The Kanban Method has been shown to provide efficiency gains in many organisations. However, this talk will argue that those improvements have generally come through doing things righter, rather than doing the right thing. Doing more of the right thing requires challenging and testing underlying assumptions about the design and management of work, which will often lead to situations of embarrassment or threat. For the Kanban Method's approach to evolutionary increment change to become more than a fad, it needs to either provide guidance or advice about how to overcome issues that generate embarrassment or threat, or provide a more balanced view of it's potential impact. The talk will cover approaches that could increase the chances that the Kanban Method could deal with questioning assumptions around issues that could create defensiveness.
