When 'Schema' (pattern) describes a pattern of action, it is often combined with verbs such as 'folgen' (to follow), 'anwenden' (to apply), or 'durchbrechen' (to break through). Common phrases are 'nach dem gleichen Schema' (according to the same pattern) or 'in ein Schema passen' (to fit into a pattern).
