PERT | Calculate the project variance | Program Evaluation and Review Techniques

In this video, you will learn how to calculate the project variance and standard deviation .
PERT is used for R&D and Defence , where estimation becomes a challenge.
The following steps are followed :
1. Calculate the Time Estimate
2.Draw the project network
3. Identify the critical path
4. calculate the variance and Standard deviation of the critical activities
5. Calculate the probability of completing the completing the project for the estimated time.

Hi everyone.
To find the variance , Please use the formula (tp-to)/6)^2.
The chapters are added here :
0:00 - Intro
1:47 - Time estimate
8:11 - Network diagram
13:16 -critical path
20:04 -Standard deviation
20:40 - Variance of the critical path
22:25 - Probability of completing the project.

[@ShubhamSharma-st3hd]

Ma'am I have one doubt variance calculate me last wala 0.4444 kese aaya

[@PABHINAVYS]

SD = Sqrt(Variance)@@ShubhamSharma-st3hd

[@Viral_Hookz]

(a)How can I calculate the expected time for the completion of the project?
(b)how can I calculate the individual slack of the parts?

[@subinbmarkose]

Madam, why we are not calculating standard deviation of the critical path by adding the SD value of each critical activity?

[@ronyrahman1748]

This explanation is very clear and easy to understand. Thank u so much mam

[@tulsimohan2297]

Wow, u have explained it really well, I appreciate ur effort

[@jefferyandy7950]

Very simplified presentation. Awesome. Want to see more similar videos particularly for project management end. Cheers

[@santoshsahu-oy5vo]

Really very well explained ma'am, thanks a lot. A learner like me is understandable easily. Because I am not a student of math's 12th Bio and graduated within the BA stream and working for the last 13 years in IT (as a UI/UX Designer) even then I am getting 98% of your teaching. I am pursuing MBA from Jaipur Manipal online.

[@kurandewkupeng6446]

The explanation is very clear and easy to understand. Thank you for sharing this online.

[@sujatadas2776]

wish ,,,if you took our operations research paper. it would have been so much easier, :') you explain in such a simple way. you make it easy for us

[@keerthigakrishnan4082]

Hi, your explanation is clear thanks for your support.

[@BrhaneKinfe]

Thank you! I really appreciate your presentation

[@APTUNALEX]

Madam am from Tanzania, actually i understood your lessons, thank you

[@karpagamqtcorner8764]

Glad you enjoyed the video ! Aptunalex

[@ebakayo9183]

you are so wonder full.. you have fully talented on good explanation thanks a lot

[@highlyfavoured2422]

This is very helpful. Thank you so much for your generosity 😊

[@subinbmarkose]

Madam, why we are not calculating standard deviation of the critical path by adding the SD value of each critical activity?

[@srinivassonnaila3775]

Excellent presentation ma'm. One doubt...should we alwsys divide with 6 for grtting SD ? And...a diverging activity is burst...right ?

[@NompumeleloPretty-re6oo]

its the part of the formula

[@jessiekerry928]

Thank you for this.youre a life saver

[@motivational_gamer]

Thank you very much mam for this video.

Thank you, ma'am. You're awesome!

[@shaikjuveriyatasneemshaikj8944]

Last value is wrong for variance..??mam if possible can uh please clear it

[@joeljackson7831]

Ma'am you're Good. Thank you so much

[@paulcheruiyot391]

amazing the way you explain

[@salihdogan4950]

Thank you,
Can you enlighten me how can I determine a,b,m duration at the start of the project? Thank you

[@koushalchapagain1207]

Thank you ...very much..

[@Roudha-hv4pq]

THANK YOU A LOT.

[@shaikjuveriyatasneemshaikj8944]

Mam how to calculate variance..??

[@studymaterials599]

at 23:28 0.7874 will round off to 0.79 thwn we have to take 0.7 and 0.09 ? am i correct??

[@user-cc9qh5hi1x]

Well explained indeed 👏

[@user-gm8pg8kb6f]

Very well explained

[@kmkeerthana4631]

understanding clearly mam tq

How did you arrive at the variance?

[@sylvesterqongwane8072]

She had to square the standard deviation to reach to the values on the variance..

[@nooraalmalek137]

Thank you

[@sojanmathew6764]

Hello mam! I have a problem related to crashing. How can i share my pdf to you. Thanks

Thank You maam

How to find variance

[@daramsothakanksha1809]

Mam how to find variance and delay value?

[@socialmoth4974]

Yeah, the video skips there. I figured out the variance is the standard deviation squared. The delay probability is 100% - 78.23%.

[@harisees09]

Hello madam how to contact you ??

[@factzone5870]

Why to contact dude ?

[@yaminikonnur3658]

Formula to find tp tm and to

[@AkashYadav-po5kb]

It will be given in the problem

[@user-uc8wy7yb1q]

Hello mam please send me pdf

[@pearlgabayi6146]

36÷6=6

[@BCE_Kishores]

how do you find variance ?? @karpagam QT corner

[@MG-wf2mu]

[(tp-to) /6]^2

[@dark_side540]

variance is simply the square of Standard Deviation

[@mathswithravi]

Do u have a network diagram, seperate videos to understand ....pls take few simple problems before solving bigger problems

[@vivekkumarthakur5264]

hey, can i get your email?
