ports-and-adpaters architecture

The ports-and-adapters architecture should be the standard architecture for HMI applications. Its parts are loosely coupled, cohesive, easy to test and easy to extend. We can apply the reverse Conway manoeuvre to create self-dependent teams with minimal dependencies on other teams. I’ll motivate the ports-and-adapters or hexagonal architecture with USB ports and adapters and look at the architecture pattern from the production, testing and team perspective. I’ll apply the architecture to the HMI terminal of a harvester.
