'efficiency-focused' originates from the combination of 'efficiency' and 'focus,' where 'efficiency' means 'achieving maximum productivity with minimum wasted effort or expense,' and 'focus' means 'the center of interest or activity.'

'efficiency' comes from the Latin word 'efficientia,' and 'focus' comes from the Latin word 'focus,' meaning 'hearth' or 'fireplace.'

Initially, 'efficiency' meant 'the quality of being efficient,' and 'focus' meant 'hearth.' Over time, 'focus' evolved to mean 'center of interest,' and 'efficiency-focused' now means 'concentrated on achieving maximum productivity.'
