Organization Tasks are specific to booking and managing an Organization.  Things like those in the “Prospect” set below. "Contract Renewal" as example for Organizations that could include steps like, “010-Renewal Email / 020-Followup Call / 030-Check In”

Job Tasks are your workflow that get assigned to a job with due dates that are determined as the Collection is assigned to a job.

Also always best to include a sort number at the beginning of the stage (as you see for the Prospect Collection) so they display in order on this screen and when editing.
