kanban (little k); system of signaling for pulling items to be worked. Developed by Toyota. Simple pull system.

David Anderson credited for defining Kanban (big K). Incorporates:

• Maintains Pull • Focus on Quality; Definition of Done!• Theory of Constraints• Explicit Policies• Limiting Work-in-Progress• Classes of Service• Predictability via measurement• measurement = lead time• per class of service• becomes your service level agreement

So where does Trac fit?

Kanban Board ≠ Issue Tracking(or does it?)

Simple & easy

Lots of plug-ins: visit track-hacks.org- Master Tickets – could be used to show ticket blockages- Custom fields- Typed ticket workflow- Notifications- Keywords- Metrics Plug-Ins (TracMetrix provides CFD for calculating Lead Time)

Can be configured so that person moving a ticket to a state takes ownership.

Ability to have pre- & post- hooks (e.g. prevent movement if blocked)

When moving to the next state, that person moving it takes ownership.
