We have this big backlog in which the previous owners* were using its Stack Rank just as a criteria to put the "urgent" items in the top of the list. Whenever something was added and it was urgent or critical they used to set
Stack Rank = 1, no extra care was given to this attribute.
As you can imagine the backlog order started having no criteria (several Stack Rank 1 in the list), then they started putting minor numbers, and now we have a backlog of items like this:
Item A | 0,00001 Item B | 0,0001 Item C | 0,001 Item D | 0,01
Now we are organizing all the backlogs that we have and setting proper priorities to them.
Is there a template/advice/good practice that sets which values defines the criticality level of the items?
