In 2004, SEP tried adopting Agile practices. However, Agile failed to have the desired lasting impact across the entire organization. Things changed in 2007, when SEP implemented a kanban system for the first time. Kanban created an effective means for institutionalization of Lean by providing a unique method of discovering and learning practices and principles. Upon examining multiple teams using kanban systems it was apparent that teams followed similar patterns of adoption and learning. They appeared to follow the Dreyfus Model for Skill Acquisition.
