'efficiently-oriented' originates from the combination of 'efficiently' and 'oriented'. 'Efficiently' comes from the Latin word 'efficientem', meaning 'accomplishing'. 'Oriented' is derived from the Latin 'orientare', meaning 'to arrange or align'.

'efficiently' evolved from the Latin 'efficientem' through Old French 'efficient', while 'oriented' transformed from Latin 'orientare' through Middle English 'orienten'.

Initially, 'efficiently' meant 'accomplishing', and 'oriented' meant 'to arrange'. Over time, they combined to describe a focus on productivity.
