Just to make sure that I at least got the example exercises right (IB):
1a) Station X is the bottleneck
1b) In the traditional method, they should produce product D first
2) $1,500 per month flow through the bank
Did you get the same results? :-)
Does anyone have any idea what we need to do for Session 7 (Process Management), are the pages wrong or do I have the wrong book?
Application task 7.3
Prepare discussion questions 1 (only the first 4 items) and 3 on pages 52 and 53 of Anupindi et al.
But there are no questions on page 52 or 53.
Application task 7.5
Prepare discussion questions 2 and 4 on page 86 of Anupindi et al.
Page 86 has no question and is actually in the middle of Chapter 4.
The whole tasks seem to be a bit off and I am not sure what questions to answer.
Always look at the critical path first and then crash an activity on this path first (usually the one with the most impact depending on how your critical path looks like e.g. longest crash, cheapest, on more than one path, etc ). After that, check whether your initial critical path is still critical - if yes, crash another activity on this path; if not, find the new critical path and crash an activity on this path.
Just continue doing this until you can't crash anymore due to budget or time constraints or because crashing just wouldn't shorten anything anymore :)

But in this case, the critical path remains the same even when crashed, so why would you choose to crash 1-3, 5-7 and not 3-4 and 2-6?
So are we comparing the LS from C (or D) with the EF of A to find A's slack ?

Usually you just do all ES, EF, LS and LF and then in this case you would just calculate LF-EF for A to find A's slack.
But yes, an activitiy's successor's late start will be the late finish for this activity so in this example exam, C's LS is A's LF (also because D has a later LS and you'd always take the earlier LS of different successors).
This all sounds kind of complicated but it's really just doing ES, EF, LS and LF for all activites like we've already done it in Supply Chain and MOPD :)
