One big point which hasn't been resolved by scrum in many companies. Manual testing - until it's tested by the QA tested you shouldn't mark it done. However, it is very seldom to finish testing and implementing in one take in exactly 2 weeks. Also business analysts, together with QA testers there is virtually no control in most companies what they do and how they do. All the blame is shifted always on developers because they are at the bottom of SDLC chain but business analysts and QA testers take never responsibility for all inaccuracies and omissions of their work.
