1.What is efficiency?
效率;效能;功效
◎ efficiency -- (the ratio of the output to the input of any system)
◎ efficiency -- (skillfulness in avoiding wasted time and effort;
"she did the work with great efficiency")
2.What is effectiveness?
有效;有力
◎ effectiveness, effectivity, effectualness, effectuality --
(power to be effective;the quality of being able to bring about an effect)
◎ potency, effectiveness, strength --
(capacity to produce strong physiological or chemical effects;
"the toxin's potency"; "the strength of the drinks")
3.Can you tell the different between efficiency and effectiveness?
What is the different?
效能是成果與目標的關係,也就是實際產出成果達到預定目標的程度;
而效率則是輸出和輸入的關係,亦即輸出和輸入的比值。
效能的高低,例如水果刀及果皮削刀,大部份的人不擅用水果刀直接削蘋果,
而是用削刀,以一個不擅用水果刀削蘋果的人來說,水果刀還是可以產生效能,
但是比起削刀來講,比較慢。
如果是兩個人同樣要削蘋果,使用同樣的工具-水果刀(同樣效能),在一小時後,
甲完成了四十顆,而乙完成了五十顆,這樣來講,乙比甲要有效率,你也可以這麼講,
甲乙兩人同時各削十顆蘋果,結果乙比甲要早完成,那麼乙就是比較有效率。
∴ 不同的是,效能指的是有沒有效果,而效率指的是效果好不好。
