Trello is a free on-line project management tool owned by Atlassian that provides a flexible and visual way to organize anything. This approach is naturally close to the visual boards used in the Scrum or Kanban approaches. As the tool as an open architecture, some extensions have been developed for a better implementation of Agile project management in Trello and provides additional features like Scrum burndown charts or the implementation of WIP limits. share share share share
