These two words may look alike, but trust us, they are far from the same. A leader needs to focus on tackling the correct issues and in accordance with priorities.
And you can do that by understanding what to manage, why it's important, and the action points. This is where efficiency and effectiveness come in.
Let's get the difference between efficiency and effectiveness out of the way first. Efficiency is the ability to do something or produce something without wasting materials, time, or energy: the quality or degree of being efficient. Meanwhile, effectiveness produces the desired result: having an intended effect. The tangible difference between efficiency and effectiveness may not have struck you before as they are often juxtaposed to each other like the yin-yang symbol. However, understanding how these two strategies work against each other, rather than being interchangeable terms, will get you on the right path to being a successful leader and helping your team succeed.
So, efficiency means optimizing resources to do the right thing in the best way possible, while effectiveness can boil down to getting the job done. In other words, something is effective if it produces the intended result, whereas it's efficient if it functions with the least use of resources. Combining the two means producing maximum output from the given input with the least. For example, Alex develops a generic sales email he can send to 100 potential clients each day. As a result, 2% of his emails lead to a sale. In other words, Alex and his efficiency refer to how well something is done. However, effectiveness indicates the extent to which something has been done, to achieve the targeted outcome. For example, Oda researches potential clients and crafts a tailored email for each. She sends ten emails a day. As a result, 40% of her emails lead to a sale. In other words, Oda and her effectiveness refer to how useful something is.
These terms are a crucial part of a leader's journey to achieve success and not end up with a team struggling to nail down resource-effective workflows while achieving results. Before moving on, let's quickly have a breakdown of what we have learned about the differences between efficiency and effectiveness:
