Standard Change Request process diagram

This is a worked example. Wavelength built the diagram below from the description on this page. Nobody drew it by hand.

What was said

An engineer files a change request in ServiceNow. The system runs a risk check. If the risk is high, the change advisory board reviews and approves it. If the risk is low, it is auto-approved. The change is scheduled for a maintenance window. The engineer deploys the change. After deployment, the engineer verifies the change. The change is closed in ServiceNow.

Hexagons are systems. Cylinders are data stores. Diamonds are decisions. Rounded orange boxes are people and teams. A dashed amber arrow is a link the AI inferred. Pink arrows are decision branches. Blue arrows move data.
