'precision-focused' originates from modern English combining the noun 'precision' and the past-participle/adjective 'focused' (from the verb 'focus'). 'Precision' ultimately comes from Latin 'praecisio' / 'praecisus', where the elements 'prae-' meant 'before' and 'caedere' (via 'cisus') meant 'to cut'; 'focus' comes from Latin 'focus' (hearth) and was extended in scientific/figurative use to mean a point of concentration.

'precision' passed into English via Old French/Medieval Latin forms (e.g. Old French 'precision') and became the modern English noun 'precision'; 'focus' entered English as a Latin loan (and later Neo-Latin scientific usage) and the verb sense 'to concentrate' developed in modern English, producing the participle 'focused'. The compound adjective 'precision-focused' is a contemporary English formation combining those elements to describe an orientation toward accuracy.

Initially, the Latin roots referred to cutting/shortening ('prae-' + 'caedere') and a domestic 'hearth' for 'focus'; over time 'precision' came to mean exactness and 'focus' to mean concentration — together they evolved into the modern combined sense 'directed toward achieving exactness/accuracy'.
