Wouldn't toyota model essentially set a required buffer size in kanban, essentially ensuring a certain level of stock decided upon by risk management?
The pull flow would then ensure that the stock fluctuates around that value instead of being driven to 0, because taking a "card" out of stock might trigger purchasing of more stock?
Toyota (for example) doesn't get the chips directly, this is about visibility/planning/management of your vendor's vendor's vendor's. Those chips (Tier 3+) become boards (Tier 2) become center consoles (Tier 1) that an OEM installs.
The question isn't how stock is tracked or risked, its who is responsible for it.
