The purpose of a business organization is to create value for its customers through meaningful work. In a fast paced world, this proves to be quite a challenge. Ideas for fulfilling customer needs can be generated much faster than they can actually be realized. This is the source of much tension between the organization and its customers, but also, in the organization itself, between those that represent the customer and those that deliver to the customer. Business agility requires quite the opposite. It requires that those that suspect needs closely collaborate with those that fulfill needs. Central to the success of this collaboration is the ability to tune the fast paced idea/request generation to the slower paced request fulfillment (aka development and delivery). Customer kanban together with Upstream Kanban are mechanisms to foster this collaboration and engage the whole organization (not just the delivery team) in the move towards Business Agility.
