Productivity is generally regarded as a measure of outputs divided by inputs. All of the activities that you get done in a day may be considered your output and the time you put into them are your inputs. Efficiency is a measure of how well you do those things. If you are able to get more outputs from the same inputs, you are said to have increased efficiency. Effectiveness is a measure of doing the “right things.” Highly effective individuals and companies act in ways that move their highest priorities forward on a regular basis.
• Productivity = Output / Input
• Efficiency = Doing things right
• Effectiveness = Doing the right things
In order to achieve maximum productivity and efficiency, you’ll need a method for prioritizing and arranging both your inputs and your outputs. Proper assessment and organization of inputs leads to greater effectiveness, and proper organization of outputs leads to greater efficiency. This method of organization is known as planning–the foundation of productivity. It includes creating a mission statement, goals, and values so you can focus your activities on what matters most
Efficiency speaks to whether or not something was done in the best way; the way that would create the most (correct)work with the least effort in the shortest amount of time. Effectivity is how well something produces the desired effect/reaction, and productivity is how much work has been done
Efficiency is defined as "doing things right", effectiveness as "doing the right things"
