Common combinations are 'erprobte Methode' (tried-and-tested method), 'erprobtes Verfahren' (tried-and-tested procedure), 'erprobte Technik' (tried-and-tested technique), and 'erprobtes Mittel' (tried-and-tested remedy/means). So it often describes abstract concepts or tools.

to learn / experience
'erfahren' and 'erprobt' both have to do with practice and real situations. 'erfahren' is a verb and here means that someone experiences or goes through something personally. 'erprobt' is an adjective and describes something that has already been tested and has proven to be reliable. The words can be confused because both sound connected to experience. In practice: a person can erfahren something, but a method, a tool, or even a person can be erprobt.
