From Agile Software Development, A DACS State-of-the-Art Report:
- Agile projects reported an increase in productivity of 15-23 percent, a 5-7 percent decrease in costs, and a 25-50 percent reduction in time-to-market.
- 84 percent of agile projects have 10 developers or less.
- Pair programming takes 15 percent longer but reduces defects by 15 percent.
- The single most difficult part in implementing agile methods (by far) is convincing management and/or other developers.
