The drawing

What dependency mapping is.

Dependency mapping is the practice of drawing the systems, services and infrastructure that rely on one another. The lines identify paths such as a web application calling an API, an API querying a database, or a service sending metrics to a monitoring platform.

A good dependency map starts with one service and follows the systems it needs to work. It is useful before a change because it turns an assumed relationship into a reviewable one.

FAQ

Common questions

What is dependency mapping?

Dependency mapping creates a visual record of the systems and components that rely on each other to deliver a service or process.

Why are dependency maps useful?

They reveal shared services, critical paths and likely impact before a system is changed, maintained or taken offline.

What should I include in a dependency map?

Start with the service being studied, then add the APIs, databases, queues, identity services, infrastructure and external providers it requires.

How is a dependency map different from a network diagram?

A network diagram emphasizes devices and connectivity. A dependency map emphasizes which systems need other systems to function, even when they are not directly connected by a physical link.
