Scaling agile methods

Using agile methods to develop large systems presents a thorny set of issues. If large teams are to produce lots of software functionality quickly, the agile methods involved must scale to meet the task. After all, a small team could create the software if the functionality to be delivered was small and, conversely, could be delivered given we had the time. Scaling agile teams thus becomes an issue if the only option for meeting a system delivery deadline is to have many developers working concurrently.
