Dear Sir,
I have two questions:
1- Equations of Network Diagram in specific:
- Activity Duration = EF-ES+1
- Activity Duration = LF-LS+1
- ES = EF of predecessor +1
- LF = LS of successor -1
Only you and PMP Headfirst explained that approach.
To understand, I pulled on solved network problem and want to see above true in some books right, others not showing that am talking about +1, -1 of the above equations. Why?
Ex. Page 90 of PMP Certification Mathematics by Vidya And Riva
9 2 11 ES Dur. EF
D Task name
19 10 21 LS Slack LF
2- Just received audio version of your postcast Cost Budgeting
hw.libsyn.com/p/5/a/3/5a3116d9237f4a9d/P...l_eid=&l_mid=1788367
Is this different from your video prepcast and where we find all audio links?
Thank You.
