The process-to-component dependency in ArchiMate Application Usage The Application Usage viewpoint stacks the dependency top down: business processes rest on the application services that serve them, and those services on the components that realise them, so if a component fails its services stop and the processes above lose their support.
The process-to-component dependency in ArchiMate Application Usage
A three-band vertical dependency stack for the ArchiMate 3.2 Application Usage viewpoint. The top band holds two business processes, assess capacity and publish network data. The middle band holds the application services that serve them, a capacity lookup service and a publication service. The bottom band holds three application components: the Connections portal, GIS and LTDS publication. Serving and realisation arrows point up, and a left axis says each layer depends on the one below.
