The first time I heard Kent Beck’s voice for real was in a podcast interview. I remember that he spoke with passion about concepts that were, as I listened, obviously connected with the practices of XP: trust and accountability. Still, I hadn’t made the connection that clearly up until then, so that interview stood out for me. In this video on InfoQ, Kent Beck talks more about accountability, trust, why they are so important for effectiveness – and how this relates to agile software development.
