What have you seen go wrong when introducing SCRUM?
Let me preface the question by telling you that our company doesn't have any formal "thou shalt..." processes in place right now at all, at least when it comes to the software development life cycle. Some areas are doing things fairly well (T/BDD at least), but we don't have a very defined process.
Our project lead was just sent to a project management training and he came back interested in Scrum (I think he just really likes the cool word ;) which is great from my perspective because for the last month or so I've been telling co-workers that Agile practices are right down our alley. Mostly we just lack the formality/structure that a methodology provides, so at times we lean a little more towards code and fix, even if individuals try to make their own corner of the world a little better.
So we're about three months into this project that he estimates to be about a 2-year project, and he wants to start adopting Scrum methods (which I'm pretty excited about). All of the developers aside from our lead are junior developers, and I think I've got the most experience when it comes to Agile practices, and it's not that much (meaning I did some BDD on a project a while ago and have watched a few Uncle Bob videos).
So the current project health is OK. We have zero test coverage, so that's not good, but our team gets along well and I think we're all fairly strong coders.
That being said, what sorts of issues should we be aware of trying to implement Scrum/Agile?
