Milk Kanban: Principles Over Practices in Agile

This article uses the example of an office 'Milk Kanban' to illustrate the essence of the Kanban method. Traditional Kanban is often simplified to workflow management with whiteboards and sticky notes, neglecting its core – visual signals. The author points out that the 'Milk Kanban' – a note attached to the last carton of milk saying 'Bring me to Kasia' – perfectly embodies the essence of Kanban: using the simplest visual signal to clearly convey information (milk is running low, needs restocking). This reminds us that Kanban system design should be simple and clear, avoiding over-engineering and focusing on core principles rather than specific practices.
