Review Upstream and Downstream

Upstream refers to the people, systems, or processes that provide inputs to the process being studied. Downstream refers to the people, systems, or processes that depend on the output.

Upstream is where this process gets what it needs. Downstream is where its output goes next and who depends on it.

Friction may appear inside one process but originate upstream or create impact downstream. Limited upstream and downstream context keeps the map useful without mapping the whole business.

If customer intake does not capture service location, the scheduling team downstream must call the customer before assigning a technician.

Upstream and downstream are not fixed positions on an organization chart. They are relative to the process being studied, and the same team can be downstream from one process and upstream from another.

Upstream feeds you; downstream needs you.
