Summary

Scheduling algorithm considers Rank first than any other values such as dependencies. When there are multiple backlogs and teams working on the same Plan, it may get an unexpected result.

Steps to Reproduce

Have Backlog A and Backlog B runs in parallel on two different backlogs with assigned to two different teams.

Backlog A has the following backlog (rank in brackets):
BACKLOGA-1 (1)
BACKLOGA-2 (2)
BACKLOGA-3 (3)
BACKLOGA-4 (4)
BACKLOGA-5 (5)

Backlog B has the following backlog (rank in brackets)
BACKLOGB-1 (6)
BACKLOGB-2 (7)
BACKLOGB-3 (8)
BACKLOGB-4 (9)
BACKLOGB-5 (10)

If BACKLOGA-1 has a dependency on BACKLOGB-2 it does not schedule it straight after BACKLOGB-2 completes (which it should, because it is first in the backlog and has the highest rank).

Expected Results

BACKLOGA-1 scheduled right after BACKLOGB-2

Actual Results

BACKLOGA-1 scheduled after BACKLOGA-5

Notes

This is because, in scheduling, Rank is considered first then other values such as dependency. It is an expected behaviour, JPO-1531 open to adding this in the documentation.
