AThe tools and workflows that achieve continuous integration and delivery, run by an orchestrator
BA single script that a developer runs by hand to compile and then upload one application
CA ticketing board that simply tracks which features are ready to be released next time
DA shared network drive where finished build artifacts are stored for later download
