Moving from traditional product development to agile..

The companies around the world are going agile, leaving aside the drawbacks of traditional product development processes. Transition from traditional approach to agile is not an overnight change, especially for the development teams. They have to adopt new practices which could be quite different from what they were used to.

** What are the changes you observe, while transitioning to be a part of an agile development team, as:

1) A developer

2) Designer  (UI, Software/Hardware architect)

3) Tester (quality assurance)

4) Product owner (marketing professional)

5) Project leader /manager

** What do you think are overheads (redundant /time consuming/less productive)?

** What do you think is really good compared to traditoinal development approach?
