in reply to Thoughts on the Agile Imposition
It doesn't cover production emergencies, high level features that *must* be implemented right away...Scrum works best when the team cannot be interrupted. If your organization does not have that luxury (i.e. if you don't have dedicated support teams to handle production emergencies), I suggest you abandon Scrum and switch to Kanban instead. The definitive Kanban reference is this Kanban book by David Anderson. FWIW, I've used both Scrum and Kanban and, like The BBC, much prefer Kanban.
