Agile Methodology Estimation

High level estimates are guesses (usually very bad and over optimistic).

In Agile, we accept that our initial high level estimates are not to be trusted. Of course, budgets need to be created and expectations need to be set.

Relative sizing means to size our stories relatively to each other and then measure how fast the team can go.
