luck in your class!
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!
i attend uni for my MSc in PM and I swear to God sometimes I feel lost and don't know what they're talking about- I luckily found this channel and its easy to understand thank you so MUCH I shared it with my friends :D
I wrote nothing on my Continuous Assessment Test today since I missed the class and had no notes..... But as we talk am now a master in Network Diagram even in dreams I can work it out without a Fail... Thanks ... In our local dialect we say Thengió Munó
Thank you so much sir, i spent 2 hours trying to figure out how to find out Free Float and Total float , i was many YT videos but none of them were explaining using this BOX Diagram method...Finally found your lectore...tysm, you are a life saver
Thanks! Might as well do it correctly :) Make sure you check out the rest of my PM videos at engineer4free.com/project-management if you haven't already. Cheers!
I'm really happy that I can help you out, make sure you check out all my free PM videos at engineer4free.com/project-management if you haven't already :)
Wow. Thank you soooo much. I was having a hard time understanding and calculating floats while studying for my CAPM exam. Now I can confidently say that I'm ready for any schedule questions!
Thank you very much for your videos. I went through all the videos that I could find about this topic and presented by you. I have a firm understanding on this topic now. Again, thanks.
+Heiress983 Wow that's good to hear! Glad I could help! If you need any other tutorials you can find the rest that I made here: www.engineer4free.com/project-management Thanks for sharing your success story :)
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?
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?
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: ua-cam.com/video/NcOmJSrXYoQ/v-deo.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!
why successor's ES is on the same date of predecessor's EF? Should ES date of successor add one day more from EF of predecessor’s? You must wait for previous activity to finish and start ES on next activity. It doesn’t mean scenes when you put them on the same date.
It comes from how the giant chart is drawn. Watch this video first: www.engineer4free.com/4/how-to-draw-a-gantt-chart You can see that 0 represents the beginning of the first day, 1 represents the end of the first day AND the beginning of the second day. 2 represents the end of the second day AND the beginning of the third day. 3 represents the end of the third day AND the beginning of the fourth day. And so on. So in that video, Activity A has a duration of two, so it starts at the beginning of the first day (0) and ends at the end of the second day (2), and Activity B then starts on the beginning of the third day, which is also marked by 2. On the network diagram, these come across as the activity’s Early Starts. Hope that helps clarify it for you!
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?
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.
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!
Hey thanks for the suggestion. Probably won't get around to it any time soon as I'm working on a different subject, but I'll keep a note of it for the future
+Shehzad Akhtar ahah thanks for the feedback! You can find all 45 free PM tutorials I made here: www.engineer4free.com/project-management.html Good luck studying!!
Total slack is a value given individually to each activity, not the entire project as a whole. It's the amount of time that any specific activity can be delayed, without delaying the finish date of the overall project.
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!!
Thanks for the feedback, means a lot. Plz share my vids with some peers if it might help them out!

@@Engineer4Free I watched 50 percent of your playlist. Wonderful job. I Have a test coming up. Just revising things😆
Thanks very much for this explanation i got it really especially the FF calculation
Excellent demonstration.
Thanks!!! =)
Excellent explanation. This really helped me.
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.
I tried, it might make a mistake , look at the F and E activity in the video
@@AnotherStudent96 no mistakes
FF activity = ES successor - EF activity
Mohammed Al-Mashehdi Can you help for the formulae of independent float?
@@mohammedal-mashehdi1271 Thanks a lot
@@deep77thakkar whats the formula for independent float?
Great explanation, and it helps me prepare for my test tomorrow!!!
Thumbs up!!!!
Great job on explaining the difference between TF and FF
Thanks!!! =)
Thanks man! I have a midterm in 2 days and my teacher couldn't explain it like you did in this video.
thanks wallah really appreciate it you explain it in very simple way
Explained really well -- Thank you
Thank you so much. I have passed because of you❤
That's amazing!! So glad to hear it ♥️
Well explained, thank you for this
You are welcome! =)
It really helped a lot, A big thank you!
Great, thanks for letting me know!
so the critical path is A, B, D, C, E, G, F, H? Or A, B, D, G, H? Surely you would miss completing C, E and F if this is the case?
This is fantastic, I find this helpful. Thanks
Glad to hear it!!! =)

Good explaning thanks
Thanks Mohammed!! 😁
better then my prof...

this is reality for your info :)
really he doesn't make even half of what you do :(
hate to say that,but it is a damn fact
Thanks bro
Any time
Plz also make video to find independent float
thank you

You're welcome Rick, thanks for watching!
So how much is the total slack time? 15 days?
Total slack is a value given individually to each activity, not the entire project as a whole. It's the amount of time that any specific activity can be delayed, without delaying the finish date of the overall project.
thank u
ur welcome
CAN the total float number in one box give different numbers??? or dose that mean a mistake was made in calculating?
Each activity can only have one value for total float
Thank you, my note did a horrible job
Thank you 💗
You're welcome!!!
thanks! good explanation
thanksmate !
I think there is a mistake in Early start calculation, formula for calculating ES is EF(S)+1 so kindly check & reupdate
thank you so much.. i think i will pass :D
Thanks
You're welcome Saad!
