if you are working at a small shop or startup - then whatever makes you happy, even these classes are OK.

if you are working at enterprise - then these processes gotta be implemented according to ITIL in a specialized IT Service Management system - like ServiceNow, which allows building process flows like directed acyclical graphs and automation of necessary steps
