Transitioning to Agile Testing

Some test teams may be stumped on how to transition to agile. If you’re in such a team, you probably have manual tests for regression either because you never have had the time to automate them or because you are testing from the GUI and it doesn’t make sense to automate them. You probably have great exploratory testers who can find problems inside complex applications, yet they tend not to automate their testing and need a final product before they start testing. You know how to plan the testing for a release, but now everything has to be done inside a two-, three-, or four-week iteration. How do you make it work? How do you keep up with development?
