1. What is Kanban?

Kanban was originally a cardboard box used to identify when it was necessary to replenish the stock required to produce a product. The system then became more efficient by making the cardboard travel with information between different stations in a production system: it is therefore a just-in-time system in which the company produces only what is needed, while reducing intermediate stocks. It is for this quality that the methods derived from this idea prove useful for operational project management. They enable tasks to be treated as just-in-time elements, i.e. as close as possible to the real need for use. It is therefore possible to transfer the basic ideas of this type of operation to the field of project management.
