Kanban Board
As you've seen by now this model inherits features from few existing methodologies/processes/models one of which is Lean process. Kaizen model is highly focused on waste tracking and removal, which is one of the priorities of Lean process as well. Kanban method works well with Lean and, by inheritance, works great with this model as they share the same goal.
It is very advisable to use Kanban method and Kanban board with this model as it would help focus on topics which are outside of scope of this document, significantly improve organization / visibility and substantially improve efficiency of process as a whole.
More on that topic can be found at: Kanban Tool web site
