Kanban is a method for managing knowledge work with an emphasis on just-in-time delivery while not overloading the team members. In this approach, the process, from definition of a task to its delivery to the customer, is displayed for participants to see and team members pull work from a queue.
The name 'Kanban' originates from Japanese, and translates roughly as "signboard" or "billboard". It was formulated by David J. Anderson as an approach to incremental, evolutionary process and systems change for organizations. It uses a work-in-progress limited pull system as the core mechanism to expose system operation (or process) problems and stimulate collaboration to continuously improve the system. It is rooted in four basic principles:
Start with existing process
The Kanban method does not prescribe a specific set of roles or process steps. The Kanban method starts with existing roles and processes and stimulates continuous, incremental and evolutionary changes to the system. The Kanban method is a change management method.
Agree to pursue incremental, evolutionary change
The organization (or team) must agree that continuous, incremental and evolutionary change is the way to make system improvements and make them stick. Sweeping changes may seem more effective but have a higher failure rate due to resistance and fear in the organization. The Kanban method encourages continuous small incremental and evolutionary changes to your current system.
Respect the current process, roles, responsibilities and titles
It is likely that the organization currently has some elements that work acceptably and are worth preserving. The Kanban method seeks to drive out fear in order to facilitate future change. It attempts to eliminate initial fears by agreeing to respect current roles, responsibilities and job titles with the goal of gaining broader support.
Leadership at all levels
Acts of leadership at all levels in the organization, from individual contributors to senior management, are encouraged.
Open Kanban
An open source, Agile and Lean based method to deliver value for knowledge work like Information Technology, Software Development, Business, Product Development or Personal organization. On the Lean side it is inspired on the work of Taiichi Ohno (Toyota Production System), Eliyahu Goldratt (Theory of Constraints) and Edward Deming. On the Agile side it takes inspiration from the Agile manifesto signers, and in addition contributions from Alan Shalloway’s Kanban for Teams, Corey Ladas Scrumban and David Anderson's early Kanban work.
It innovates by making the whole method fully open source and free to improve or modify. Open Kanban was written by Joseph Hurtado, and it has been translated by members of the community to French, Italian, Russian and Ukrainian.
