Fizzy is our fun, modern take on Kanban (and we made it open source!)
Kanban is a simple, practical approach to visually managing processes and backlogs by moving work cards from one progress column to another. Toyota came up with it to track their production lines back in the middle of the 20th century, but it's since been applied to all sorts of industries with great effect.
