Getting stuff done, but in the eyes of management not fast enough. Just guessing but this seems to be the rule.

If you really need agile it will not help and if your team already rocks agile won't improve it, likely you'll already be doing something like it but customized to your needs.

I've seen a couple of fairly efficient teams utterly ruined by switching to 'agile' and I've yet to see an inefficient team become more efficient by deploying it.
