Consciously Evolving an Agile Team

By now it is common knowledge that it\´s just as easy for a team to fail using agile practices as it is with waterfall or any other method for building software.

The team could then work to remove the barriers between individual developers and then between the developers and the larger project team.

We eventually made headway by focusing on making changes in a very purposeful and incremental fashion, which I call "Conscious Evolution. "
