Demand Flow and Lean Manufacturing (orderless completion)

Hi,
I've been researching a solution for a large Japanese motorcycle manufacturer which has many Lean Manufacturing processes and may be Demand Flow and Lean Manufacturing (orderless completion) could be the solution we have been looking for. However, I am not sure if there are many customers using it. Have anybody know about customers working with these setups?
Thanks in advance.

Not sure, I think Harley Davidson runs on E1 ...however have no contact there nor know if they use Lean/Demand Flow, Orderless Completion etc.
