The flow should be continuous and managed for instances where team boards reflect unanswered challenges.
At each stage of production, the work should be made as efficient as possible.
Team boards show where the value stream is at a team level.
Accurately and iteratively define the process and be sure that everyone can understand it.
Kanban systems rely upon every member of the work team understanding where the production cycle is at a given time and constantly seeking and relaying improvement opportunities.
There are limitations in every system, due to physics, regulation, dollars or process weakness.
Only when the constraints are understood and explored can they be addressed logically and efficiently.
Addressing constraints based on facts will improve efficiency and profit.
Once a decision about addressing a constraint has been achieved, other decisions cannot infringe upon the new process.
The process improvement system is continuous and iterative. It should constantly be flowing in a loop to keep improvements up to date.
