We use scrum in our company.
And with scrum I mean we don't have a scrum master, our senior developer is the project owner, we estimate in hours and the estimate is binding, so you are not allowed to work longer on a task than the estimate.

So yeah.. "scrum"

Estimates are always correct.

ALWAYS.

That's why they are called estimates, aren't they?

Estimates i give are accurate. But than boss doesn't agree it will take that long. So he sits their and tells me how long he thinks it should take. I tell him he's probably wrong. His estimated time flys by and than im usually right on schedule with the estimate i gave him originally.

We are not allowed to work LESS THAN ESTIMATED. beat this
