Kanban Software Development

Kanban literally meaning "signboard" or "billboard", is a concept related to lean and just-in-time (JIT) production. According to its creator, Taiichi Ohno, Kanban is one means through which JIT is achieved.
Kanban is not an inventory control system. It is a scheduling system that helps determine what to produce, when to produce it, and how much to produce.
In Agile software development, it has become a common practice to visualize and share project status by posting cards on a wall of the project room.
On the board, project tasks are represented by Post-It notes, and the status of each one is indicated by posting to separate areas on the board labeled "To Do", "In Progress" and "Done". This Kanban Board helps visually signal tasks and limit the volume of tasks actively being worked on, optimizing the teams focus.
KanbanFlow is a Lean project management tool allowing real-time collaboration between team members. Supports the Pomodoro technique for time tracking and best of all, it's absolutely free.
If you are engaged on a software project as a team leader, you can use this tool to coordinate the group's effort. If you're a developer you can use this individually to break down your tasks or propose it to the project manager for adoption.
