Difference Between Efficiency and Effectiveness
Main difference
Efficiency and effectiveness are the terms related to management. It feels like they are the same words, but actually they are both different words. Efficiency refers to the extent to which a job is done correctly. Efficiency refers to the usefulness of the work performed. Efficiency is the ratio of output to input, but effectiveness is the comparison of desired output and actual output. Both are internal terms. Efficiency is process oriented while effectiveness is not process oriented. To be successful, the process must also be effective and efficient.
What is efficiency?
Efficiency refers to the extent to which a job is done correctly. It’s about doing things right. Scientifically, efficiency is the ratio of the output to the input of any process. Our desire is to get maximum performance with minimum input, which means we want high efficiency. It is an effort and process oriented process. The goal of a task also depends on it. Efficiency depends on time. The efficiency is restricted to the current condition.
What is efficacy?
Efficiency refers to the usefulness of the work performed. It’s about completing tasks and achieving goals. It is the measurement of the process continuously to meet the actual output in accordance with the desired output. It is not effort or process oriented. It is goal oriented, but not time dependent. Efficacy holds long-term consideration.
Key differences
- Efficiency refers to the extent to which a job is done in the right way, while effectiveness refers to the usefulness of the job done.
- Efficiency is limited to current condition, while effectiveness maintains long-term consideration.
- Efficiency is effort oriented while effectiveness is not effort oriented.
- Efficiency is process oriented while effectiveness is not process oriented.
- Efficiency is the ratio of output to input, but effectiveness is the comparison of desired output and actual output.
- It is not mandatory that an efficient process be effective and vice versa.
- Efficiency can refer to the time required to perform a job and effectiveness is the level of output.
- Efficiency is time oriented while effectiveness is not time oriented.
