In a drawing activity diagram when it says:

Activity A Follows Activity B

does it mean A->B or B->A?

I am confused with this lingo.

Due to your post in PMSE, I assume you are taking about network diagrams (vs. SW-engineering activity diagrams)? For network diagrams, it's like in normal language usage:

  • A follows B, so
  • A is the successor of B, or
  • B is the predecessor of A:
  • B -> A
