'einsetzen' and 'ausüben' can both mean that something is actively used or made effective. 'einsetzen' is used more for people, means, or abilities that are used for a specific goal. 'ausüben' fits more with professions, functions, power, influence, or pressure. Learners may confuse the words because both sound like activity. A simple guideline is: you 'setzt Mittel oder Personen ein' (use means or people), but you 'übt einen Beruf, eine Funktion oder Einfluss aus' (practice a profession, perform a function, or exert influence).
