Strategic design - Upstream/Downstream

In this article, there is a statements which states
“However, the order process does not depend on the payment to be successful.”

I think Order process depends upon payment to be successful. How can we have a successful order completion without a successful payment flow?

Is my statement incorrect?

Hi @jd1, Because order processing is upstream. It can make payment fail. Payment is downstream since it cannot make the order process fail.

Happy Learning :))
