'precision-oriented' is a compound formed from 'precision' and 'oriented'. 'Precision' ultimately derives from Latin 'praecisio'/'praecidere' (via Old French 'precision'), where 'prae-' meant 'before' and 'caedere' meant 'to cut'. 'Oriented' comes from French 'orienter' (from Latin 'oriens'/'oriri'), where 'oriens' meant 'rising' (associated with the east).

'Precision' passed from Latin ('praecisio'/'praecidere') into Old French as 'precision' and then into Middle/Modern English as 'precision'. 'Orient' and its verbal form came from Latin 'oriri' → Medieval/Old French 'orienter' and entered English as 'orient', with the past-participle/adjective form 'oriented' later formed in English.

Individually, 'precision' originally referred to the act of 'cutting off' (figuratively exactness in measurement) and 'orient' related to 'the east' or 'turning toward'; together as 'precision-oriented' the compound's meaning shifted to explicitly denote being 'directed toward or focused on exactness/accuracy.'
