I am in an Operations Management course in my senior year of the Business school, this course was the 4th to last class required for graduation for me. I am taking this course as a winter course, 1 semester in 3 weeks.... absolutely beyond me. THANK YOU SO MUCH! You have literally saved my life for something that was beyond me!
Thank you so much!!! God bless you. You have helped me so much with my Masters in Project Management. My teacher explains NOTHING. He expects us to read the book and understand everything by ourselves. Really, THANK YOU!!!
You literally have no idea how much I love you from the bottom of my heart. THANK YOU SO MUCH. Your teaching skills are brilliant and your voice is mesmerizing, plus using digital mouse makes it more fancy. Hope you business a level goes well, You SAVED me
u deserve my wholehearted respec. I thought I would skip the OR topic for my studies but your videos influenced me to prepare. thank you. Keep doing your awesome work.
Good god sir, I have a final exam in an hour and you've just saved my college career. I had a professor who totally botched explaining this for 8 weeks I wish i found you sooner!!!
I'm just a random high schooler so I didn't need this for an exam or anything but I think this is pretty interesting and a really efficient way of explaining! thanks for posting!
Haha nice. Well glad your spending your time in productive ways! If your interested in learning more about project management, you can see the whole series that I did at engineer4free.com/project management stay cool! 😎
very clear explanation putting the activity,Duration,ES,EF,LS,LF into boxes helped understand the forward and backward pass more easily. please put up a tutorial for person/day effort estimate too if you can! thanks!!
Cool concept...I would have never understood this without your help. My professor is online and he just tells us to read the textbook with no video examples. Thanks!
Ouch. This stuff is better taught in video than just text for sure! Glad I can help.. make sure you check out all the PM vids I did at engineer4free.com/project-management if you haven't already 👌👌
Aha with amount of people that blessed you in this comment section, you're most certainly going to heaven. All jokes aside you really are a life saver just helped me with my Project management, subcourse. Thanks again!
Sir you are genius. Your videos are so easy to understand. I couldn't attend my lectures and was finding this chapter hard but now I can solve examples real quickly
Yhoooooo thank you very very much for these videos now i learned what took me 3 months in just less than 10 minutes, very clear and your pace is also good i wish you are my professor
it's really cool how these diagrams are making sense..back and forth. i just wonder who came up with these and how it was made. it just makes sense like that lol
Hey Mike I have examples with float in videos 13-22 here: engineer4free.com/project-management video #22 might be of interest you you as it's a bit of a bigger nasty problem.
Hey Sanchita, when doing the forward pass, if an activity has multiple predecessors, take the largest EF of all predecessors as the ES of the activity. So in this case we have 8 and 9, so choose 9!
The Early Finish for B and Early start of D should be "8" for D its 9 .. you may want to correct it . . I understand its an error . The explanation is really GOOD
Hey Sabu, the EF of B is 8. The EF of C is 9. Because all relationships are simple Finish-to-Start, Activity D's ES is then limited by the largest EF of it's predecessors, which is 9. So ES of D is 9, not 8.
I do software training and have recorded lessons of my own. I commend you on the clarity of your explanation and delivery. I think one thing that may trip some of us is that not all node legends are consistent. In PMBOK 6, the duration goes top middle and float bottom middle. You have to be careful not to fall in the trap of mechanically adding and subtracting from memorizing the boxes. Thank you
Hey thanks for writing. Yup not only are node legends inconsistent, but also whether the project begins at 0 or 1. That also trips up a lot of people. I've found that if someone truly understands the logic, then numbering/labelling conventions used won't matter. It's all too easy to not really focus on why the logic works, and just blindly follow methods exactly. I do always hope that people watching these videos take the time to think about the logic :)
Hmmm, not sure exactly which first lesson you’re referring too. This video is part of a greater playlist, and I generally introduce one concept at a time in each video to keep them to a reasonable length. See videos 1 - 15 here: engineer4free.com/project-management for the first few topics in project scheduling
Excellent explanation, I have been reading my book for quite a while now, and was struggling to finish hw, but now it seems really simple to do. Thank you!!
You only do one of the following equations: TF=LF-EF or TF=LS-ES. You only do one of them because both expressions reveal the same and correct number. Don't add both together.
I have a question concerning total float. I have network diagram and has 9 activities, three of them have the total float which is in non-critical path. one activity has 5 days, another one has 5 and other has 4 days. the question gives me 4 options. a.5 b.9 c.12 d.14 what it the right answer, and why? thank you in advance, Mohammed
Hey sorry I don't understand the question. If you upload a picture of the table of dependencies or the network diagram to imgur and link it here I can help you out!
As far as I know, total float is a term that is used per activity basis, not project basis. Total float is the amount of time any given activity can be delayed without delaying the project end date. Total float talks about an individual activity's impact on the project, not the impact of a collection of activities. If this is a homework problem and you won't have the opportunity to talk to your professor before it is due, my best guess is that they are looking for answer D: 14 days which is just the sum of all of the total floats in the problem. That's a pretty meaningless number though,, because the number "14" doesn't apply to any given activity, it can't be used without further clarification that those 14 days need to be allocated 5, 5, 4 to D, E, H respectively. If this is just a practice problem, or you have the chance to go talk to your prof before the homework is due, then go ask what they are really after here. The wording of this question is sloppy in my opinion. It could be clarified by asking something like "How many days of total float are available across all of the activities in the project" and even then, the answer to that would be 14, but 14 is not a helpful number to anyone for this problem. A better wuestion would just simply be "write the total floats of each activity in the project," which you did in your work already. You did the work correctly and found all the total floats, the question is just a bit silly.
If EF for A is 5, Shouldn't the ES be 6 for B and C. I'm assuming A needs to finish before B/C can start. Also is float the same as Total Float since the calculation is the same?
The way that I write ES and EF comes from the way I draw Gantt charts. Take a look at this video: th-cam.com/video/NcOmJSrXYoQ/w-d-xo.html each sort of "column" represents a day, which means then that 0 represents the beginning of day one. 1 represents both the end of day one and the beginning of day two. 2 represents the end of day two and the beginning of day three. 3 represents the end of day three and the beginning of day four, and so on. It's weird to think this way at first, but staring at the Gantt chart for a little while, and then cross checking with a network diagram should be enough to see how the numbering system works. Let me know if you are still confused about it! Edit: here's an image with both Gantt chart and network diagram together for your reference: www.engineer4free.com/extras/gantt-chart
Understood in 4 minutes what could not be understood in the last 4 months...Good on you sir!
Awesome! Glad I could help 🙂🙂

