Transitioning to agile is hard. It involves learning new techniques, thinking in a different way, and stepping out of your comfort zone. No wonder so many agile transitions revert back to previous ways over time. A change in management or a loss of the agile champion is often a catalyst for this process. This talk describes several mechanisms to help counteract these forces, and how to incorporate them into your organization. Presented through examinations of real-life examples, interactive exercises and open discussions, this talk provides guidance on how to create sustainable agility.
