Agile Product Owner: How long do you think this task will take?

Me: Probably 13 points.

APO: That is too many can you break it down into separate tasks?

Me: Sure its probably an 8 and an 8. Since i need to work on them sequentially and one depends on the other, the second task will take longer if i need to make changes after the first one is merged.

~ Turned 104 (8 tasks * 13) points into 128 (16 tasks * 8 points) points.

A 13 represents a whole 2 week sprint.
An 8 represents a week and a half.
We cannot fit 2 8 point tasks in the same sprint, so now it takes 2 whole sprints to complete 2, 8 point tasks.
We have no smaller tickets so we don't work for the rest of the sprint.

Anyone else been here?