This is very helpful. Thank you very much sir
You’re welcome, thanks for watching!!
Well explained. Thank you!
Glad it was helpful!
What if it is a larger diagram with multiple steps that have float? Do you add them?
Hey Mike I have examples with float in videos 13-22 here: engineer4free.com/project-management video #22 might be of interest you you as it's a bit of a bigger nasty problem.
Ty for that! However, should Activity D have an ES of 8 rather than 9? I'm confused :(
Hey Sanchita, when doing the forward pass, if an activity has multiple predecessors, take the largest EF of all predecessors as the ES of the activity. So in this case we have 8 and 9, so choose 9!
Engineer4Free Ah of course! Doh! Ty! Awesome tutorials! ❤️❤️❤️
Really easy to understand. Thank you very much
you explained it better than my teacher. thanks lets hope i do well on my exam
Very good presentation for P6 learner.
The Early Finish for B and Early start of D should be "8" for D its 9 .. you may want to correct it . . I understand its an error . The explanation is really GOOD
Hey Sabu, the EF of B is 8. The EF of C is 9. Because all relationships are simple Finish-to-Start, Activity D's ES is then limited by the largest EF of it's predecessors, which is 9. So ES of D is 9, not 8.
i like his way of talking ! its clear !thanks ^_^
+Joanne thanks for the comment! ^_^
It really helps me. Thank you.
Awesome thanks for letting me know!!!
Tnk u professor ur greate u exeplain every time thing in detail
Thank you!!!
I had to write a supplementary exam because my lecture spent 1 hour explaining this and even afterwards I didn't understand a thing. Thank you sir
Glad I can help you out Joseph!
I thought PM was tough and i hated the subject. My exam is in 2 hours and I almost gave up. Thanks! There should be a TH-cam University FR!!!
That was amazing! Thank you so much!

why didn't you use the first lesson example to solve the total float/slack? Thanks

thank you so much for making this video. it is really useful.
No worries Mohammed, glad these videos are helping you!
You re amazing in explanation ❤
Thanks Saba
Thank you very much, this is very useful for me.
When you do the backwards pass, why do you use the smaller number? What's the logic behind this?
What about using a time-scaled dependency chart?
Are you referring to Gantt charts? If so, you can check videos 1-3 here: engineer4free.com/project-management
Excellent explanation, I have been reading my book for quite a while now, and was struggling to finish hw, but now it seems really simple to do. Thank you!!
Glad to hear it! Make sure you check out all my PM videos at engineer4free.com/project-management if you haven't already
Thanks just what I needed
sir how to determine total float if sum of late start-early start is not the same as late finish-early finish..i cnt find in the other vid as well
You are my savior Thank you so much😁😁😁😁
Glad I can help Rose, if you haven't already, do check out all the PM videos that I did over at engineer4free.com/project-management 😁😁😁😁
I want to ask in 0:41 why the LS number is 6 in Activity
LS = LF - Duration, so 6 = 9 - 3
Thanks so much you save my Exam assignment Project little part in network diagram parts I was understand the concept about it
Awesome, glad I can help! Make sure you check out engineer4free.com/project-management for all of the PM videos that I made!
Thank you. great video! you're a genius sir.
Thanks a lot ofel!
Really helped, thanks!
great explanation sir.🗿🗿😍...amazing ...amazing sir...very helpfull.these video series 🤟thank you sir.
Wao. What an excellent explanation 🙄
Thank you so much! This helped a lot :D
Awesome, glad I could help!!!
@engineer4free, what stylus are you using?
Hey Clive, I use an Bamboo Wacom drawing tablet, you can find all the hardware and software that I use here: engineer4free.com/tools
Sir in activity B why isnt the total float equal to 2 . 9-8 +6-5 = 2 ?
You only do one of the following equations: TF=LF-EF or TF=LS-ES. You only do one of them because both expressions reveal the same and correct number. Don't add both together.
I have a question concerning total float. I have network diagram and has 9 activities, three of them have the total float which is in non-critical path. one activity has 5 days, another one has 5 and other has 4 days. the question gives me 4 options.
a.5
b.9
c.12
d.14
what it the right answer, and why?
thank you in advance,
Mohammed
Hey sorry I don't understand the question. If you upload a picture of the table of dependencies or the network diagram to imgur and link it here I can help you out!
Can I send the network diagram question to be clear to understand ?
Yes. Please share a link to it in the comments here, like imgur, google drive, etc so someone else might benefit from it too!

i agree with you. As per PMP this is wrong. ES should be 6 and not 5. Confusing students.
Good job
Really helpful
Thanks for letting me know =)
Thank you

brooooooo ur explanation is way better that our mf professor who sleeps with research papers
Thank you!
Thanks man
