by Danilo Sato

Dan North wrote an interesting post about the perils of estimation, questioning our approach to inceptions, release planning, and setting expectations about scope. This made me think about the implications of those factors once a project starts, and I came up with some anti-patterns on the usage of velocity to track progress. This is my first attempt at writing about them.
