EXCELLENT Explanation, I've been searching for a video that clearly and concisely explains Confidence & Sigma's, this is the only great explanation I've found!
Wow, This is by-far the best explanation that i have come across for sigma and its explanation. Sir Ganttalot keep up the great work. I am a pictorial type of a person and the visuals helped me a lot to understand an otherwise weird looking bell shaped graph which didn't mean much to me.
P - O will give you a positive number result, as the Pessimistic estimate will be a larger number than the Optimistic estimate. O - P would give you the same number, but with a negative value. Either way, the difference between the two values, P and O, is the number that you divide by 3 (for triangular) or by 6 (for PERT).
Unfortunately Microsoft discontinued the PERT analysis features in the Project 2010 version. In Project 2007 there is a PERT Aalysis Toolbar to help calculate PERT values, and you can display Optimistic, Pessimistic and Most Likely Gantts. In Project 2010 you might be interested in Brian Kennemer's add-in macro. TH-cam doesn't accept url's in these replies, so search on "brian kennemer three point estimation" in Google and choose the first search result for more info.
Thanks for the tip. I'll check out Google! :) One other question. When I last studied Standard Deviation with reference to PERT, to find the Variance we would write it as O - P I noticed on your slide your write it as P - O 'Just an observation, however, this would lead to different answers' correct?
I checked out Brian Kennemer. I followed his directions to include PERT however when I went into Quick Access Toolbar and selected MACRO, PERT did not appear, therefore, I had no choice. Can you offer any suggestions? Also, When Selecting Project - Project Global I accidently clicked on the X and that selection is no longer available to me.... If I've deleted it can it be brought back? Either way without the Project Global window I can't perform this action any more. Thanks in advance.
I love this channel, and it has been an awesome tool for me to brush up... but please Sir Ganttalot, for the love of God... lose the MONSTER acronym. Testing ERrors is not a good look.
All of my videos are due a refresh, Andy. I was pretty much the first to start loading PMP videos, and since then multiple imitators have sprung up. Thanks for the advice!

Taking the PMP exam this afternoon, appreciated this video!

Great lesson. As mentioned in the video it is over simplification. Makes it easier for everyone to understand.
Thanks for sharing, actually this’s the simplest and best explanation I seen for sigma concepts
Thank you
So glad to have viewed your video, simple and clear explanation.
Thanks
That's great to hear, japharirk. Good luck with your exam!
Exceptionally helpful!
very nice work. hope to see more videos on tools and techniques. have you any thing to share on Agile ways of project management?

Thanks for uploading this video.
Awesome sir.
can you explain this one please project duration = PD± (# of σ*STD)
Can Pert and Standard Deviation be used with MS Project 2010?

Your videos are awesome! Please make more! You have an incredible gift for communicating seemingly complex methodologies; keep it up!
