TOPIC: Question on Module 6 | Dependancies

I have a couple of questions on videos from Module 6. I’ve taken screenshots for clarity:

(1) In the video for Sequence Activities Part 1 there are two separate slides which show a list of activities. Both have what seem to be peculiar relationships in that Activity B is dependent on Activity C, while at the same time Activity C is dependent on Activity B. How can this be possible?




(2) In the review question for Sequence Activities Part 2, I’m not clear on the nomenclature of the activities. In the ID column, the activities are enumerated as 1, 2, 3, and 4. However in the predecessor column there are references to A, and B. Is this a typo? I can understand why the answer would be Divergence, but only if Activity 1 has multiple dependencies. It’s hard to understand what the links are if using both numbers and letters to identify activities.



Thanks.

Anthony,

My apologies for the long wait for a response. You were correct on both accounts.

We have corrected, re-recorded and published an updated version of this lesson today.
