The Bug Myth
I was forwarded this post, The Bug Myth, by a college and it is a very good read. I also recommend you read the comments and provide your own.
The definition of requirement, request, bug, etc and how to “handle” them is a constant struggle, especially with the emergence of new methodologies and approaches to software development. A struggle that can often make it difficult for teams in the forming stage. It can be difficult to move into storming if the team has to pause and “validate” what was being formed.
