It is said that product backlog should be estimated in grooming meeting, also teams perform estimations at task level in the how part of sprint planning meeting.
I just need clarification when estimations should be done ( sprint estimations) ?
As per my understanding, in backlog grooming we do not split the PBI at task level so task level estimations cannot be done at that time. A PBI is divided into technical tasks in planning meeting and detailed task level estimations can be done only in planning meeting ( how part )
I need experts opinion on this please....
