Confessions
“I worked on a fixed time project, where they spent so much time gathering the requirements there was very little time left to actually write the code.
It was a horrible experience.”

Confessions
“I was part of a project where they ‘gathered as they go’ it was like little red riding hood skipping through the forrest hoping not to bump into the wolf.It made me shudder”
