I have never really unerstood PERT and thought it was something very tough. But this man has made it look like childs play. he's so good. Thank you sir for being present on youtube. Thanks!
I find this so much easier to understand now. We have been taught to work out the ES, EF, LS, LF in a table format after drawing out a network diagram. I find it much easier to use the PERT diagram you have shown. Thank-you!
Thank you so much! Back in college, I had a steep learning curve & thought PERT/CPM was difficult. Now, I know our prof was being difficult. She just made us put numbers on top of the nodes (tasks) for the ES-EF calculations. I couldn't for the life of me get the numbers to add up correctly. The key was really helpful. This helps a lot since I'm now managing our family's manufacturing firm. It's actually pretty easy.
Im so grateful for the patients you displayed in explaning the PERT CPM. You have added emmence value to my learning. Do you perhaps have simliar videos explaining Simulations done in Excel?
superb explanation i dont know about pert tmrw is my exam with so much fear i just went to youtube finally i got it thanks a lot for posting this.you tube is not only for entertainment but also for studies.
this excellent staff - now i understand PERT diagrams better! Keep up the good work. By the way how can i get the full set of vieos on project management
Dear Romrio, first of all thanks for sharing this class with the world, on the other hand there´s something I don´t have completely clear and is the probability of finishing the project in 27 days, let me tell you the way I would calculated: Z value is - 0.33 Then I take this number in the Normal distribution table and cross Z = 0.3 with 0.03 and gives .6293 wich means the project has the 62,93 % probabilty of finishing in 27 days... Please let me know if I´m wrong, thaks a lot.
I think there is a typo in your table. mine is 0,1293. and since it is in the left side , you need to calculate the "remaining" area so you take your value out of .5, and that will be the remaining area.
Hello sir... In our que they just gave that Z(1.34) =0.4099,they didn't mentioned about variance or even standard deviation. Then what value should we take for variance or sd?
thx for your sharing sir.. but i would like to ask you a question, how can u get the a, m and b time... is that just from the historical data or jus the assumtion from the estimator?? or maybe other.. now i'm doing my project to get that value, if you don't have a historical data from the same project.. and you are not the estimator...
A = Optimistic Time = Shortest possible time to complete the activity if everything goes fine. B = Pessimistic Time = Maximum possible time which an activity can take to complete. M = Most likely time = It lies between A & B. It assumes that things go in normal way with a few setbacks. So yeah, basically they all are estimates. And if you have EXACT data based on historic information, you simply use CPM. CPM - When you have exact data. PERT - When you work with estimates and uncertainties.
I'm in finance dept of a tractor industry. Recently I underwent a management development programme sponsored by our company. Now I can take up a project using PERT tools. Hats off Mr.romrodemarco
variance of expected time of project is sum of variance of the events. So add up squares of (pessimistic-optimistic time)/6 for each event along the path

Wow! 10 years ago video! This is the best for explianing the PERT CPM! Thank you so much Sir!

+10521577A OMG SAME!!!!
Understanding this 0.5 thing was never ever so easier for me! Thnk you sir.
thanks a lot sir! I was so scared of pert going through book. u ve made it so simpler. thanks a lot.
Thank you so much I'm writing in an hour and I learnt more from you than I did from my Lecturer
thanks for healing my ignorance on pert analysis
excellant explanation by the tutor. Very thankful to him.
Im so grateful for the patients you displayed in explaning the PERT CPM. You have added emmence value to my learning. Do you perhaps have simliar videos explaining Simulations done in Excel?
This guy is amazing... Highly recommend him to anyone who struggled with PERT like me
Thank you so much, better than my lecturer
Thank you very much sir....you made the critical things very easier...
very good sir... its really helpful... every concept cleared.. Thank you.
Really great videos, I have learnt a lot... Thank you !!!
Great work you have done. keep sharing knowledge.
great explanation sir, crystal clear.....
Excellent explanation. Thank you so much
Thank you you made my life easy I was worried before watching your video
Great Tutorial..Thank you so much Sir..!
Great Information. My answers for task are 62.93 and 0 % . Regards from Nicaragua
Thank you for such a brilliant explained methods
thank you so much Sir! you made things so simple for me!!
So much simpler than I thought! Thank you!!

extremely helpfull tommorow is my paper and i might be able to attempt this if it comes in exam
thank you sir that's wonderful i gained a lot from this explanation!

Thank u vry much, done a excellent job.

Thanks to you for your good presentation.
all 4 videos from part 1 through 4 is the best
Krasava.Nihuevo ob'yasnil!
Wew, my lecturer didn't taught us how to get the probability. Geez. Btw, thanks for the video sir! It's worth to "attend" your class XD
thank you so much, I have better understanding on PERT/CPM.
Thankyou sir it was very well explained
sir , you are so good and nice explanation. Thanks a lot sir, will you share the book name which you are holding while teaching.
this man can really teach
thoroughly discussed! kudos!
Thank u so much it was helpful
Excellent
Thanks a lot. Helped tons
bundle of thanku sir you really made it easy but at the end I was little bit confused but it was easy at all thanks again .....
I think there is a typo in your table. mine is 0,1293.
and since it is in the left side , you need to calculate the "remaining" area so you take your value out of .5, and that will be the remaining area.
gr8 explaination....
thanks sir..good presentation and simple explanation..
This man really teacher thanks

Awesome stuff!
Awesome videos...
realy very effective. thanks a lot
I'm in finance dept of a tractor industry. Recently I underwent a management development programme sponsored by our company. Now I can take up a project using PERT tools. Hats off Mr.romrodemarco
can we get the answers for x=26 and x=29?
for x = 29, the answer is 62.93% (.5 + .1293), and for x = 26, the answer is 25.46% (.5 - .24537)
Very Helpful !!!
62% and 25%? and so many thanks for this explanation .
Its very helpful for preparation for exam.I m failed to find out part 5 lecture.How could i collect it ? Plz help me.
There is not
thanks sir,,
Thanks sir.
Is Excellent! Thanks.
can you explain where did you get the 0.1293 ? i cant find that value for the z = 0.33 thanks sir
+Joseph Edison Duo i think you should do interpolation to get the value for 0.33
sir i am not cleared how we have fonud .1293 if possible please give me the explanation
thanks you so much sir
hello please the variance used for the standard deviation of the project is 9.1 according the question but you used 9.11 why
variance of expected time of project is sum of variance of the events.
So add up squares of (pessimistic-optimistic time)/6 for each event along the path
Along the critical path
Thank you!!!
Good
good one thanks
thanks
understandable!
i need to know how to we get the 9.1 Variants
variance of expected time of project is sum of variance of the events.
So add up squares of (pessimistic-optimistic time)/6 for each event along the path
i have understood your video clearly but that .1293 is not clear
thank u sir
Thank you
Thanks.
That last when u started explaining probability i was very confused ...... :/
Start from 7.07
He mended it
Im thankful
thanks a lot man
thanks!!
BRILLIANT!
good shit mAn
I got the same answer! XD
thanks sir..good presentation and simple explanation..
