  3. Session Description “As you adopt Scrum across your enterprise, you will find that synchronizing the work of interdependent Scrum teams is a challenge. Kanban has a number of principles and practices that can aid this synchronization and thus smooth out your adoption. This session will introduce Kanban from a Scrum perspective, show how the Lean practice of “One Piece Flow” is the key to both, and get into the nuts and bolts of specific practices and concepts from Kanban that can be adopted by an existing multi-team Scrum program.”

  4. Overview • Why bother? • Bird’s eye view of Scrum • Problems with multi-Scrum-team coordination • Bird’s eye view of Kanban • One-piece-flow (aka small batch size) • Applying Kanban basics to Scrum • Moving away from iterations • Synchronized Scrum Teams
