A question about the network paths: Are these mutually exclusive, or should they be worked on in parallel? Expressed in project terms: Are *all* tasks of *all* paths needed to complete the project? /OR/ are the paths variants of each other, where only the best fit is chosen? In this example: going the top path (A->B-D-G->H) will this be the whole project, and all that's needed? That's quite abstract, hope someone can understand what I mean, thanks ... :D
Yes, all tasks in the network diagram need to be completed to complete the project. In the example, Critical Path (CP) (A->B-D-G->H), will determine the shortest time (32 days) required to complete the project. In other words, you cannot complete the project in shorter time than this. For any reason if you don't do any work on non critical tasks (C,E &F), then over the period, these tasks and the corresponding paths will become critical and extend the project duration beyond the original/baseline of 32 days. For example: The Total float for task E is LS-ES= 19-9= 10 days. Therefore 10 days is the maximum time task E can be delayed. If it delays beyond 10 days, then this task will become critical extending the project completion beyond 32 days. Please note that CP is dynamic in nature and will change during the execution of the project, as per the actual progress achieved. Therefore CP has to be monitored periodically (as per schedule tracking process) and mid-course correction(s) taken accordingly to keep the project on track.
this was the issue I had as well. If you are using day 5 to complete task A - then task B cannot start until day 6. this is off by one day for forward pass according to my calculations.
The difference between LS & ES or LF & EF is "TOTAL FLOAT" and NOT "FREE FLOAT", as explained in the video. TOTAL FLOAT is the float/slack available for all the tasks combined in that particular path. Whereas FREE FLOAT is the float/slack available for an individual task in the path.
Great explanation!
Made the concept crystal clear...
TQ sir. this tutorial is straight to the point
simple and clear, thanks!
Thanks it is quite clear 🎉
This gave me a better understanding of forward and backward pass. Thank you !
dont really get the rational of es/ef having same duration as ls/lf...is that something common?

U deserve my like
Thank you so much. This gave me the much needed understanding.

B can start only after A is finish on 5th day, so B can start from 6th day only???

I think so.
minor correction at display time 6.28 on the free float = LS - ES instead mentioned FF= ES-LS
Thanks for the sharing!
isn't that for total float ?

TOTAL FLOAT is the float/slack available for all the tasks combined in that particular path. Whereas FREE FLOAT is the float/slack available for an individual task in the path.
Great presentation :)
Thanks, Big help!
Very simple
That's a TOTAL float not FREE float :/
Learn to teach !!!! Rather than self teaching lol
